Uno Circuit Board. The board can be powered by 5 20 volts but the manufacturer recommends to keep it between 7 12 volts. Select the board and serial port as outlined in earlier section.
Above 12 volts the regulators might overheat and below 7 volts might not suffice. It has 14 digital input output pins of which 6 may be employed as pwm outputs 6 analog inputs a 16 mhz crystal oscillator a usb connection a power jack an icsp header along with a reset button.
