Hi all,
I am having trouble getting my head around debouncing for the various sensors I am using. I have the bounce2 library and have used the bounce library before only with buttons.
This time and I am using a range finder, a slider (potentiometer), an accelerometer, a wind sensor, and a button. I have included the code that I have done so far.
Every reading jitters by an integer or 2 and I was wondering if anyone could point me in the right direction to be able to get more stable readings?
Do you debounce say a wind sensor which has a more continous flow of reading in the same way as a button?
Thanks!
Asha

Analog Input
Demonstrates analog input by reading an analog sensor on analog pins 0-5 and
sending out a serial message of the value of the sensor attached to that pin.
The circuit:
* Potentiometers attached to analog inputs 0-5
* center pin of the potentiometer to the analog pin
* one side pin (either one) to ground
* the other side pin to +5V
