-The project is based around the ElectroDragon LED Controller board, but any ESP32 (incl C3, S2, S3) boards capable of handling 5v and either 12v or 24v can be used. Make sure to match the fan voltage to the power-supply and to the ESP32 board if using the ESP32 to control power to the fan.

To get 5v for the PWM signal to the fan, set Jumper 08 to "2812". This switches the Green terminal from being controlled by pin 06 to pin 09, and limits it to 5v. By also setting Jumper 09 to "GND", we change the Red terminal to be a common ground.

SHT3x and SHT4x units should usually be connected directly to 3.3v and GND, which can be found on the LED Controller's pin header. Connect SCL to Pin 08 (pinSCL) on the header, and SAA to pin 02 (pinSDA).
