Connecting servo motor to mbed processor

(1/1)

PBG:
Hello! I am currently doing a project where I have to drive a small servo motor from an mbed processor. However, only the supply voltage of the motor is given as 4.8-6V but not the pulse. when connected directly to the processor, the motor doe not operate and hence I guess I need an external circuitry to interface the two. A bjt amplifer can be fine but since the motor is a three wire one I do not know how to connect it and what are the external components and their sizes required. Can anyone please help me perhaps with a circuit diagram?

Thanks
PBG

Is this an RC hobby servo? OR some industrial servo?

If hobby servo then just do a google search on "RC hobby servo" for lots and lots of info about how they work and example code to control them from a processor.
If an industrial servo then you must study the data sheet for that servo.
