What do you mean by PWM (Pulse Width Modulation)?

1.	What do you mean by PWM (Pulse Width Modulation)?
Answer» Have trouble ADJUSTING the brightness of the LEDs in your project? Changing the voltage of the power supply directly in the circuit isn't easy. In that case, you can use Pulse WIDTH Modulation (PWM). Pulse Width Modulation (PWM), also referred to as PDM (Pulse Duration Modulation) refers to changing the amount of power that is delivered to a device. PWM is a TECHNIQUE for generating an analog signal from a digital source and is an efficient way to control the amount of energy delivered to a load without wasting any energy. PWM regulates voltage and is therefore used to control brightness in Smart Lighting Systems and also to control motor SPEED.
