MQ2 Reading different gases Sensors Arduino Forum


20210506· Using Arduino. Sensors. louisbourdon August 8 , 2013, 7:14pm 1. Hi all. I am using this code example from Sandbox Electronics to read from the MQ2 gas sensor. However, all my readings are 0. If I use a simple analog reading on the specific pin, I get the expected analog values from 0 to 1023, usual values around 250, and if I expose it to gas for example goes up to 1000. The reason I want ...

Generate PPM signal with Arduino | QuadMeUp


20160526· In the beginning of this year I''ve written a short tutorial how to read PWM signals from RC radio with Arduino. While it is can be useful when building own RC equipment, it does not help much when one has to deal with PPM (CPPM) signal. Let''s be honest, PPM is much more useful than PWM: all RC channels are sent over single wire. On one side, it simplifies electrical design.
