Making an LED Circuit
LEDS (light emitting diodes) are commonly found in many different types of electronic devices ranging from traffic lights to electronic toys. Current passes through the semiconductor material of the LED, causing it to glow. They can be used in nearly every application as regular lights. In contrast from a regular light however, LEDs use less electricity, give off more light and produce less heat than an incandescent light. LEDs can also be quite small when used for any of today’s miniature technology and custom printed circuit boards.

An Easy LED Circuit
LEDs are ideal for beginning electronic hobbyists due to their smaller size as well as their versatility. This abbreviated “how to” will give you the basics for making and LED circuit.
You Need the Following
- 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
Instructions:
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. Insert the long wire of your resistor into the same row as your wire, but 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. Insert the short wire into the hole in the third row, third column of the board.
7. Wrap a single loop of your other wire around the negative terminal of the 9-volt battery.
8. Using the opposite end of the negative wire, place it in the hole of the third
At the completion of Step 8, your LED should light up since you have completed your circuit.

You have completed your PCB prototype, congratualtions! There are many other introductory circuit projects available on the Internet. In fact, if you feel like being creative, you can use this same step by step process and modify it slightly to include buzzers, fans, speakers or switches. Use your creativity and have fun.
