[En-Nut-Discussion]Problem with ADC

[Tim Tait]

ADCRead() returns a 10 bit value (on the AVR).

Watch out for integer truncation in your math (ex 5 / 1024 = 0). You may 
want to store values in units of mV instead of Volts.

You can set the ADC clock divisor with a limited range of values 
describer in the AVR datasheet. Depending on the AVR main clock input, 
it is possible set the ADC clock faster than the hardware actually supports.
