Read Duty Cycle of a PWM Signal Using Visuino & Arduino

In this tutorial we are going to read the Duty Cycle of a PWM signal using Visuino. For a PWM source we are going to use a PWM generator connected to the Arduino interrupt digital pin [2], We are going to measure the pulse width of the HIGH and LOW then use this formula TotalDuration = highDuration + lowDuration; DutyCycle = 100.0 * highDuration / totalDuration to get the Duty Cycle in percentage.
