 Bigger Bigger  Smaller Smaller  Reset Reset


I've made a motor controller with the TIP120 setup but now I would like instead of giving the amount of speed, I would only want to change the direction.

Is this still possible with the TIP120 setting? Or do I need something else?(Want to have as low component count as is possible)
Also what would the sketch look like.

I've already searched google and got the setup with a relais and pot but that for controlling it with the pot. I would like the controlling be based on what the arduino is programmed too.

To change directions you need an H-bridge.  The H-bridge can be a single IC (754410 for one) or a motor control module.  There are probably dozens of tutorials on DC motor control with Arduino on the web.
