One of the coolest things about micro-controllers is their ability to communicate externally, in a sense making them Internet of Things devices. The Genuino 101 has an inbuilt Bluetooth Module, let's explore how to connect it and what your students can do!
Open the example code from the Arduino Library
There are many preloaded program examples or sketches within the Arduino IDE this is just one you can expand upon. Click on File >> Examples >> CurieImu >> CurieBLEHeartRateMonitor
Wire up your Arduino Circuit
Because we are working with a physical computer, we sometimes need to connect physical elements. Wire up your Arduino as in the picture to the right (Click the image to be taken to the larger image). If you are having trouble, perhaps try the Light Up Harbour Bridge – Beginner Arduino Project as a pre-requisite
To complete this circuit you will need:
- LED x 1
- Resistor x 1 Potentiometer x 1 (and wires or you could use a shield kit)
Upload the sketch to your Arduino board
Upload this sketch to the board by clicking on the upload button. You will need to wait for the green line to fill completely to know your sketch has been uploaded
Download the nRTF Toolbox for BLE App
Visit the Apple or Google Play store and download the nRF Toolbox for BLE App then:
- Open the App
- Select the 'heart' icon (right)
- Click 'Connect'
- Select 'HeartRateSketch'
Turn and Watch
The red LED should now be identifying that you have a Bluetooth connection. Now twist the Potentiometer and see what happens! Magic! Then think of the possibilities! A mood sensor, boredom ranker, 'The worm' in your classroom and so much more!
These are just the basics to getting a handle on the connectivity potential of the Genuino 101 From here you might like to:
- Add a battery pack to make it mobile
- Think of other uses and variables you could measure
- Try connecting other analogue sensors and see what happens Access this site for more information: Intel Innovation Toolbox
