How to Make an LED Light Display
Making an LED light display is a great starter project. (LED image by URIO from Fotolia.com)

Building a simple light-emitting diode (LED) light display can be a great project for both children and adults. A simple LED light display can be built using several LED lights, a resistor and a battery. Once the LED lights are soldered together, they can be mounted in virtually any container or mounted to a board in a pattern of your choosing.

Instructions

  1. 1

    Solder the positive (red) lead of the battery holder to one end of the 1K ohm resistor.

  2. 2

    Attach the free end of the resistor to the positive lead of the LED. The positive lead of the LED is the longer of the two leads. Solder the negative lead to the positive lead of the next LED. Continue to wire the LEDs, negative to positive.

  3. 3

    Attach the negative (black) lead of the battery holder to one lead of the push-button switch. Solder the other push-button lead to the negative side of the last LED.

  4. 4

    Connect the battery to the battery holder. Activate the push-button switch; the LEDs should light up.

  5. 5

    Disconnect the battery, if needed, to mount the LEDs to your chosen container.
