Star Delta Starter with Arduino Nano

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

Traffic light by STM32F103C8T6

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.
