Generate Pulse Width Modulation PWM Signal using 555 Timer IC Circuit Diagram The output is taken from the usual pin#3 of the chip. In the above straightforward configuration the IC 555 is all set for generating the required PWM pulses, it just requires a square wave pulse or a clock input at its pin#2, which determines the output frequency, and a variable voltage input at pin#5 whose amplitude or the voltage level decides the pulse width dimensions at the output.
Working of the PWM Based DC Motor Speed Controller. The 555 Timer is configured in its astable mode, which means it will oscillate continuously between its high and low states, producing a square wave output.The frequency and duty cycle of this square wave (PWM signal) are determined by the resistors (R1, R3) and capacitors (C1, C2) connected to the 555 Timer.
