ARM7-LPC2148 PWM Tutorial: Controlling Brightness of LED As we know microcontrollers take analog input from analog sensors and use ADC (Analog to Digital converter) to process those signals. But what if a microcontroller want to produce an analog signal to control analog operated devices like a Servo motor, DC motor etc? Microcontrollers don’t produce output voltage like 1V, 5V instead they use a technique called PWM for operating… |
