Technical requirements
This chapter has a practical element where you will experiment with circuits. You will need the LilyTwinkle ProtoSnap Kit for the circuits. It contains the following items, which you may choose to swap out or purchase separately:
- The LilyTwinkle board
- A sewable coin cell battery holder (switched or not)
- A coin cell battery
- Sewable LEDs
- Stainless steel conductive thread
- Sewing needles
For the last activity, we will use a Circuit Playground board, the Gemma M0 board, and the Arduino IDE, which is available for free at https://www.arduino.cc/en/software.
