The ATmega controllers used for the Arduino contain an onboard 6 channel (8 channels on the Mini and Nano, 16 on the Mega) analog-to-digital (A/D) converter. The converter has 10 bit resolution, returning … WebRead Something. Reading from the EEPROM basically follows the same three-step process as writing to the EEPROM: Send the Most Significant Byte of the memory address that you want to write to. Send the Least Significant Byte of the memory address that you want to write to. Ask for the data byte at that location. fothergills fremantle
