There are few things as frustrating when you’re trying to get some serious hacking done than intruders repeatedly showing up without permission. [All Parts Combined] has the solution for you, with a ...

A real-time Radar-Based Object Detection System built using Arduino and Processing. Features an ultrasonic sensor mounted on a servo motor to scan 180° areas, mapping distances visually onto a custom ...

The ESP32 is a microcontroller with built-in Wi-Fi functionality, and by using the Arduino IDE, you can handle network communication relatively easily. In the previous article, we explained the ...

Implement a USB PD protocol analyzer, a USB PD trigger board or a more sophisticated power sink using a few additional components and simple Arduino code. Supports several STM32 microcontrollers.

Have you ever been in a situation, whether in a conference room, a private office, or a room in your own home, where you can't tell if someone is inside (or if the light is on) from the outside ...

How microcontrollers and single-board computers coordinate high-speed RF acquisition and generation. How SCPI and UART commands let simple controllers use advanced measurements without FPGA ...

The concept of a 3D scanner can seem rather simple in theory: simply point a camera at the physical object you wish to scan in, rotate around the object to capture all angles and stitch it together ...

What does this project do? A USB camera connected to a Raspberry Pi continuously captures frames. OpenCV encodes each frame as a JPEG and sends it to the CircuitDigest Cloud Face Detection API via ...
