Getting Started with ESP32-P4X-EYE: ESP32-P4 Vision Development Board Vision development boards are useful when an embedded project needs to combine image capture, local display, audio input, storage and wireless connectivity in a single platform. The ESP32-P4X-EYE takes this approach around the ESP32-P4, adding an ESP32-C6 wireless module, a 2MP MIPI-CSI camera, a 1.54-inch SPI LCD, a digital microphone, MicroSD storage, USB… |

How to Build an IoT-Based Parking Space Detection System Using Raspberry Pi and CircuitDigest Cloud Everybody likes weekends. On weekends, you often drive with your family to crowded places like malls, theme parks, or circuses for outings and relaxation. But then comes one of the most frustrating parts of the trip: searching for parking. Sometimes, finding a parking space feels even harder than waking up early in the morning.Even if there is a security guard or… |

How to Make a Raspberry Pi Waste Segregation System Using CircuitDigest Cloud Running, running, every day, we keep running to work, school, and college. In this busy routine, many of us do not even have enough time to eat breakfast properly. Then where do we find the time to clean our homes? Even when we clean, because of laziness or lack of time, we often throw all waste into the same bin without separating biodegradable and non-biodegradable waste. This creates a… |

How to do Object Detection with Raspberry Pi Using CircuitDigest Cloud What if a device could see the world the same way humans do, seeing objects, recognizing them, and understanding what they are in real time? Just like our eyes capture visuals and our brain instantly processes them, from bottles and phones to people and everyday items. It will be pretty cool, right? That is exactly what this Raspberry Pi object detection project demonstrates. You can build a… |

How to Build Helmet Detection with Raspberry Pi Using CircuitDigest Cloud As adults, it is our duty to follow traffic rules, and the most important rule is to wear a helmet while riding a two-wheeler and not to cross the speed limit. It's not a rule, but it's also for safety. Now, let’s think from the traffic police officer’s side. Their duty is to monitor traffic and check whether everyone is following the rules, but it is quite difficult for a traffic officer to… |

How to Build a Face Detection System Using a Raspberry Pi and CircuitDigest Cloud When we see movies, we often see scenes where a villain uses a gun with a face detection system that automatically targets a person accurately. It may look like a very complex technology that is difficult to build on our own, right? Not anymore. Building a face detection system using a Raspberry Pi might sound like something out of a Hollywood thriller, but it… |

Engineering a Functional Arm Cannon for the Makers of Halo A maker built a real, functional replica of the arm cannon belonging to Vandal, a character in Bungie's video game Marathon, for use in a commercial. The builder had 18 days to complete the entire project. The build was divided into two main subsystems: a forearm clamshell mechanism and an internal barrel assembly. Bungie provided game asset mesh files for reference but, because the… |

Automatic Waste Segregation System Using Arduino UNO Q Proper waste sorting is very important for keeping our neighbourhoods clean and saving resources for the future. When we mix food scraps, plastic, paper, and batteries in the same bin, recycling becomes hard, landfills fill up quickly, and harmful chemicals leak into the soil and water. Over time, this creates bigger problems like higher cleanup costs and more damage… |

Algorithmic Robotic Golf Club Masters Complex Mini-Golf Shots Engineer and creator Shane Wighton has upgraded his robotic mini-golf system to tackle complex, physics-heavy shots with near-perfect accuracy. The project combines a motorized golf club with a full motion-capture setup, allowing the system to precisely track the ball, club, and course geometry. By scanning real-world mini-golf layouts into a digital model, the system can analyze terrain… |
