LEDS (light emitting diodes) are commonly found in many different types of electronic devices ranging from traffic lights to electronic toys. When the current passes through the semiconductor material of the LED it causes it to glow. These can easily be used in nearly every situation normal lights can. In contrast from a regular light however, LEDs use less electricity, give off more light and produce less heat than an incandescent light. They are also present in many of today’s tiny technology devices in a smaller size and are ideal for printed circuit boards.

An Easy LED Circuit Board
LEDs are ideal for beginning electronic hobbyists due to their smaller size as well as their versatility. With this brief tutorial you will have a better understanding of how to make an LED circuit.

You Will Need
- 1 Circuit board (Breadboard will work the best for this project.)
- 1 9-volt battery
- 2 pieces of 1-inch wire
- 1 100-ohm resistor
- 1 Small LED

Directions:
1. Wrap a single loop of one of the wires around the positive terminal of your 9-volt battery.

2. Insert the other end of that wire into the first hole of the first row and first column of your circuit board.

3. Take the resistor long wire in the same row and insert it in the second column of the circuit board.

4. The short wire of the resistor should then be inserted in the second row and column of the circuit board.

5. In the second column of the circuit board, insert the long wire of the LED into the hole in the third row of the circuit board.

6. The next step is to place the short wire into the hole located in the third row, third column of the circuit board.

7. Wrap a single loop of your other wire around the negative terminal of the 9-volt battery.

8. Insert the other end of the negative wire into the hold in the fourth row, third column.

Now at the conclusion of the final step, the LED should light up, signifying that the circuit is compete.
