Technical requirements
In this chapter, we will create an iterated prototype of Message Bag – therefore, we need the prototype created from the previous chapter. We will also look at activities that use the following:
- Arduino software as the IDE and access to https://io.adafruit.com/
- The Adafruit QT Py ESP32-S2 or the Adafruit QT Py ESP32-C3
You will need your prototype from the previous chapter, which was made with the following:
- Adafruit QT Py - SAMD21 Dev Board with STEMMA QT
- An RFID reader: Mifare RC522 with five corresponding tags
- Sewable Flora NeoPixels and a Flora Sewable 3-Pin JST Wiring Adapter
- Adafruit LiPoly Charger BFF Add-On for QT Py and a rechargeable battery, with 3.7V and a 2-pin JST-PH connector
