Dollhouse with IoT Sensors: Party-Activated Disco Ball, Temp & Lighting Control, even a Burglar Alarm! | #IoTuesday

Dollhouse of Things?!

This is an absolutely remarkable project by Ivo Pullens – complete with thorough documentation and pictures on the MySensors website (after it was exhibited at the Eindhoven Maker Faire earlier this year).

I specifically designed a sensor node for the dollhouse. It is spread throughout the house, small enough not to disturb the looks of the dollhouse. This sensor node is basically an Arduino Pro Mini with an SMD nRF24L01+ radio and a CR2032 battery holder. You can build your own, or build a setup using a regular Arduino.

Some remarks upfront:

  • Due to the large amount of sketches and sensors I will not be able to update the sketches or hardware designs when libraries change or hardware becomes obsolete.
  • The dollhouse sketches are shared on my github page
  • Make sure all required libraries are installed, which are described in the readme. The exact SHA of each library version I used for compilation is included, so if you run into troubles try these exact version first!
  • I use a small ‘library’ called DemoSensorConfig which is shared by all sketches. It contains the MySensors network configuration, node ID’s and some LED blinking code in a single location. To run a sketch standalone only the relevant parts from DemoSensorConfig have to be copied to the sketch (replace the DemoSensorConfig #include).

Among the many technological upgrades and features to this dollhouse are a wind sensor:

A television set whose unit appears ‘plugged in’ to the wall behind it:


A voice-controlled fireplace:

And yes even a ‘toilet node’ with motion-detected capabilities for flushing the loo:

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
