Digital pins. Use these pins with digitalRead(), digitalWrite(), and analogWrite(). analogWrite() works only on the pins with the PWM symbol

Reset button. Resets the ATmega microcontroller

USB port. Used for powering your Genuino Uno, uploading your sketches to your Genuino, and for communicating with your Genuino sketch (via Serial. println() etc.)

Pin 13 LED. The only actuator built-in to your board. Besides being a handy target for your first blink sketch, this LED is very useful for debugging

Power LED. Indicates that your Genuino is receiving power. Useful for debugging

TX and RX LEDs. These LEDs indicate communication between your Genuino and your computer. Expect them to flicker rapidly during sketch upload as well as during serial communication. Useful for debugging

ATmega microcontroller. The heart of your board

Power connector. This is how you power your Genuino when it’s not plugged into a USB port for power. Can accept voltages between 7-12V

Analog in Use these pins with analogRead()

GND and 5V pins Use these pins to provide +5V power and ground to your circuits
