The servo motor have many utilizes in everything from robotics to puppetry to photography and beyond. These tiny motors can position their output shaft to any position on command and hold that position. Most servos possess a range of motion to about 210 degrees and thankfully are quite easy to handle with a basic circuit like the one presented right here. Working with just a 555 timer as well as a couple of support parts, this circuit can handle a servo via it is full rotation primarily based on the position of a potentiometer.
