MQTT WiFi controlled mains halogen dimmer

The mains part with the triac is now built on perfboard. Works fine. A small reallife test showed that it also works on the 300W halogen transformer. Had to pull an extra nullwire as it wasn't present at this location.

Learning how to use Fritzing in order to create a small perfboard to test the high-voltage part on the 300W halogen lamp.

Got the ESP-102 to work with Arduino IDE. Now make it speak to the PIC at 9600 baud.
