I/O- All 54 digital bins on the Arduino 2560 can either be used as an input or an output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts and each pin can provide and receive a maximum of 40 mA and has an internal...
Brown-out detection, or BOD for short lets the microcontroller sense the input voltage and shut down if the voltage goes below the brown-out setting. To change the BOD settings you'll have to connect an ISP programmer and hit "Burn bootloader". Below is a table that shows the available ...
