Hi! "Serial1" is the serial port of Arduino Pro Micro, which is the microcontroller the code is written for. If you want to use another kind of MC such as arduino UNO you must swap every occurency of "Serial1" with "Serial" to use Hardware Serial or use SoftwareSerial library instead (https://www.arduino.cc/en/Reference/SoftwareSerial) , and of course you also need to change the pinout of the mosfets to some PWM outputs. If you can't manage out the solution by yourself don't worry, soon i'm going to update the guide with videos and a code for arduino UNO as well.
please let me know if you have any other issue, and i will be glad if you would send me a picture of the finished project :).
