Adding in a Switch

Materials

• Breadboard
• 1 9V Battery
• 1 Battery Clip
• 1 LED (Any color)
• 1 330 Ohm resistor
• Jumper Wires

Procedure

1. Connect your positive and negative terminals to the respective power rails. Do not attach the battery just yet.

2. From the positive rail, connect a wire to A4.
3. Connect a 330 Ohm resistor from B4 to B5. The polarity of the resistor does not matter.
4. Place the switch with four pins on E5, F5, E7, and F7.
5. With your LED, bend the anode (long leg of the LED that is positive) to form a curved figure that equals the size of the cathode (short leg of the LED that is negative.
6. Connect the LED’s anode to C7 and cathode to C10.

7. To close the circuit, connect a wire from A10 to the negative terminal.
8. Attach your battery

** Be sure to remember POWER RAILS CONNECT VERTICALLY and THE MIDDLE SECTIONS (A-E or F-J) ARE CONNECTED HORIZONTALLY**

Be careful with the pins on the switch
