Control de Motor a pasos con Pic16F84

Since I finished my degree in April, I have been looking for work. The search has been slow but hopefully soon I will be making the big bucks. To fill my spare time I decided to do something with the mounds of electronics and such sitting in my room. First is to build a robot using stepper motors.

Control de Motor DC usando un puente H

In this tutorial, you'll learn how to control a DC motor's direction using an H-bridge.

To reverse a DC motor, you need to be able to reverse the direction of the current in the motor. The easiest way to do this is using an H-bridge circuit. There are many different models and brands of H-Bridge. This tutorial uses one of the most basic, a Texas Instruments L293NE or a Texas Instruments SN754410.

If you simply want to turn a motor on and off, and don't need to reverse it, for example if you're controlling a fan, try the tutorial on controlling high current loads with transistors.
