I'm trying to build a 4x4 electric wheelchair on a VERY low budget.
So far I've sourced two old w/c & added one motor to each corner, using the stock controllers I've now got basic 'tank' steering.
My question.
I have in my head to use a cheap Chinese controller for each wheel.
They use non return rotary dials for speed .
1.How could I use a pi to replace the rotary control?
2. Once we've figured out how to replace the rotary Dial, how could in combine all Four to work from one joystick?
Many thanks & have a safe & happy new Image may be NSFW.
Clik here to view.
I just found this on AliExpress:
