Introduction
After working with some motor control application i found that a multi-channel PWM or Duty Cycle Meter is a quite help full to debug those PWM based motor control circuits and RGB LED control PWM using PWM which has at least 3 PWM line ,so i decided to build one for my self.
This is Meter has total 3 channels with all can accept frequency up 800Khz. the accuracy of the meter is quite good.
