arduino script to control differential thrust of two brushless motors

arduinoDuoThrusterESCControl

Arduino script to controls differential thrust of two brushless motors.

features

• 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

example behavior

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%

pin-out

The pins are configured to work with Arduino Nano boards (tested with Atmega328).

see constants for pin out and adjust when desired
