Troubleshooting:
LED Not Lighting Up?
LEDs will only work in one direction. Try taking it out and
twisting it 180 degrees (no need to worry, installing it
backward does no permanent harm).
Program Not Uploading
This happens sometimes, the most likely cause is a confused
serial port, you can change this in tools>serial port>
Still No Success?
A broken circuit is no fun, send us an e-mail and we will get
back to you as soon as we can:
You should see your LED blink on and off. If
it isn't, make sure you have assembled the
circuit correctly and verified and uploaded the
code to your board or see the troubleshooting
tips below.
Before you can use one of the RedBoard's pins, you need to tell the
RedBoard whether it is an INPUT or OUTPUT. We use a built-in
"function" called pinMode() to do this.
When you're using a pin as an OUTPUT, you can command it to be
HIGH (output 5 volts), or LOW (output 0 volts).
digitalWrite(13, HIGH);
pinMode(13, OUTPUT);
Code to Note:
Real World Application:
Almost all modern flat screen televisions and monitors
have LED indicator lights to show they are on or off.

LEARN. SHARE. HACK.
This is a section dedicated to the most
common mistakes made while assembling
the circuit.
Here you will find examples of the circuit
you just completed in the real world.
Many of the theories in these circuits are
used in things you use everyday!
