Programmable three-phase controller for use with an on/off switch.
Programmable on-off control of a three-phase induction motor, as the name implies, is fully programmed, that is, the on-time and off-time of the motor must be set, and the motor must be turned on and off at the specified times. As a result, because the system is designed in this manner, the motor must start at a specific time. Already, the programme is enthralled with such zeal.
In addition, an IR sensor has been installed in the circuit connection to ensure system safety, and a password-based circuit has been installed so that we can operate the circuit by entering a password.
Aside from overloading and single phasing, there is also protection against phase imbalance, change in phase sequence, and short circuiting.
DEVELOPMENT AND INTRODUCTION OF SYSTEM
Control of a three-phase induction motor with programmable on/off switch
As the name implies, our system is fully programmed, which means that the time and days on which the motor should be turned on and off will be determined automatically at that specific time because we designed the programme already in such a passionate manner when we created it.
In addition, we included an infrared sensor in the circuit connection for added safety, as well as a password-protected circuit, which allows us to operate the circuit with a password.
Additionally, overloading, single phasing, phase imbalance, change in phase sequence, and short circuiting are all protected against.

ARDUINO-BASED CIRCUIT BREAKER WITH PASSWORD OPTIONS
The Password Based Circuit Breaker is a straightforward system that aids in the control of electrical circuits. Electrical accidents involving linemen are becoming more common these days, particularly when repairing electrical lines. This is primarily due to a lack of communication between the electrical substation and maintenance personnel. This system provides a solution to this problem in order to ensure the safety of linemen. The lineman is in charge of controlling the electrical lines (turning them on and off) in this proposed system. This system is designed in such a way that maintenance personnel or other personnel can easily access it.
A controller from Microchip, the ATMEGA328P is a high-performance, low-power device. The ATMEGA328P is an 8-bit microcontroller based on the AVR RISC architecture and is designed for low-power applications. It is the most widely used of all AVR controllers because it is used in ARDUINO boards, which are the most popular of all.
How to Make Use of the ATMEGA328P
The ATMEGA328 controller is used in the same way as any other controller. The only thing left to do is programme. The controller simply executes the programme that we have provided at any point in time. Controller simply remains in place without doing anything if no programming is done.
CHANGE OF TIME
Alternatively known as a timer switch or simply a timer, a time switch is a timer that controls the operation of an electric switch controlled by the timing mechanism.
In 1945, Intermatic introduced its first time switch, which was used for “electric signs, store window lighting, apartment hall lighting, stokers, and oil and gas burners,” according to the company’s website. In 1952, a consumer-oriented version was introduced.
The switch may be connected to an electric circuit that is powered by mains power, including via a relay line, and the user must enter a password in order to turn on or off the electrical line in question. After that occurs, in the event of a failure in an electrical line, the lineman will safely shut down power to the line by entering a password and then return to the substation, where he will turn on power to the specific line by entering a password. In order to protect each electrical line from being compromised, passwords are assigned for each electrical line.
IR REMOTECONTROLSWITCH IR REMOTECONTROLSWITCH
System description: This system describes a technique for adding the capability of remote control to an electrical appliance. The goal is to build a black box into which you can plug in your air conditioning appliances and control the ON and OFF operations with a TV or DVD remote that uses a modulated infrared (IR) pulse train with a frequency of 38KHz or higher. The advantage of this system is that it is flexible.
does not make use of a microcontroller and is solely dependent on the CD4017 decade counter integrated circuit. Component specifications are provided.
As previously stated, the controller must first be programmed, which is accomplished by writing the appropriate programme file into the ATMEGA328P FLASH memory. Following the dump of this programme code, the controller executes this code and responds appropriately.
The following is the complete procedure for using an ATMEGA328P:
Using this, you can burn the HEX file of the written programme into the ATMEGA328P flash memory.
Disconnect the programmer and connect the appropriate peripherals for the controller in order to start the system. Low voltage equipment, such as battery-operated equipment in vehicles, is also acceptable. It can be integrated into power circuits (as in the case of a central heating or water heater timer), plugged into a wall outlet with equipment plugged into the timer rather than directly into the power point, or integrated into the equipment itself.
The timer can be set to turn on or off equipment, or to do both, at a predetermined time or times, after a predetermined interval, or cyclically. After a predetermined amount of time, a countdown time switch turns off the power, which is usually off. A cyclical timer is a device that switches equipment on and off at preset times over a period of time, then repeats the cycle; the period is typically 24 hours or seven days.
There are a variety of uses for time switches, including saving electricity by only using it when necessary, switching equipment on or off or both at specific times required by a process, and home security (for example, switching lights in a pattern that gives the impression that premises are being watched) to reduce the likelihood of burglary or prowling.
Applications include lighting (including interior and exterior lighting and street lighting), cooking devices such as ovens and washing machines, and the heating and cooling of buildings as well as automobiles and other transportation vehicles.
The built-in automatic washing machine controllers are examples of extremely complex electromechanical and electronic timer cycles, starting and stopping a variety of processes including pumps and valves to fill and empty the drum with water, heating, and rotating at varying speeds, with various combinations of settings for various fabrics.

Initially, it was too short. When power is supplied to the relay coil, the common terminal is switched from the NC pin to the No pin, effectively disconnecting the remaining power.
The time switch is supplied with a constant current, and the timing of the motor’s on and off periods has been programmed in advance. Once the on-time period has passed, the supply is maintained, and the output of time switch 1 is fed into a step down transformer, which converts the 230 volt AC to 12 volt AC, and the output of the transformer is fed into a bridge wave rectifier circuit, which converts the 12 volt AC to 12 volt dc, and the output of the bridge wave rectifier circuit is connected to the timer 555 IC, and the output pin of the timer 555 IC is connected To you normally closed pin and supply is continued for 1 minute as the time set in the timer 1 in the same way the timer 2 will operate when its on time is obtained the important thing is that when the timer to gets on and supply continues further it results in switching off the motor therefore the common pin of the relate to is connected normally closed pin initially and when the supplies given in the relay coil gets energised and the common terminal Swift on normal is connected to the common terminal Swift on normal is connected to the common terminal Swift on normal is
Electrical Circuit Breaker with Password Based Construction
The proposed system operated with the help of an Arduino board, which was connected to a four-channel relay via a relay interface. The Arduino ATmega328IC, which is used for programming, is a microcontroller. On the left side of the arduino board, there are five analogue output pins labelled A0, A1, A2, A3, A4, and A5. These pins receive the output from the ic.
Control of a motor or a pump
Circuit for controlling a timer
In the control circuit, we used two time switches: one that turned on the lights and another that turned them off.
The supply is connected to the line terminals of the timers and to the third pine of both timer supplies, so it has been disconnected.
On the primary side, the output of the first timer is connected to the primary side of a step-down transformer, which is a centre tap transformer with a current rating of 1 A.
The bridge wave rectifier is connected to the secondary 12v alternating current of the transformer.
It is connected to the eighth Vcc pin of the 555 timer IC as the output of the rectifier circuit.
The reset pins on the 8th and 4th rows of the IC are shorted together. We used a 555timmer IC to provide the time delay to the relay, and we connected a 100k ohm resistor and a 47micro F capacitor to the IC to ensure that there was no time delay. To connect the relay coilterminals, the output of the ic is taken from pin number 3 and connected to the relay coilterminalsic. A 440v alternating current supply is provided to the common pin of both relays, which was initially shorted to the common pin and No pin of relay 1. as a result, when power is applied to the relay, the common pin is switched from normally open to normally closed, allowing the couple to continue to operate. The same connections are made for the second off timer as well, with the exception that the common pin of relay 2 and the NC pin of relay 2 are shorted.
Digital input pins are located on the right-hand side of the board, and they are designated by the numbers 0 to 13. Pins 2 and 9 are connected to the matrix keypad pad, and pins 10 and 13 are connected to the IN 1 – IN4 of a four-channel relay, respectively, on the other side. The Arduino board receives a 5V DC supply from an external power supply. By looping the supply from the 5V pin of the IC to the Vcc pins of both the LCD display and the 4channel relay, the supply is made available.
and the ground pins of both the I2C module and the 4channel relay are connected to the ground pin of the ic through the use of a looping connection.
The LCD I2C module has four pins, which are Vcc, ground, SCL, and SDL. The SCL and SDL pins of the I2C module are connected to the analogue pins of the A4 and A5 integrated circuits.
It is connected to the buzzer alarm circuit via the A0 pin, so that if the invade password is incorrect, the circuit will activate and the buzzer will sound. The other terminal of this circuit is connected to the ground pin of the integrated circuit (IC).
The common pin of a four-chennel relay is connected to a 230-volt power supply, and the common pin is shorted to the NO pin for all of the relays at first, with the NC pin of relays 1, 2, and 3 being connected to the NO pin.
,4 are connected to the time switch, and 1 is connected to the 230 V load terminal.
, DC lock circuit, and lighting circuit, to name a few.
When a 5 V DC power supply is connected to the Arduino and the LCD display initially displays Enter password, the Arduino is considered to be operational.
The display shows successful after you have entered your password. If you have entered a wrong password, the display shows wrong password and an alarm circuit activates to alert you that you have entered a wrong password.
After entering the correct password, the digital signals are passed to the IC ATmega328 as input, where the IC processes the signals and outputs them in the form of analogue output, which is then used to operate the load.

All of the circuit components that we used in our system, the first of which is the time switch, the second of which is a
D.O.L. starter (dead on arrival) Circuit diagram for the Programmable control circuit is depicted in this figure. The time switch receives its input from a two-pin contactor, and its output is connected to a step down transformer, which converts 230 volt single phase alternating current to 12 volts alternating current, and the secondary of the transformer is connected to a bridge rectifier, which converts 12 volts alternating current to 12 volts direct current. We used two timer ICs, one for the on timer and the other for the off timer, to provide a time delay. The value of the time delay is selected according to the rating of the capacitor and resistor circuit connected to the timer IC. The output of the timer IC is given to a 12 volt relay. The fore on timer normally open(NO) pin of relay is connected to common so that when the supply is given to the relay it shifts from no to on.
Time switch characteristics The characteristics of the time switch that we used in our system are that it is a four-pin time switch that is supplied with a battery; the first two pins of the timer are input, and the last two pins are output; we can programme the timer to run 24 hours a day; the voltage rating of the time switch is 220 volts to 250 volts; the frequency is 50 or 60 Hz; the temperature range is 0 to 55 degrees Celsius; and the current rating is
CB is the password.
Basically, a password-based circuit-breaker is a microcontroller-based circuit-breaker, which means that as we insert the password, if it is correct, the corresponding relay will open; otherwise, an alarm and LED will indicate that we have entered the wrong password, and the circuit will remain in its off position. Below is a circuit diagram of the password-based circuit-breaker using the microcontroller.
