In this opportunity we will perform a fast test to a matrix led with the integrated MAX7219 with module ESP8266 and so that it is not very simple we will read the temperature of a sensor DS18B20.
In future tutorials we will integrate it to other platforms such as Google spreadsheet, emoncms, node-red, cayenne, ubidots

Step 6: ​Conclusions & More Tests

Conclusions & More tests

For a long time I wanted to test these LED arrays, and it can be denoted that they are perfect for projects that require visualization, simple configuration, good price.

We will use it in a variety of projects such as:

Power Meter Chint DDS666 Simple Phase 3200imp / kwh + ESP8266 12E

Electricity consumption meter Peacefair PZEM 004 + ESP8266 & Arduino Nano
