LED Pens

LED Pens are (in our case) EXPO markers modified to have a battery, wire, an LED tip and a button.

Role in the Project
LED Pens are essential to this project. They are needed so that the people can write on the boards. In order for them to work, you press the button on the "pen" and aim at wherever you want to click on the board. By doing so, it clicks whatever you want it to click on the board. It can also be used to "click and drag" anything for the project.
