Filtering Noisy Arduino Measurements

https://www.electronics-lab.com/filtering-noisy-arduino-measurements/

Paul Martinsen @ megunolink.com discuss about noise in analog input of arduino and how to filter it. He examines 3 filtering algorithms: Averaging, Running average, Exponential filter and provides the code to achieve that. Measurements from the real world often contain noise. Loosely speaking, noise is just the part of the signal you didn’t want. […]
