Furthermore, by temporarily decoupling the switch from the circuit of the object to be turned on or off and putting a microcontroller in between, the (automated) system becomes capable of utilizing the acoustic, visual and haptic signals evoked via the usage of its interface to articulate intent (at least this is the hypothesis to be confirmed). To conclude, my thesis is about designing output gestures made of sequences of clicks in combination with flickering lights as means of communication. To do so a conventional switch is being equipped with some more advanced technology, and that is what this project is about. | Furthermore, by temporarily decoupling the switch from the circuit of the object to be turned on or off and putting a microcontroller in between, the (automated) system becomes capable of utilizing the acoustic, visual and haptic signals evoked via the usage of its interface to articulate intent (at least this is the hypothesis to be confirmed).

At this point, the switching mechanism was fully developed and all components were in place, although only on a breadboard. As mentioned before, I would have installed all the technical components on the back if it hadn't been for the idea of realising the backend as a frontend. So the transfer to a PCB was the next logical step. | |||

In contrast to GUIs, that can be altered by simply changing bits from zero to one or vice versa, altering objects of the physical world requires kinetic energy. Therefore an electromechanical transducer is necessary. After many experiments, the decision was finally made in favour of a 12V DC brushed gearmotor. To control it with a microcontroller the L9110S H-bridge driver IC has been chosen. As the project is rooted in the smart home milieu, the decision on a microcontroller was easy: An ESP12 module based on the famous ESP8266 chip by espressif. As it runs on 3.3V a regulator IC (12V to 3.3V) was also to be installed as well as a couple of resistors, capacitors and buttons. | |||
