This project uses an ESP32 and R503 fingerprint sensor to register and verify users, showing scan status on an OLED and updating a Wi-Fi-hosted dashboard that tracks attendance entries and exits, manages fingerprints, and offers CSV export for attendance data.

Plug four Modulino sensors into your Arduino UNO Q, run the Arduino App Lab, and open Pure Data to transform it into a live drum machine and polyphonic synthesizer. The UNO Q reads your gestures and runs the audio software simultaneously.

Explore the process of designing a custom PCB and schematic for the CH32V003, a 10-cent RISC-V microcontroller, including manufacturing file preparation and SMT ordering at JLCPCB. This design aims to test the MCU's use in capacitive touch sensing.

Combine multiple sensors with the ESP32-S3 Smart Display to create a single device that continuously measures and displays temperature, humidity, pressure, altitude, rain status, and day/night detection through a dynamic LVGL graphical interface.

The ESP32-C3 Super Mini offers full ESP32 power in a tiny package but sometimes loses Wi-Fi and Bluetooth connections unexpectedly. Here are three reliable fixes that address this common problem caused by hardware and software factors.

This update transforms WLED into a powerful platform with dynamic preset transitions, particle effects, and advanced matrix features. You can now play animated GIFs, design custom fonts, and use PixelForge for pixel graphics, plus enjoy improved stability on ESP32 devices.

This project uses a beam splitter cube and two OLED displays controlled by a Wemos D1 Mini to create a holographic display that lets two people see separate images at the same time from opposite sides.

Combine a Raspberry Pi with motionEyeOS to build a remote surveillance camera that’s easy to customise, supports multiple units, and lets you watch live or recorded video from desktops and mobiles.

This open-source device lets you monitor and control SPI, I²C, UART, CAN, and analogue signals wirelessly through a browser, removing the need for separate adapters or software.

This cyberdeck build centres on a Raspberry Pi Zero 2W for wireless connectivity and low power use, paired with a tiny keyboard and a 7-inch display, all running off a hefty 4000 mAh battery and bundled into a custom 3D printed case.

Using dToF technology, the LiDAR sensor collects 360° distance profiles, which feed into an Edge Impulse-trained model running on the Arduino UNO Q for real-time, low-latency room detection without complex mapping methods.

This ESP32-based CYD board comes with a bright 2.8-inch colour touchscreen and built-in Wi-Fi to display real-time stock and crypto prices. You configure it via a browser on your network, and it updates automatically, lets you tap tickers for details, track your portfolio, and signals price alerts with an LED.

With affordable parts and straightforward coding, you can build a neat Pomodoro timer powered by an ESP32 that sits low on your desk and lets you adjust focus and break lengths via a touchscreen. The project files are all open-source on GitHub for easy setup and personalisation.

This project shows how to create a Wi-Fi camera using the ESP32-CAM that captures images from a web dashboard, controls the flash, and uploads photos directly to Google Drive. It uses free Google services to keep things simple and accessible from any device, no extra cloud setup required.

Learn how to make HTTP GET calls from an ESP32 using ESP-IDF and parse JSON responses from external APIs like TimeAPI.io.
