I have an Arduino UNO board that im just using as a development board (im programmign directly to the Mega328 and not using the Arduino GUI)
I have setup 2 pots to the ADC0 and ADC1 that connect to a lcd... the values seem to be a bit bouncy.. ie. I will move the pot to a position and it will go 49,48,49,48,49,48 until finally it setlls settles on 49..
in the datasheet it says "AVCC with external capacitor at AREF pin"
Om tje Arduino specs it doesnt show (or im reading it wrong) where the AREF pins connects too.
so my questions.
1# is this what would stop the "bounce".. b# is that what is even happening? 2# how do i access this pin 3# what size capacitor can u suggest?
