Matrix Display with Max7219, ESP8266 and GY-21 in Micropython

Beschreibung

A nice big display alone can’t be everything. After all, you don’t buy a car just to put it in the garage so it doesn’t feel so alone. That’s why the blog for this set shows the use of the matrix display with GY-21 temperature and humidity sensor and ESP8266. Because of the few components, this project, as well as the matrix display itself, is well suited for beginners. With the large LED matrix, you can nicely output the values of the HTU21 sensor after implementing the project.

The following products of the project are included in the bundle:

• GY-21 HTU21 moisture and temperature sensor
• Jumper Wire cable 3 x 40 pcs. 20 cm M2M / F2M / F2F each
• Mini Breadboard 400 PIN with 4 current rails
• NodeMCU Lua Amica Modul V2 ESP8266 ESP-12F
• Max7219 8×32 4 in 1 Dot Matrix LED display module
