Remote control crawlers (like the g made r1 I'm using in this project) sometimes offer 4 wheel steering. From what I could find, there is no way to toggle between standard 4 wheel steering, and crab walk steering. Basically... how do you create a toggle to reverse servo direction of just the rear steering? Thats what this does. It uses the switch on a standard traxxas controller to toggle between standard and crab walk.
Watch video demo on youtube or find more info on my website.
This is the main program that you see running in the video. I've it set to start up on boot... so you just turn the car on and you can toggle between standard 4 wheel turning, and crab walking.
A test program that will (roughly) detect variations in a PWM signal
A test program that will listen to a PWM signal and control a servo. This basically is just a "passthrough" of the value... to an observer the behavior of the servo based on the remote control actions is the same as if there was no custom software running in the middle.
A test program that allows you to enter duty cycle to test the limits of a servo.
