In this tutorial we will learn how to read the status of a LED from the Micro:Bit‘s LED matrix, using MicroPython.
In this tutorial we will learn how to turn on and off specific LEDs from the micro:bit‘s LED matrix, using MicroPython, including controlling their brightness.

The objective of this post is to explain how to control the LEDs of a LED matrix using 2 74HC595 ICs and a ESP8266 microcontroller.
The objective of this post is to explain how to create a simple LED Matrix using PNP transistors and a ULN2803A integrated circuit, and assuming that only one LED needs to be connected at each time.
