This project is a WiFi-controlled model railway track switch system consisting of:

• a NodeMCU-based track switch (servo + WiFi)
• an Android app to discover and toggle switches
• an optional ESP32 touchscreen controller

🧩 Required Parts

• NodeMCU (ESP8266) (dimensions: 60mm x 31mm)
• SG90 9g servo (dimensions: 23mm x 24.5mm)
• Dupont wire
• Hot glue
• Thin metal wire for servo → track linkage
• the 3D-printed case (duh) - here for both directions there are two versions one is modular and one is standalone - I think standalone is better
• and probably the most important part.. a Piko switch track just like in the image (unless you are willing to edit the model to make another track fit...
