Circuit Stickers are electronic stickers that you can use to build glowing, sensing, and interactive projects without any complicated equipment or programming skills. All you need is your imagination.
And this is an add-on sticker kit for Circuit Sticker Starter kit, with sound sensor, light sensor, trigger sensor and an ATTiny85 microcontroller. There is 1pcs for each sticker.
Building circuits with them is fun and easy -- just stick them onto a surface like you would with a normal sticker, and build up a circuit by sticking several stickers together and adding a battery. They’re an approachable way to learn and create electronics through craft, whether you’re just starting out with circuits or creating complex interactive artworks.
