Arduino Traffic Light (Wireless) | #P3

How to create a wireless Arduino traffic light and 3D print a nice case for it. First, I go through the breadboard version, how to make a traffic light on a breadboard, then I go through my design choices (Fusion 360), 3D print all the parts, I use the Creality CR6 SE 3D printer. Quickly show some soldering action, because it's satisfying... Then I go through the full assembly of the traffic light. For the micro-controller, I used the Attiny85, because it's super small, cheap, and is perfect for this kind of simple Arduino projects. To get wireless (WiFi) connectivity, the ESP8266 (ESP-01) was used, which is also small, which is a plus. I used two coin batteries for the power supply, the CR2450, they provide 3V and have a capacity of 550mAh, which is pretty good! When using any battery, you also need a voltage regulator, I used the MCP1700.
