In this example, we show you how to complete the "Hello World" of hardware: blinking an LED. We will also show you how to PWM the LED.

Setup

Use a small resistor, about 150 ohms (give or take) and a green LED on a breadboard.

Pin connections to LED:

Nova IO0 to LED Anode (+)
LED Cathode (-) to Resistor
Resistor to GND
