servo board

fount this on my daily Internet rumage. its a board that turns a servo in sequence with a poteniomiter. wonder if it could be made to control a more powerful motor?

You can further research this but servo motors need a PWM digital signal to control it. The analog voltage from a potentiometer is converted to a digital control signal with some circuitry. Ordinary motors just hooked up to power are not controlled that way. Depending on what you mean by high power, you might need an H-bridge circuit to control the motor. Good luck.
good idea
