Jan 29, 2021· Arduino boards contain a 10bit analog to digital converter (ADC), so this gives us a value between 0 and 1023 depending on the position of the potentiometer. Because the servo motor can only rotate between 0 and 180 degrees, we need to scale the values down with the map() function. This function remaps a number from one range to another.

ARDUINO analog inputs have a very high impedance, so any stray voltage picked up can cause random readouts or ''beepbeep'' when no RFpower is applied, in this case, put a 220k or 470k resistor from FWD and REFL inputs to ground. Off course all wiring to coupler must be shielded and properly RFdecoupled !

Jul 01, 2021· Registriert seit: Jun 2015. RE: MQ2 Gassensor => fragwürdige Ausgabe. Die 9VBatterien sind nicht wirklich zu gebrauchen. Sie haben eine viel zu geringe Kapazität und einen hohen Innenwiderstand. Da die Versorgungsspannung bei Deiner Messung als Referenzspannung dient, wirst Du damit immer Probleme haben.
