The elderly are in need of our help. We will help.

What it does

PocketPal is a microcontroller application that detects falling over using a MicroBit and sends a signal over serial (to be upgraded to radio/bluetooth in the future). If no cancellation is initiated within the countdown, the receiever then broadcasts a call and SMS request to Twilio in order to call emergency services and texts closed ones.

How I built it

  • Twilio
  • Microbit
  • Google
  • Google cloud services
  • Sweat and tears

Challenges I ran into

  • Broken Microbit sensors
  • Bad online IDE
  • Awful support for Bluetooth and accelerometer

Accomplishments that I'm proud of

  • Making the world a better place

What I learned

  • Never trust documentation

What's next for pocketpal

  • A better microcontroller that actually supports Bluetooth properly
  • Broadcasting to other pocketpals using radio so that they can pick up the signal and make the calls/SMS
