74HC595 Shift Register with Arduino UNO Control 8 digital outputs using only 3 Arduino pins with the 74HC595 serial-in-parallel-out (SIPO) shift register. The 74HC595 is useful when an Arduino project ...

modified to run with 74HC595 shift registers so you only need 3 pins. This is an Arduino library for driving Switec X25 miniature stepper motors. It was written specifically for the Switec X25.168, ...

When it comes to the basics for microcontroller beginners, it has to be "blinking an LED." Connect an LED to a GPIO and toggle it between HIGH and LOW. That's it. It's easy. Too easy. So, I decided to ...

The ability to write Python on microcontrollers with the likes of MicroPython and later CiruitPython has made them much more accessible. [MakerClassCZ] brings that to game development with PicoGame.

"Aren't there fewer microcontroller GPIOs than I thought?" situations like this come up. In my case, I was thinking about a circuit to control multiple motor drivers from an ESP32, and as the number ...

Arduino RFID technology works by using electromagnetic waves in the radio frequency spectrum for wireless communication and data transfer between RFID tags and readers. From supermarket anti-theft ...
