Electronic Airsoft Knock Down target

This is an variant of my simple Knock Down Target which adds computer control. A set of IR slot sensors allow a microcontroller board such as an ESP32, arduino, or raspberry PI to detect when a target has been knocked down, and through use of a servo motor it can stand the target back up, or knock targets down itself, as desired.I admit that when it came to writing the software to do this I ran out of enthusiasm, so I provide all of the source code and files here if anyone else wishes to take this project and progress it further. The included code has two game modes, one where it simply stands up again immediately any target which is knocked down, and other where it stands up only one target at a time randomly, chosing another when that is knocked down. It should be fairly easy for anyone with the coding skills to add all manner of timed game modes and scoring via a web interface, such as automatically knocking targets down when a timer expires.The full list of the components that I us
