Pwm Circuit. It can be observed that the motor is still running even after the power has been cut off from it. Turn up your duty cycle to get more ma.

Pulse width by definition is the elapsed time or time taken between rising high and falling low edges of a single pulse. 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 operational amplifier ic1 amplifies the input audio signal through variable volume controlled potentiometer vr1.
We will get into the reason for such a name later.
Pulse width modulation pwm or pulse duration modulation pdm is a method of reducing the average power delivered by an electrical signal by effectively chopping it up into discrete parts. Turn up your duty cycle to get more ma. Pulse width is the duration of another signal usually a carrier signal used in transmission. I think the actual circuit did not correspond to the diagram.
