I'm completely new to ardiuno and i got a project to build a spring stretch (displacement) meter.This is achieved by altering the frequency of oscillator circuit to which spring is attached, acting as an inductor. The inductance varies with the stretch of the spring attached to the circuit. Microcontroller is programmed in such a way to count the frequency and display the corresponding displacement on the LCD. i have made the oscillator circuit now I need help with programming the ardiuno. please let me know. i would be grateful.
