Story

With this firmware you can check if your device and the integrated sensors work properly. (temperature, illuminance and soil moisture)

In the code you can see how to use GPIO connector, I2C connector and also see an example of using the lcd display.

/*AgruminoLemonTesting.ino - 
  Created by gabriele.foddis@lifely.cc         05/2021 last update 03/2023
  With this sketch and the Fritizing img you can try if your device work properly. 
  Testing: built-in led, GPIO connector, I2c connector, Pump Connector, Liv connector, WiFi Connection, and also... Lux, temperature and Soil Moisture sensors. 
  Look at the images in the folder library or in this link https://github.com/lifely-cc/agruminoLemonTesting
