Currently trying to assist my son with a science fair project. Basically a robotic hand that basically moves up/down and left/right - sort of like the motion of a wrist. The goal is to make it wireless. The servos will be controlled by basically the same thing as a rc head tracker - you move your head and the "wrist" moves with it. We have made the headtracker using a nano and gyro board and uploaded the code we found online and it works great... according to the GUI interface that came with the code.
We found a rx/tx schematic (basically to control servos on rc plane with telemetry (which we don't need) on one of the rc forums, but the whole thing turned out sketchy... the code was in hex form and although I am ~ok with code, not very certain what was going on. Had a very tough time, and actually errors uploading the code onto a promini with cc2500 rx/tx module.
We would like to use something like a nano, and a tx/rx module that works well with it. Had no issues uploading code on the nano.
Can someone please help us moving along on this? Does anyone have a schematic for a wireless rx/tx module that basically controls up/down and left/right and maybe the ability to turn a light on/off by switch or push button on the tx unit?
I'm pretty good at following a schematic, but would need some help with code, or possibly code that already exists?
ANY help is GREATLY appreciated. My son is starting to get bummed out thinking we may not be able to accomplish his project goal. Thank you!!
