Puck_Buzzer

Normal Version with Bangle.js 2, and Puck.js

How to Test:

• Upload Puck.js code, disconnect from IDE.
• Upload Bangle.js code, disconnect from IDE (if needed to start scan).
• Press the Puck.js button → Watch should buzz + beep and display response time!
• Press the Bangle.js BTN to reset the screen.

What Happens:

• Teacher asks a question
• Kids press the Puck.js like a buzzer
• Bangle.js shows:
• Who buzzed in first
• The time it took
• Fun feedback like "🎉 You're first!" or "⏱️ 1.5s"
• You can also log response times for multiple attempts.

Notes:

• This uses Nordic UART UUIDs (6e4000xx) — make sure Puck.js is advertising that (which it does via Bluetooth.println()).
• It connects once and listens.
• The TextDecoder is available on Bangle.js for BLE data — no need to polyfill.
