Hi all! I'm using the pulseIn() function to read a PPM signal through an Arduino Micro. The problem is that the Arduino Micro operates at 5V whereas my PPM signal goes from 0 to 3.3V. Will the Arduino Micro detect 3.3V as a high level? I couldn't find these specifications in the Arduino website. So…
