I am completely new to Arduino, and I was wondering how to connect my Sabertooth motor shield to my Arduino Mega. The Sabertooth has a forward/backwards channel, and a left/right one. Each of the channels has three wires, but I was told I only need to use the yellow/orange one and the brown one. I have no idea as to how to connect the two boards together. Is there someone that can tell me which pins to put where? Thank you a lot in advance!https://www.robotshop.com/media/catalog/product/cache/1/image/800x800/9df78eab33525d08d6e5fb8d27136e95/s/a/sabertooth-dual-12a-regenerative-motor-driver.jpghttp://www.openhacks.com/uploadsproductos/arduinoadkfront.jpg
Hi Hanspeterrv and welcome to the RobotShop/Lynxmotion forum.
This Sabertooth Dual 12A motor controller is aim to be use with a RC receiver system.
That said, you can control RC Servo with an Arduino so you can also control this motor controller, it will just be a little harder than a conventional motor controller.
You will most probably need the Servo Library:
As for the connection, you have to use PWM capable pins on your Arduino Mega for the signal (Orange Wire).
You need to hook one of the GND wire between the motor controller and the Arduino (Brown Wire) on the “GND” pins.
The Red wire is leave alone as it is use to power the receiver with the internal BEC of the Motor Controller.
Don’t connect it to the Arduino.
