Servo motor by Arduino Nano

This project is about running a servo motor using Arduino Nano. My servo is SG90 and that is a really small servo motor. I did not supply my servo with 5v output of Arduino because that takes much current from Arduino Nano. Instead, I used LM7805 regulator for my servo. There is a potentiometer (variable resistor) I used to change the position of the servo. Arduino Nano reads the analog voltage that resistor creates and thorough PWM port changes the position of the servo. My servo can be in position from 0 to 180. There is a simulation in Proteus.

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
