How it works is simple: you can track devices using Bluetooth on the ESP32, and through a combination of presence and signal strength, you can define a sensor that changes to an "on" state when your ...

If you'd prefer to play a game you'd find in an actual arcade, then check out the Galagino. This project combines the power of 3D printing with an ESP32 to create a small arcade cabinet you can use to ...

Two-dimensional (2D) semiconductors with direct band gaps offer opportunities for constructing ultrathin and compactly integrated light-emitting diodes (LEDs). Current LEDs based on 2D semiconductors ...

Fiber-based organic light-emitting diode (OLED) displays have drawn increasing attention due to their inherent wearability and the superior performance characteristic of OLED technology. However, thin ...

Scientists have created tiny disk-shaped particles that can swim on their own when hit with light, akin to microscopic robots that move through a special liquid without any external motors or ...
