Check your work!

• The color bands on the resistor should be red-red-brown-gold.
• The resistor’s leads should be plugged into a socket by the center rail’s red line and the right breadboard’s a-16 socket.
• The LED’s longer lead should be plugged into the right breadboard’s d16 socket, and the shorter one into f16.
• The black wire’s ends should be plugged into the right breadboard’s j-16 socket and the other end into a socket by the right power rail’s blue vertical line.

Test the Circuit

• Reconnect the USB cable to your computer.
• Did the light come on?  If not, go back over the Check Your Work list again.
