Write on 7-segment with 74LS48 by Arduino Uno

This post is about writing numbers on 2-digit 7-segment with 74LS48. The advantage of this IC is that you do not need to build numbers by yourself, this IC will do it so you will be able to use only 4 ports of Arduino ( instead of 7 ports if you want to create numbers manually). Probably, you may have restriction at the number of ports available, in this case 74LS48 can be used. There is a simulation in Proteus.
IC information was taken from datasheet.

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

Write on 4-digit 7-segment with keypad by Arduino Nano

This post is about how to use a keypad for writing on 4-digit 7-segment. The program can be used when you want to add number to your program. I keep the number into a variable and also it can be seen on your 7-segment at the same time. I did not use any special 7-segment IC driver and it is running just by refreshing all the time. You can also clear the number and add it again. Download link: https://drive.google.com/open?id=1e29RDuZhZqAuWE6OfeeHcSGl3NJpqpSV

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
