Using electronic devices (such as Arduino™)

Even if it is your first time with electronics, you could easily follow this tutorial.

Just buy an Arduino™ Uno kit, and connect a potentiometer like in this tutorial. Note that you do not need to program your Arduino™, just build this simple circuit.

1 / Connect your Electronic Device

To connect an electronic device to Millumin, open the device manager (CMD+K) and go to electronic. Then, click on the + button to create the adequate device :

Millumin support the following devices :

  • Arduino™ Uno
  • Arduino™ Mega ADK
  • Arduino™ Mega 1280
  • Arduino™ Mega 2560
  • Teensy 3.2

Once you have created the correct electronic device, select the USB serial :

Then your electronic device will be connected to Millumin automaticaly. If the device is already well programmed, it is ready to use as Interactions or as a Data-track in Millumin.
 Take a look at the dot on the right. If your device is correctly connected, it should be green. The same occurs for the active checkbox that should be checked.

2 / Auto-program your Electronic Device

Millumin offers an interface to program your electronic device with ease.
 Select your device in the electronic device panel, and click on the auto-program button :

 Then click on the + button to create the pins you need to use (you can create up to 63 ones) :

The key is the name of the pin you want to configure. It matches what is written on the electronic card. The type is the type of interaction the pin has to handle :

  • IN : sensor (such as infrared sensor or potentiometer)
  • PULLUP : sensor that needs a pull-up resistor (typical use for a push-button)
  • OUT : to send a value to your pin (to switch on a LED for example)
  • SERVO : for a servo-motor
  • OFF : no behaviour (please note that all pin are off by default)

Once you finished the pin configuration, click the upload button. Millumin will automatically program your electronic device :

When running the upload for the first time, Millumin will need to install some dependencies. To do so, it will ask you for administration privileges.

Note that if you are running an old computer, you might need to install Python 2.7.10. If so, Millumin will ask you to download the last version of Python here.

Once the process is finished, your electronic device is ready to work with Millumin.

3 / Debug your Electronic Device

To test it, look at the signal column. Input pins display a dot : if green, the pin is working correctly, if red it is obviously not.

Output pins, like OUT or SERVO, have a test button that send data to the pin. If you have connected a LED, it will turn it on then turn off. For a servo-motor, it will make it rotate.

You could also open the Monitor to display all values coming from and to the electronic device.

Go to the menu bar, click on Window then select Monitor :

4 / Manually Program your Electronic Device

If you want to manually program your device, we invite you to explore our developer-kit .

Please use those libraries for better work between your device and Millumin.
 We encourage you to use the PlatformIO IDE to program your electronic device.

Look at those sample codes to understand how to program your device with the MilluminStream library.
 For a better understanding of the library, read : MilluminStream.h
