Raspberry Pi Is Getting a Snap-On 5V Logic Level Shifter with bPiShift A hardware add-on called bPiShift is on its way to simplify voltage level shifting for Raspberry Pi users. It’s a compact and solderless solution that snaps directly onto the 40-pin GPIO header of your Pi. This tool lets you interface your Raspberry Pi with 5V peripherals like sensors and serial devices, removing messy jumper wires or separate logic converter boards from the equation. … |

Hand Gesture Recognition using ESP32 and Python 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 gestures and translate them into actions that control LEDs. MediaPipe will be used to recognize the hand gestures, while OpenCV will capture the real-time video feed from a webcam. Based on the… |

Adding GPIOs to Any Computer Using USBgpio You might be wondering why the Raspberry Pis are so popular despite there are desktops or laptops that are much more powerful than a Pi. Apart from the small form factor and low power usage one of the major advantages is the availability of the GPIOs. With that, we can integrate them into any project from bare minimum to advanced robotic projects. So why can’t we use… |

ESP32 Interrupt Tutorial Interrupts are used to handle events that do not happen during the normal execution of a program, but when a specific trigger occurs. For example, if we write a program to blink an LED, the microcontroller will execute each command one by one. But if we want to monitor a switch to start or stop the blinking, it will only be possible after all other tasks before the… |
