What is a bump switch?

Bump switches (sometimes called snap-action switches or limit switches) give Marty the sense of “touch”. Like all switches, they are devices used to make or break connections in an electric circuit. In robotics, they can be placed on the outside of the robot allowing it to respond to the environment.

What is a VEX limit switch?

Limit switches provide the capability to limit action in programmed behaviors. For example, a robot can be programmed to stop forward motion if the switch is triggered ON.

Step 2: Step 2: Cut a Hole in the Table

The next step was to cut a square hole in the top of the table and then I spray painted the entire table flat black. I also drilled a hold in the side of the table for the power cord to go later.

Step 3: Step 3: Ardino Code and Breadboard

I started with the following code and a push button with the setup shown to power the led strip.

Step 5: Step 5: Putting the Table Together

The next thing I did was put aluminum inside the cut out in the table, and then put a piece of plexiglass underneath and attached the capacitive touch wire to the aluminum and super glued the led strip on the inside of the table.

Step 6: Step 6: Finalizing

The last step was to put a mirror underneath the plexiglass and the led strip to help shine the light upward and then mounted both boards to a piece of wood and screwed it onto the bottom of the table.
