Using the Feather 32u4 Bluefruit and the TFT FeatherWing to make an Emoji Badge! The idea is that the TFT will display emoji which are selected using an iOS or Android app. The smart-phones communicating with the Feather via Bluetooth. I'm not sure if it's going to work at the moment!
3. Add a microSD card to the TFT (FeatherWing) containing open-source emoji images converted to bmp from png.
4. Test drawing the bitmaps to the TFT
5. Test Bluetooth comms using the Adafruit app
6. Develop and build an Android App using Android Studio. That's ok because I can use this on Windows or Linux. We want a menu to select the emoji from the app, then we communicate with the 32u4 via Bluetooth, and get the TFT to display the associated bitmap emoji which is stored on the microSD. The app will also need to guide through Bluetooth pairing the devices.
7. Try out some 3d printed cases with the magnetic pin backs.
8. How about adding a silicon sheet to the front of the housing for some waterproofing?
9. We'll need an iOS app developed and built too!
10. Test battery performance, can we use a 100mAh battery instead (3g), or a 150mAh (4.6g)?
Hi everyone, I got started today on my project to make an emoji video badge! The concept is that you wear a small video badge (6cm screen size) and it displays emoji depending on your current mood. You can pair your smart-phone to it via Bluetooth, and update the emoji via an app. It could also have switches to update emoji, so it could be used in schools for children to signal to the teacher how they are getting on!
