Hey Guys, I just found this forum and have a problem hopefully you can help with.
OK, here's my current circuit. I have a small microcontroller that controls a motor through two SPDT relays controlling voltage to a small motor. It let's me put 12 volts DC to the motor, reversing polarity so I can run it both directions. It's a 5 volt controller and a 12 volt motor.
I'm looking to get rid of the two relays. It's easy with 4 transistors if everything were on the same voltage (2 per leg of the motor, one driving high & the other low controlled by the uC), but the translation from 5 to 12 throws me off. Is there a simple way to do this?
Any advice appreciated.
Thank you
Tony
