The activity was implemented in a primary school. It is a good opportunity to talk about modern living. In new houses or buildings already operating, panels have been preinstalled in order to control radiators, blinds or lights. Many people benefit from controlling their technologies at home with their own smartphones or use a voice controlled intelligent personal assistant. The MIN(K)T learning acitivity support its understanding and combines the basic aspects of electricity and programming.

The activity makes use of the Calliope mini-technology. Students learn how to code in a block programming environment. With a few commands, results are already visible, as the Calliope directly displays something: Tones, LEDs light up, display text, radio. It consists of different sensors (light, noices, temperature, position).

Step one is to illustrate a power circuit. For that students learn how to program a simple if-when-loop.

Step two is the integration of the light sensor and speakers, e.g. the light sensor measures the brightness. Those technologies can be combined with different situations of use.

• Lightsensor: It can be an alarm system if a drawer of a cupboard is opened. It also can be an automatic light switcher which put lights in the room when it’s getting dark. You could also build a simple LED series circuit that switches on when there is movement or increasing darkness. Or music could be played. Or turn on the television.

Also talk about sustainable use (water consumption/electricity/heating), gradually the educator explains the variation of opportunities about the possibility of sensors: light sensor, temperature sensor, light sensor, acceleration and motion sensor, compass and microphone. The educator demonstrates together with students how to program.

• Position sensor: While movement of the house (earth quick) an alarm can ring to protect people.
• Temperature sensor: If it's getting cold, the heating can be turned on.
• Pins: Programming pins means that they could show when plants need water.
• Radio: Two Calliope "communicate" via funk and sending signals to turn on/off electrical devices.

Afterwards students choose two possibilities of programming and start to programm in combination with creating their Smart houses.

Sometimes, educator supported the pupils while programming, providing code snippets to choose from.
