This project is about simulating a three phase half-wave and full-wave rectifier with resistive load. Rectifiers are circuits that convert AC voltage to unregulated DC voltage. They are used (especially a full-wave rectifier, half-wave rectifier is not used due to its high ripple factor) as the first step in converting three phase or single phase rectifier to regulated DC voltage in some DC power supplies. There is a simulation in NI Multisim. Three phase half-wave rectifier: Three phase full-wave rectifier: Download link: https://drive.google.com/open?id=15-X6cVsHbHjgXT1YAPoddkiJX75C7u0B

This project is about simulating a traffic light. There is a 1-digit common anode 7-segment which shows how long each signal is on. I connected three 220v signal lamp as its lights by a relay board which its relays work at 5v. Output voltage of stm32f103c8t6 is 3.3v so I used three transistors as switches to convert 3v output to 5v that is needed for relay board.

This project about star delta connection for a three phase motor. I did'n have three phase induction motor so I used three signal lamp instead. In star delta connection first, star connection actives and then after a while delta connection will active. The time between star and delta connection depends on how powerful your motor is. In this project it is possible to change the time from 0 second to 100 seconds by potentiometer connected to A0. I used Arduino Nano instead of any industrial PLC. The outputs of the Arduino is connected to the relay board and then it is connected to contactors. Contactor is a devise that can connect three phase voltage to an induction motor. There is a video of how this circuit works. Download link: https://drive.google.com/open?id=1rkaE7WTPg93gEQ8l0ehYUHintUx-WcQG

This project is about connecting joystick module to an Arduino. Joystick is like two potentiometer that gives analog value. My joystick has two dimensions, One is X axis and the second is for Y axis. The analog value of the joystick is from 0v to 5v that you can read it directly by analog pins of your controller. There is an additional digital switch on joystick like the usual on/off switches. I used 3 led's, the brightness of the two first led's depend on the value that joystick gives. The third led is for that digital switch that mentioned.

This project is about connecting 16*2 LCD thorough I2C protocol with Arduino Nano. The advantage of using I2C protocol for connecting LCD is that it uses only 2 ports of your Arduino while if you want to connect LCD directly to the arduino  it uses at least 6 ports. There is a shield of course to translate I2C commands for LCD and first you need to get I2C library for arduino and install it on your IDE.
