The Digital Only GPIO Pins

RX - also known as Digital #0, this is the hardware serial input pin

TX - also known as Digital #1, this is the hardware serial output pin

Digital 3 - this pin can also be used as a PWM output pin using analogWrite()

Digital 4 - Nothing particularly special about this GPIO pin

Digital 5 - this pin can also be used as a PWM output pin using analogWrite()

Digital 6 - this pin can also be used as a PWM output pin using analogWrite()

Digital 8 - Nothing particularly special about this GPIO pin

Digital 9 - this pin can also be used as a PWM output pin using analo gWrite() It's

also good for driving servos because its a high-speed PWM output

Digital 10 - this pin can also be used as a PWM output pin using analogWrite() It's

also good for driving servos because its a high-speed PWM output

Digital 11 - Also known as the SPI MOSI pin. this pin can also be used as a PWM

output pin using analo gWrite()

Digital 12 - Also known as the SPI MISO pin

Digital 13 - Also known as the SPI CLOCK pin
