Schmitt Trigger using a Comparator If you follow @Majenko's advice of using a comparator, you could add some hysteresis to it with a few resistors to create an inverting Schmitt trigger. This will increase the noise immunity and thus reduce the noise going to the ESP8266. The following simulation has a noisy input transformed into square pulses. It also ...


Your LED is connected between V+ and the GPIO of the microcontroller. This is a common arrangement because historically microcontrollers have been able to sink more current than they can source. It's also easier to make a "low side" constant current source, which this custom chip may have, to reduce the number of external components needed. To read ...
