Stabilizing Analog Readings Through Software
Sunday, June 15th 2025
Having trouble getting stable analog readings from a noisy component? There's several ways to resolve this. Either through additional hardware (capacitor) or through software. Recently, I had such case. Thought I would share a quick-tip on how to solved this through software. The solution is pretty easy. Just take multiple readings and average them before returning the result. Take a look at the sample code below. I hope this helps resolve your noise!
// average 4 readings for stable reading value = (analogRead(curPin) + analogRead(curPin) + analogRead(curPin) + analogRead(curPin)) / 4;
