Return to Previous Lesson: Writing the Code

Lesson Overview:

Now we'll build the lamp!

Step 1: Diffusing Light

Just like with other LED projects, diffusing the light will make this much more attractive. Ping pong balls, little lampshades from paper or plastic, whatever you have handy will work. You can also choose whatever LED color you like!

  1. Continue to the next step.

Step 2: Designing a Touch Interface

One cool thing about capacitive touch sensors is that you can embed them under other materials to make them invisible. Capacitance can be measured through thin layers of non-conductive materials like wood and plastic. Some project-building tips are below!

Have fun designing your own touch sensitive lamp!

  1. If you do cover the sensor, increasing the surface area of the sensor using a wider strip of aluminum foil or copper mesh will make it more sensitive.

  2. You could make a base for the lamp out of cardboard, thin wood, or cloth, and line the inner surface with foil attached to your sensor wire. The whole base of the lamp would then act as a touch sensor.

  3. If you make changes to sensor construction, update the threshold variable in the code whento ensure that you’re still getting a reliable result!

Congratulations, you have completed this project!
