This post is about the WS2812B LED strip, which is an addressable RGB LED strip. The information in this post also works with other similar LED strips, such as strips of the WS28XX family, Neopixel strip and others.
Continue ReadingGuide for DS18B20 Temperature Sensor with Arduino
In this guide I’ll show you how to read the temperature with the DS18B20 temperature sensor with the Arduino board. The DS18B20 Temperature Sensor The DS18B20 temperature sensor is a 1-wire digital temperature sensor. This means that you can read the temperature with a very simple circuit setup. It communicates on common bus, which means that you […]
Continue ReadingGuide for 8×8 Dot Matrix MAX7219 with Arduino + Pong Game
The dot matrix that we’re going to use in this guide is a 8×8 matrix which means that it has 8 columns and 8 rows, so it contains a total of 64 LEDs. The MAX7219 chip makes it easier to control the dot matrix, by just using 3 digital pins of the Arduino board. I think the […]
