 **2. LED**
-After adding the resistors, you can add the LED. When connecting the LED, double-check the polarity. The shorter leg is the cathode (-) and the longer leg is the anode (+). Connect the **cathode** to the top (10K) resistor, and connect the **anode** to P2 of the Oak using a wire (the blue wire in the example).
