Digital Input Sensing

Digital input/ Dry Contact input Sensing Circuit



When NC (normally closed) is detected at the input, the microcontroller will receive a Low (0V) signal and a high (5V) signal will be received for NO (normally open).

Schmitt trigger for cleaning up noisy or slow-rising digital signals

  A Schmitt trigger is a circuit that converts an analog input signal into a digital output signal with hysteresis. It's characterised b...
