H0 Piko Track Switcher (using Android Phone)
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
š§© 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 ā 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...
