Pulse Width modulation using 565 IC Engineering Projects
Pulse Width Modulation, or PWM, is a technique for getting analog results with digital means. Digital control is used to create a square wave, a signal switched between on and off. This on-off pattern can simulate voltages in between the full Vcc of the board (e.g., 5 V on UNO, 3.3 V on a MKR board) and off (0 Volts) by changing the portion of.
Electrical Pulse width modulation sensor circuit Valuable Tech Notes
A PWM, or 'pulse width modulation' signal is used to reduce the electrical power supplied to an electrical device by switching the signal on and off at a high frequency. As the relative on-time of the signal increases or decreases, so does the average voltage of the signal. This average voltage provides an equivalent lower power, while.

PWM stands for Pulse Width Modulation; we will get into the reason for such a name later. But, for now understand PWM as a type of signal which can be produced from a digital IC such as microcontroller or 555 timer. The signal thus produced will have a train of pulses and these pulses will be in form of a square wave.
