I have a Seeeduino mega.
I want to read several analog values. (Sharp IR, Adxl312, LDR, Microphon)
When I Read the Values they switch very fast.
I 'll give you an exmample. My ADXL312 (Accelerometer) lays flat on the table and the value switches very fast (501, 512, 521, 498, 504, 517.....)
You know what i want to explain?
In only one case it works. If I use a potentiometer.
I hope my english is not soo bad, that you can't understand what I mean.
