i have purchased wiper motors and tried just hooking the wiper motor to where the servo motor hooks to and using it like that but there is not anywhere near enough power to run the wiper motor. i heard about the h bridge and read up on it a little and got a small idea of what they do but still have no idea how to pick the right one. Do i need a very specific one or just one that will let my 7.2 1500 mAh battery run the servo as a sensor and a 12v moped battery for the wiper motor. Im a little out of my league here so if anyone could help me out with this i would be greatly appreciative.

Ah the elusive Wiper Servo.
Many have tried, few have succeeded.

Here's some info you might find useful.

From what I've seen though, it is possible to steer a rather large car with 2 x quarter scale servos.

I was thinking along the lines of a wiper servo for one of my projects, but it seems like all too much work and too many variables that can go wrong for a number of reasons.

Might still give it a go one day though.




Or you could do what this guy did and add a gearbox to your servo.

what i really need is something that converts 7.2 v in 12v or either lets me control the flow of a 12v battery to a wiper motor with a 7.2 servo which is what i think the h bridge does but i don't know how that works so i don't know which one to buy.

Did you read the thread about Homebrew monster servos?

Send a PM to Da_Mad_Maori who started that thread.
He bought a couple of boards and will tell you which one he used and what the results were.


There's a bit more to it than just buying a couple of components and connecting 4 wires.
