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?
