Circuit Stickers Sensors Add-On
Sensors Stickers include a light sensor, a microphone sensor for detecting sound, and a timer circuit that turns on your circuit for five seconds at a time.
We are planning to end-of-life these stickers, and have limited stock. We expect we will be out of stock in late March/early April 2017. If you need these for a workshop, please email us at email@example.com.
