Activity link broken? See if it's at the internet archive
This activity requires a Pico Cricket (tiny computer). Learners work on designing and building a sound sensor out of household materials, like plastic wrap and cardboard. This will connect with the Pico Cricket to "hear" claps and sounds. Learners then program the Pico Cricket to respond with light, motion, or music. Learn about sound waves, vibration, inputs, outputs, sensors, microcontrollers and programming.
