Introduction: HELPMAN CLOCK

HELPMAN CLOCK is a new medical device that measures heart rate and controls the state of assumption of your pills or insulin. It stores all data on an online database, tells you when it is the time to take your pills and automatically ejects them

This device is designed to help patients in several cases:

• In fixed schedule (chosen by software), the system emits an audio signal to alert the patient when it is the time to take pills or do insulin.

• The system is equipped with a sensor that continuously detects the heartbeat and monitors the patient's health. The data appear on the display and are saved online.

The system will be provided with the NFC sensor to communicate with the most modern sensors degree view of the patient's blood sugar levels.

NOTE: For this project knowledge of Linux system and basic electronics are needed. This is not intended as a comprehensive guide for beginners. If you do not feel confident with any part of this project, please ask qualified help .

Step 1: The Structure

You can only build a prototype of your clock, because to miniaturize the circuit is very difficult, but our team is designing a special pcb.
Now you can print the clock, with a 3D printer, only as support for the heartbeat sensor. Of course you must use existing parts of commercial clocks (which currently could hardly be reproduced, for example a watch strap).

There are three steps:

  • Disassemble the watch strap from an old watch .
  • Download the STL file linked below and print it with a 3D printer.
  • Mount the heartbeat sensor and the watch straps to the printed part.

Step 2: The System

The system consists of an Intel Edison card and modules for Arduino. The communication takes place over Wi-Fi via Edison account.
Used modules :

  • Nokia 5110 LCD module: It is a graphic 84*48 pixels LCD screen, that uses the PCD8544 controller; all necessary functions are provided by this chip. It is therefore required a minimal number of external components and a low energy consumption. The PCD8544 interfaces communicates via Serial bus interface.
  • DFPlayer Mini MP3 Player: It is a small MP3 module with an output to be connected directly to the speaker. The module can be used in combination with a UNO Arduino or any other device with features RX / TX .
  • Intel Edison: is a tiny computer-on-module offered by Intel as a development system for wearable devices and Internet devices. The system was initially announced to be the same size and shape as an SD card and containing a dual-core Intel Quark CPU at 400 MHz communicating via Bluetooth and Wi-Fi.


  • heartbeat sensor


  • Led
  • Resistors
  • Male and female pin headers
  • Push buttons

Step 3: Deploying the Prototype

The circuit is mounted according to the schematic. You can see this from the image or video.

Step 4: Intel Edison

Follow this guide to install Linux image:

Step 5: Download Arduino IDE for Edison.

Follow this guide for install Arduino IDE.

Step 6: Prepare SD Card

The SD Card houses the mp3 files that are "talking" to the clock. Download the mp3 files folder linked below and copy it into your SD Card as in the picture.

Step 7: Make the Pills Distributor

To make your pills distributor you need:

  • one box of mints
  • a servo motor
  • metal brackets
  • rivets
  • manual riveting machine
  • hot glue.

Assemble the metal brackets with rivets and fix the servo motor with hot glue.

Connect servo motors to intel edison

Step 8: Final Steps, Testing and Power On

Mount the boards and wire the sensor, load the software with the Arduino IDE.
