This ESP32 project is an exciting and interactive way to control LEDs using hand gestures. We will use an ESP32 board, Python, MediaPipe, and OpenCV to create a system that can detect specific hand ...
This project demonstrates controlling multiple LEDs using a 74HC595 shift register driven by a 555 timer. The 74HC595 allows for efficient expansion of output pins, letting you control multiple LEDs ...
Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...
