What is ESP32?

ESP32 is a low-cost, low-power system on a chip (SoC) series with integrated Wi-Fi and Dual-mode Bluetooth. Developed by Espressif Systems, it is the successor to the famous ESP8266.

With significantly more power than a traditional Arduino, the ESP32 has become the standard for Internet of Things (IoT) projects, from simple smart sensors to complex web servers.

Why choose ESP32 over Arduino Uno?

If you are coming from an Arduino Uno R3 background, you will find the ESP32 to be an incredible upgrade:

1. Built-in Connectivity: Integrated WiFi and Bluetooth mean you don’t need expensive external modules.
2. Dual-Core Performance: Most versions feature a dual-core 240MHz CPU (compared to Arduino’s 16MHz).
3. Vast Memory: Much larger RAM and Flash memory allow for more complex applications.
4. Advanced Peripherals: Includes touch sensors, hall sensors, DACs, and high-resolution ADCs.
