Best ESP32 Projects to Start Today
The ESP32 is the most versatile microcontroller for DIY electronics. Here are our top 5 beginner-friendly projects that will teach you WiFi, Bluetooth, and IoT skills while building something cool.
1. WiFi Scanner
Build a simple WiFi network scanner that displays all nearby access points, their signal strength, and encryption types. This teaches you WiFi basics and the ESP32 WiFi library.
2. Bluetooth Sniffer
Scan for Bluetooth devices in your area. Great for understanding BLE advertising packets and device discovery.
3. Web Server Temperature Monitor
Connect a temperature sensor and serve the readings on a web page. Learn about HTTP servers and sensor integration.
4. RFID Card Reader
Use an RC522 or WS1850S module to read and write RFID tags. Essential for learning about access control systems.
5. Sub-GHz Signal Detector
With a CC1101 module, your ESP32 can detect 433MHz and 868MHz signals from remote controls and sensors.
