When working with extensive sets of servos, LEDs, or other such devices it's a good idea to build a breakout board of sorts. The purpose of such a device is to minimize the tangle of wires you're dealing with by creating a plug-in system that has power, ground, and signal wiring p...
Pulse Width Modulation (PWM)is a technique that varies the width of a pulse while keeping the wave frequency constant. The PWM technique mainly used tocontrol the brightness of the LED,speed of DC motor,controlling a servo motor,or in other cases, where have to generate an analog signal usi...
