Can any body plz tell me how to construct H-bridge so that i can drive 12v 10 rpm dc motor using 89v51rd2. I have two 9640 for p type high side switching and two 80NF55 N type mosfet for low side switching. I have 4 BC547. I tried it but no result. Can somebody properly guide me hw to do that.
I also suggest you to use any one drive IC. In one of our project we use L298 for control two dc motor with only one L298.
Using L298, you can also control direction of DC motor (forward or reverse).
google the L298 and you get more information about how to control DC motor with this IC.
