Version 2 of the Photogate — implemented with ESP-IDF v5.4.2 for an ESP32-based photogate project.

---

Overview

This is the second version of the Photogate project, featuring significant improvements in accuracy, reliability, and visual interface, along with available 3D models and schematics. : Designed for educational and experimental applications using the ESP32 platform.

---

Requirements

• ESP-IDF v5.4
• A configured ESP32 development environment (terminal toolchain)
• Required cables and hardware to flash the firmware

---

Build and Run

1. Clone the repository:

   git clone https://github.com/marciobulla/photogateV2.git
   cd photogateV2

2. Set up the ESP-IDF environment
   Follow the Get Started with ESP-IDF guide.

3. Build, flash, and monitor:

   idf.py build flash monitor

   This will compile the project, upload it to your ESP32, and open the serial monitor.
