Comparing ESP32 and Arduino Uno in IoT Projects
1. What is Arduino?
Arduino is an open-source electronics platform based on easy-to-use hardware and software. It’s designed to make electronics more accessible to artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.
2. What is ESP32?
ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth (classic and BLE) capabilities produced by Espressif Systems.
3. Arduino vs ESP32: Detailed Comparison
3.1. Processing Power
Arduino Uno: 16MHz clock speed, 32KB RAM
ESP32: Up to 240MHz clock speed, 520KB SRAM & 4MB Flash
3.2. Connectivity
