My First Electronics Project - Building a Real-Time Power Outage Monitor with ESP32 and Slack

This article details the author's first electronics project: creating a real-time power outage monitor using an ESP32 microcontroller and Slack webhooks. It covers the hardware stack including ESP32 DevKit V1, USB-TTL converter, and capacitor for inverter switchover. The author explains solving electrical noise with grounding geometry and software debounce to prevent false alerts. The project is non-invasive, resilient, and sends instant Slack notifications when grid power fails. Includes links to a documentary and GitHub repository. A practical, tech-focused tutorial for IoT and home automation enthusiasts.
