+# mata avispas
+
+Flyback high voltage generator (≈12 kV output) controlled by an ESP32‑C3.
+
+Features
+- ESP32‑C3 runs as a Wi‑Fi Access Point (AP) so you can connect directly to it.
+- A simple web server lets you adjust the PWM frequency/duty cycle that drives the XY‑MOS driver.
+- PWM output is generated on a GPIO using the LEDC hardware (high‑resolution, glitch‑free).
+- Safety: the PWM can be disabled via the web page.
+
+Hardware notes
+- XY‑MOS driver expects a PWM signal (typically 5 V logic) on its INPUT pin.
+- Connect ESP32‑C3 GPIO to XY‑MOS INPUT through a level‑shifter if needed (ESP32‑C3 is 3.3 V tolerant, most XY‑MOS accept 3.3 V).
+- Flyback transformer secondary should be properly insulated and terminated with a high‑voltage diode/Cockcroft‑Walton multiplier if you need DC.
+- Always use proper shielding, grounding, and never touch the output while powered.
+
+How to build
+1. Install the ESP32 Arduino core (Boards Manager → esp32 by Espressif Systems).
+2. Select "ESP32C3 Dev Module" (or your specific board).
+3. Copy this folder to your Arduino sketchbook or open with PlatformIO/VSCode.
+4. Compile and upload.
+5. After upload, the ESP32‑C3 will start an AP named `MataAvispas_AP` (password `avispas123`).
+6. Connect your phone/laptop to that AP, open a browser to `http://192.168.4.1` and adjust PWM.
