Hello i was wondering if part harvesting is compatible with these boards or if parts must be specificly bought for arduino.
Everything works with arduino, you just need to figure out how. There will probably be almost nothing in that joystick of use to you, but it's always fun, and good practice, to rip it to bits and find the datasheets for the ICs.
Find a chip, read the model code on the top of it, and google " datasheet" e.g. "4n35 datasheet"
I have a stash of "dumpster dived" circuits and occasionally they come in handy for large capacitors, mosfets, & ferrite cores, but generally it's just enjoyable and educational to get in there with a soldering iron and spend some time on google to figure out exactly what you just harvested, and how you might use it. if you do it enough, you'll know what to leave alone, and what might be useful.
