H-bridge

[eng.hossam]

hello,i'd like to make H-bridge for my motors to control them in both direction and its speed.

my motors need 24 V and 5 A to work perfectly ,any help?

I haven't built one, but I've read write-ups on Instructables that might help. Here's one:

I also found this write-up at let's make robots:

If you want to control speed you'll need something that generates PWM signals.

Which normally involves a microcontroller.

I'm a fan of Microchip, but lots of other different microcontrollers, such as the Arduino, which seems to be quite popular on this website and many others will do a similar job.

I hope this helps.
