Arduino + BLE Demo: HeartBeat Detector

Goals:

You will learn how to

⦁ add a sensor to an Arduino board

⦁ program the Arduino to read data from the sensor

⦁ program the Arduino to send the sensor data to the mobile phone

Prerequisites:

⦁ Arduino IDE is installed with the libraries

  ⚬ BLE SDK for Arduino

  ⚬ RBL-nRF8001

⦁ HeartbeatDetector.aia

⦁ HeartbeatDetector.apk

⦁ HeartBeatDetector.ino

⦁ Arduino Board + BLE shield

⦁ Arduino KY-039 Detect the heartbeat module

Exploration:

⦁ Connect the Arduino and the sensor in the following way-

⦁ Load the HeartBeatDetector.ino file into the Arduino Board with the Arduino IDE

⦁ Install the HeartbeatDetector.apk on your phone and start playing with it

  ⚬ FYI - If you are not using the board number 2, you need to load the aia, change the BLE address, and then build the new apk

Challenges:

⦁ Try to understand and explain to yourself the code in the HeartBeatDetector.ino

⦁ Load the HeartbeatDetector.aia into the App Inventor BLE instance - http://128.52.185.189:8888/

⦁ Try to understand and explain to yourself the code in the HeartbeatDetector.aia

⦁ Replace the heartbeat sensor with the temperature sensor  and make something.

⦁ Show us what you’ve made in the next class --- optional, but strongly encouraged
