  • How to add 6 extra pins to your Arduino with no extra hardware

    This must be one of the most stupid instructables I´ve ever encountered.First of all you don´t add any extra pins... correct title would be "how to use the analog pins as digital on your Arduino". second this is a STANDARD arduino feature and can documentation can be found on the Arduino site ( https://www.arduino.cc/en/Tutorial/AnalogInputPins... )And to set, for example, analog 0 as output and high you just can use pinMode(A0, OUTPUT); digitalWrite(A0, HIGH);(Note that even have to figure out the pin number, the A[n] aliases just work )And finally, one should NOT drive leds without current limiting resistors on any Arduino output. The Atmel controlers are not designed for that and multiple leds connected this way can destroy your microcontroler.Ahhh and as bonus....see more »This must be one of the most stupid instructables I´ve ever encountered.First of all you don´t add any extra pins... correct title would be "how to use the analog pins as digital on your Arduino". second this is a STANDARD arduino feature and can documentation can be found on the Arduino site ( https://www.arduino.cc/en/Tutorial/AnalogInputPins... )And to set, for example, analog 0 as output and high you just can use pinMode(A0, OUTPUT); digitalWrite(A0, HIGH);(Note that even have to figure out the pin number, the A[n] aliases just work )And finally, one should NOT drive leds without current limiting resistors on any Arduino output.
