[arm-allstar] Fan control via GPIO and control circuit you can get from Amazon

[Arthur Putnam]

I would like to use the following control circuit, to control a bun fan to cool radio. 
SunFounder Relay Module for Arduino and Raspberry Pi 5V DC Trigger by HIGHLO (HIGH Trigger)

I am looking for script to use this control circuit and how to apply it to the Rpi 3+ I am using.
Any ideas or feedback would be much appreciated.
