I2C LCD with Arduino Nano

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.

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

Blinking LED by STM32F103C8T6

This post is about running a blinking LED with STM32F103C8T6. This code was written in MDK Version 5 - Keil. I used a transistor as a driver to prevent MCU from over current cause ARM CPUs work with 3.3v and can not provide high current output. I uploaded program with ST-LINK programmer. Delay is 500 ms and you can change it in the program. There is a simulation in Proteus. Download link: https://drive.google.com/open?id=1b5yuQiFmAGQk1EN5_WoC0AhpC-9L2_Co

Switch on and off a LED with AVR ATmega16

This project is about turning on and off one led by ATmega16 AVR microcontroller. One push button is used for turning LED on and one is used for turning it off. There is a simulation in Proteus.   Download link
