In this article we will discuss the PWM with Flowcode. Pulse width modulation (PWM) is a technique of controlling the amount of power delivered to an electronic load by switching ON and OFF a digital signal. This is the simplest technique that can be used to produce analog voltages from a digital one. The fraction of the period for which the signal is ON to the total period is known as the duty cycle. The average DC value of the signal can be varied by varying the duty cycle. The duty cycle can be anywhere between 0 (signal is always off) to 1 (signal is constantly on).
