Simple Servo Motor Controller Parts List:

R1 = 820 Ohm 1/4W
R2 = 68K 1/4W
R3 = 10K 1/4W
R4 = 1K 1/4W
R5 = 1K Linear Taper Pot
C1 = 1uF/16V
Q1 = 2N3904 / 2N2222
U1 = 555 Timer IC
MISC = Board, Wire, Knob For R1, 8 Pin Socket For U1

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.
