I'm trying to connect a Tetrix DC Motor Controller to work with 2 stepper motors (from the Tetrix kit) that typically run on 12 V. But, I'm unsure of how to connect it back to the Arduino. I currently have a circuit set up on the breadboard with 3 0.01 uF capacitors, and it is all running on one 9 V battery.
Any help or advice is welcome.
