Make your stuffed animal interactive using the Microbit!
PlushPal is an app that lets you design interactive toys that make sounds based on movement. You'll be able to record custom gestures for your toy and learn about how to interpret sensor data from the Microbit using machine learning.

<aside> 🧸 Items
<aside> 🖥️ Technology - 1 Microbit
<aside> ⤴️ The hex file will enable your Microbit to send sensor data to the programming interface over Bluetooth
Download this hex file: https://github.com/ttseng/plushpal/blob/main/firmware/plushpal.hex and load it onto your Microbit.
(right click on the
Raw button and click
Save Link As to save the file)
Once your hex file is loaded, you should see this face on your Microbit.
It's important that the Microbit is securely attached to your stuffed animal so that the sensor readings are consistent!
You can use a hair tie to attach the Microbit directly, or if you have a bit more time, we recommend constructing a backpack to hold it in place.
Quick Method (fast but least secure)
Use a hair tie or rubber band to attach the Microbit directly
Paper Backpack (15 min)
Build a paper-based backpack from a cereal box
Felt Backpack (25 min)
A backpack you can sew using felt and thread - the most secure (and cute!)
<aside> 🌐 You can find the PlushPal app at https://www.plushpal.app/.
Because the app connects to the Microbit using Web Bluetooth, you must use Chrome on desktop (Web BLE is not currently supported in other browsers or on table devices).
