Arduino script to controls differential thrust of two brushless motors.
- program will execute ESC arming steps on startup
- it then takes two analogue inputs, "overall throttle" and "drive direction" and translates them to differential speed of two PWM controlled ESC/Motors. Meaning the "drive direction" input will affect the difference in thrust between the left and right ESC-PWM signal. The difference will be increased up to the point where one motor will turn as fast in reverse as the other will turn forward
- it offers also a drive direction input to control general drive direction
- enable debug_output flag to see values on serial monitor; this is slow though
| Throttle | Direction | Motor Thrust Left | Motor Thrust Right |
|---|---|---|---|
| 50% | 0% (= full left) | -50% | 50% |
| 50% | 50% (= straight) | 50% | 50% |
| 100 | 75% (= half right) | 100% | 0% |
The pins are configured to work with Arduino Nano boards (tested with Atmega328).
