I want to use a windshield wiper motor as a steering servo. How do I convert and amplify the the servo signal from my hobby reciever to run a 12v wiper motor? Thanks
The LM website has servo drivers, pick the largest one. They drive DC motors. Watch the current draw! Some of the drivers work from the R/C PWM signals generated by your receiver.
Check out Chuck’s page on servo drivers:

Below is a thread concerning making 12v motor servos. The key seems to be making/buying an H-bridge that can handle the current of the larger motors. I got stopped on my H-bridge at the point I needed to add two additional transistors to the H-bridge I was making, and haven’t had the time to get the soldering iron to make the changes.
