Assist to design an Arduino Sketch for an Arduino Uno with LCD shield to analyse/graph an analog input testing the compression of a rotary engine.(A repeating signal with 3 unique eg 1-2-3, 1-2-3...)
The rotary engine has 3 separate compression chambers (rotor1, rotor2 and rotor3) and need to be identified. (A repeating signal with 3 unique eg 1-2-3, 1-2-3...)
Analog input will be logged at as high a resolution as possible over a 5 seconds time period (possibly to SD card) after which the highest values for the 3 peaks will be mapped from raw analog value to actual sensor values displayed on screen and the peaks per minute calculated.
Please see the attached picture to demonstrate an example of the analog input.
