Tutorial: How to Use ESP-32S

The ESP-32S is a versatile development module supporting WiFi and Bluetooth. Useful for IoT projects and wireless applications.

What you need

• Arduino IDE
• USB cable
• PC with Windows 10 or higher

Steps

1. 1. Download and install the Arduino IDE.
2. 2. Connect the ESP-32S to the PC via USB cable.
3. 3. Select ‘ESP32’ as board and ‘ESP32 Dev Module’ as port.
4. 4. Load the example code ‘Blink’ to control the LEDs.
5. 5. Connect the ESP-32S to WiFi using the ‘WiFiScan’ code to find your network.
6. 6. Try to send data to an MQTT server with ‘PubSubClient’.
