ESP32 Development

The ESP32 is Espressif's low-cost, high-performance microcontroller with built-in WiFi and Bluetooth. It's ARM-based, runs at 240MHz (fast for IoT), and costs $5-15 per unit. Unlike Arduino Uno (no WiFi), ESP32 connects to networks natively. ESP32 firmware can be written in C++ (Arduino IDE or ESP-IDF) or Python (MicroPython). This makes it accessible to developers of varying skill levels. Applications include smart sensors (temperature, humidity, light), wearables (fitness trackers), home automation (smart lights, door locks), and industrial monitoring.
