Reference
readAdc (channel)
This function has one parameter for reading the ADC value of the corresponding channel.
For example:
readAdc (0)
Read the ADC value of the batteries voltage. The returned number ranges between 0-255. Divide the
obtained value by 255.0 and then multiply by the reference voltage of 5.0V, and then triple the value to
get the batteries voltage.
