I was trying to decide what to do, as a ‘productive’ project with my arduino this weekend, when I stumbled upon my old wired xbox 360 controller, and remembered my RC car that no longer functioned.
…Wired the basic functions of the controller- RB and LB momentary switches, and X & Y axis trimpots from left and right analog joysticks. Decided to do it this way, reading up on proprietary USB blah blah blah Microsoft junk made using the existing serial communication dang near impossible (or at least way too time consuming for a ‘fun’ project)
Wired cat5 to the RC car functions- 1 pair each for drive motor, steering motor, ‘horn’, and headlamps. The arduino was fairly easy to wire up. I used a VCR motor drive chip for the forward and reverse action, and a DPDT relay for left and right steering. 2V 3A external power supply for the motor driver….
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
