wheelchair1.inoCurrent version of the Arduino program that does the magic. The program reads the inputs from the analogue joystick and translates that into a direction+PWM signal to command each motor driver. There's an algorithm in place that processes the joysetick input and limits the jerk to make the ride smooth. The program also takes an optional BLE connection that can be used to remote-control the wheelchair.x-arduino - 15.52 kB - 07/15/2019 at 08:42 |
