Example of a macro with the RGB Lights

If the neopixels doesn’t light up and you are 100% sure you have EXP1 connected to EXP1, try flipping the connector.
If you are going to use a chamber thermistor (3rd thermistor) don’t forget that this board only has 2 default input for thermistor and a 3rd input hidden in the display output that is now busy with a proper display. You are going to loose the ability to connect this 3rd thermistor to the display output. We recommend you to buy from our store the thermistor expander that connect to the TFT output. Final result of both thermistor expand + screen adaptor would be like this:
