Using H bridges for driving motors
« on: March 04, 2009, 12:04:54 PM »
Can anyone give me more details on using H bridge for driving the motors? I don't want to use any ready-made ICs. I want to build my own H-bridge. I am using LDR sensors to detect a white line and hoping to connect it to the H bridge.

Other questions:
1. Can H-bridge be used to stop one motor, while the other one continues to rotate so that the robot, as a whole, turns as the white line curves?

2. How do we control the speed of the motor connected to the H-bridge?

the problem with h bridges is that u have to make a single hbridge for each motor...and why don tu want to use premade ic's /...they are pretty useful and really help...why do u want to go through the tedious job of making one urself

You can build your own (rather than from a shop). Check out my tutorial in the members pages - I give various circuits.

You need an H bridge for each motor

You control the speed using PWM.
