Add ESP32 microservo controller with PlatformIO dependency management

[Copilot]

Overview

This PR transforms the repository into a complete ESP32 project for controlling 4 microservos in a continuous loop pattern. The implementation uses PlatformIO for dependency management and the ESP32Servo library for servo control.

What's New

Project Structure

• PlatformIO configuration (platformio.ini) - Manages ESP32 platform, Arduino framework, and ESP32Servo library dependency
• Main control code (src/main.cpp) - 106 lines of well-documented C++ code controlling 4 servos
• Build exclusions (.gitignore) - Prevents build artifacts and IDE files from being committed
• Comprehensive documentation (README.md) - Complete setup, wiring, and usage instructions

Implementation Details

The servo controller operates 4 microservos connected to GPIO pins 18, 19, 21, and 22. Each servo continuously sweeps between 0° and 180°, creating a smooth looping motion. The implementation features:

• Refactored design - Uses a helper function to eliminate code duplication and improve maintainability
• Configurable parameters - Easy adjustment of sweep speed, angle range, and step size
• Serial debugging - Outputs servo positions every 100 iterations for monitoring
• Proper PWM control - Uses ESP32Servo library optimized for ESP32 hardware

Hardware Connections

Servo	GPIO Pin
Servo 1	GPIO 18
Servo 2	GPIO 19
Servo 3	GPIO 21
Servo 4	GPIO 22

Getting Started

Users can build and upload the code using either:

1. PlatformIO IDE (VS Code extension) - Click build and upload buttons
2. PlatformIO CLI - Run pio run --target upload

The ESP32Servo library is automatically installed on first build via PlatformIO's dependency management system.

Code Quality

• Clean, readable code with proper documentation
• No code duplication - servo update logic extracted to reusable function
• Comprehensive inline comments explaining hardware connections and behavior
• Follows Arduino/C++ best practices for embedded systems

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.registry.nm1.platformio.org
  • Triggering command: /usr/bin/python3 /home/REDACTED/.local/bin/pio run (dns block)
• api.registry.platformio.org
  • Triggering command: /usr/bin/python3 /home/REDACTED/.local/bin/pio run (dns block)
• collector.platformio.org
  • Triggering command: /usr/bin/python3 /home/REDACTED/.local/bin/pio run (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

I want this repository to hold code files and dependency installation for programming a esp32 to control 4 microservos continuously in a loop
