At this point, the switching mechanism has already been fully developed and all components were in place, although only on a breadboard. 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 is the heart of the application. As mentioned before, GUIs 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 ESP 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.
