Code

The code in the editor below is ready to run! After you have plugged in Code Lab and have a green power light, hit 'Upload Your Code' and the red LED of Code Lab should start blinking really quickly, plus you'll see 'Success!' pop up on the code editor.


/* Blink Code Lab's red LED light on and off 10 times per second */ void setup(){ pinMode(2,OUTPUT); //Set pin 2 to receive power } void loop(){ digitalWrite(2,HIGH); //Turn on pin 2 delay(50); //Wait 50 milliseconds (0.05 seconds) digitalWrite(2,LOW); //Turn off pin 2 delay(50); //Wait 50 milliseconds (0.05 seconds) }

Having trouble uploading code? Try these steps in order:

1) Make sure you’ve completed the process at www.letsstartcoding.com/start. There are helpful steps there!

2) Make sure your board is plugged in snugly. You should see a steady green light on your board when it it powered on.

3) Try plugging your cable into a different USB port on your computer. If that fixes it, it doesn't mean the first USB port is broken, it may just be that your board didn't establish a connection with your computer the first time.

4) Unplug other USB devices from your computer to ensure nothing is interfering with the connection.

5) If this is your very first time using your kit, you may need to restart your computer after setting everything up, especially if you manually installed drivers on a Windows computer.
