自作LEDゲーム機『ゲームベーダー』をつくるにあたって、まずは10個以上のLEDを扱えるようになりたいと思った。一番簡単なのはマイコンの入出力ピンをLED毎に割り当てること（10個なら10本）だけれど、それだとあっという間にピンを使い切ってしまって ...

All microcontrollers have specific numbers of IO pins but in some applications, like in a 7-Segment Display, we will need more GPIO pins than what our controller could offer. For such cases, where ...

Raspberry Pi is an ARM architecture processor based board designed for electronic engineers and hobbyists. The PI is one of most trusted project development platforms out there now. With higher ...

This project demonstrates how to implement SPI communication on the ESP32 using the ESP-IDF framework to control multiple LEDs through a 74HC595 shift register. It provides a clear and practical ...

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

In a recent video our hacker [Electronic Wizard] introduces the 74HC595 shift register and explains how to use it to drive 7-segment displays. [Electronic Wizard] explains that understanding how to ...

What is the 74HC595 IC? The 74HC595 datasheet specifies that this IC is a 8-stage serial shift registers with a storage register and 3-state outputs. The registers have separate clocks. contain an ...
