FAQ

Q: Can I use an Arduino Uno instead of an ESP32?
A: While possible, the Arduino Uno lacks built-in Wi-Fi. You would need an external module like the ESP8266 or an Ethernet shield, making the ESP32 a much simpler and more powerful choice for IoT.

Q: Is it safe to control AC appliances?
A: Controlling mains voltage (110V/220V) can be dangerous. Always ensure your circuits are disconnected from the mains while wiring, and use properly rated relays and enclosures.
