This project was created on 03/15/2015 and last updated 2 years ago.

Description

In this project I take an old Motorola Bravo pager and replace its insides with my own PCB that fuses an ATmega328 (with Arduino bootloader), Bluetooth Low Energy, a vibe motor, a piezo buzzer, and some ws2812b leds. The original form is maintained, including AA battery power and two external buttons.

In it's current state, the pager beeps, blinks, and buzzes whenever I get a text message. It's a bit silly, sure, but a fun exercise in reverse engineering and design.

This is primarily a hardware project, so minimal effort was put into the Android and Arduino coding.

@josephchrzempiec I wrote my own android application to interface with the bluetooth module.  It was very ugly.  I'd check out one of Adafruit's examples.  This might get you started: https://github.com/adafruit/Bluefruit_LE_Connect_Android

For the arduino sketch, Adafruit has a nice tutorial here: https://learn.adafruit.com/getting-started-with-the-nrf8001-bluefruit-le-bre

Hello  i looked all around and i couldn't find anything to help me out the adafruit one didn't really help me because the lack of skills i need for the arduino app. I need someone help to help me make one. As far as the sketch goes the one from adafruit someone pointed me in the right direction but really didn't help me much.
