Check & Test the LED Circuit

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.
