Throttle Box

An ESP32-based project to control a servo motor with smooth, randomized movements. Designed for physical interaction simulation or anti-idling purposes.

Features

• Precise PWM Control: Uses microsecond pulse widths for fine-tuned servo travel.
• Smooth Easing: Implements a Smoothstep algorithm ($3t^2 - 2t^3$) for fluid, lifelike motion.
• Continuous Randomness: Moves directly between random positions in a configurable range.
• Plotter Support: Streams numeric pulse data compatible with the Arduino Serial Plotter.

Hardware Support

• Target: ESP32 (e.g., NodeMCU, DevKit).
• Pinout: Signal connected to D18.
• Driver: Requires Silicon Labs CP210x USB to UART Bridge drivers on Windows.

Configuration

At the top of main/main.ino, you can adjust the following:

• minPulse: Minimum pulse width (default 1000us).
• maxPulse: Maximum pulse width (default 1800us).
• minWait: Minimum wait time (default 8000ms).
• maxWait: Maximum wait time (default 25000ms).
• moveDuration: Duration of each transition (default 2000ms).

Setup

1. Open the project in the Arduino IDE.
2. Install the ESP32Servo library.
3. Select your ESP32 board and COM port.
4. Upload and monitor via the Serial Plotter (115200 baud).
