Today we continued making our own pressure sensors, which control the brightness of an LED by how hard the sensor is squeezed. Once we finished building the sensor circuits, we attached them to foam stress toys to create our own pressure sensing, light-up stress toys!
We also learned that circuits don't always work on the first try, and how to "debug" them. This is an important part of the process! In the words of Thomas Edison: "I didn’t fail 1,000 times. The light bulb was an invention with 1,000 steps."
