This project implements a motion-sensing app-controlled single-axis pet toy on Arduino-based firmware and a Blynk-based frontend.

• ESP8266 or ESP32 microcontroller, like a Wemos D1 Mini
• Passive infrared sensor, like the ubiquitous HC-SR501
• Blynk
• Wifi connection
• Platformio (optional for dependency management)

1. Wire up the circuit like this (or check out the pin config in the code and wire it up according to your components)
2. Configure your Blynk app like this
3. Modify include/config.h with your secrets
4. Compile and upload the firmware
5. Tune your servo settings in the constants at the top of main.cpp
