Arduino Round Segment NeoPixel Clock Digital clocks are one of the most popular Arduino projects, and most of them use traditional seven-segment displays to show the time. While these displays are simple and reliable, they usually have the same familiar rectangular shape and monochrome appearance. When I decided to build a new digital clock for my room, I wanted to create something that worked like a seven-… |

Life-Sized Animatronic Goddard Robot Maker and YouTuber Kiara from Kiara's Workshop recently created an impressive, fully functional real-life version of Goddard, the iconic robot dog from the cartoon The Adventures of Jimmy Neutron, Boy Genius. The robot dog features moving parts, including corrugated tube-like legs that compress using four linear actuators mounted inside them, a cable-driven neck that can look up/down and turn… |

DIY LEGO RC WALL-E Robot Using ESP32 and a PS4 Controller The main part of the project is a LEGO RC WALL-E itself. He initially planned to use a FlySky controller and its remote, but later switched to a PS4 controller as it is much more compact and offers more controls. He used an ESP32 as the receiver. After some research, he decided to use the Bluetooth functionality of the ESP32 for communication. Two N20 motors along with an L298N motor driver… |

Reticulum : A Decentralized Networking Stack A recent project showcases Reticulum, a cryptography-based networking stack designed to build a decentralized, infrastructure-independent communication network. Unlike traditional mesh systems that depend on specific radios sharing the same frequency, Reticulum abstracts hardware into interchangeable “interfaces.” Whether the link is LoRa, Wi-Fi, Ethernet, or packet radio, the protocol… |

LiteWing Flight Positioning Module NeoPixel Status Control (WS2812B) In this guide, we focus on the WS2812B addressable RGB LEDs on the LiteWing Flight Positioning Module. The module includes four NeoPixel-compatible LEDs, each independently controllable via software. These LEDs are useful for flight status indication and visual debugging during development. A curated collection of hands-on drone projects with guides showing how to… |

Driving NeoPixel LEDs Using Pure Hardware - No Microcontroller, No Code A recent video by Axiometa explores an unusual electronics challenge: driving addressable NeoPixel LEDs entirely in hardware, without any microcontroller or code. Since WS2812-style LEDs normally rely on tightly timed digital data from MCUs, the project asks whether basic components like counters, timers, and logic gates can replicate the protocol. The goal was to generate the required pulse… |

Smart Home Automation By Ashish Spolia The rapid evolution of the Internet of Things (IoT) has transformed the modern household from a passive living space into an intelligent, responsive ecosystem. As safety concerns and the demand for convenience grow, there is a critical need for integrated systems that can monitor environmental hazards, provide robust… |

DIY Arduino Bluetooth Car Controlled by Mobile Application For many years, robots have been a popular topic among students, hobbits, and DIYers. If you are a beginner and enjoy building robots, this is likely the first project you will do after learning the basics, which is why we decided to build a Wireless Bluetooth Controlled Robot Car Using Arduino. This robot car can be… |

Build Digital Cracker using Arduino and JQ6500 MP3 Module As the winter season approaches, comes the festival of lights in INDIA. Yes, we are talking about Diwali, known for lighting up firecrackers. But they don't just light up the party; they also cause air pollution and bring health issues. So, to reduce pollution and improve our health we decided to build an Electronic Firecracker using Arduino which makes a loud sound… |

Interfacing WS2812B Neopixel LED Strip with Arduino When you require a dynamic lighting solution, LED strips are a great choice. They may be mounted almost anywhere, available in a variety of colours, and require very little maintenance. Finding another lighting system that offers as much value and style would be challenging. And even this standard is raised to a completely new level by… |

Yet Another Arduino Digital Clock, but It’s Unique and You Will Need It I know making a clock sounds a little irrelevant, especially nowadays because we all have smartphones and no one is going to use or look into the clock for time, but it is good when you are doing some work or during the workout. So, I decided to make one Arduino digital clock for my room. While searching for the clock model, I got thousands of designs but most of them were… |

How not to Build a POV Display Using WS2812B Neopixel LEDs and ESP8266 For one of our projects at circuit digest, we wanted to build a Persistence of Vision Display or POV display with WS2812B LEDs. While making the project, our only focus was on how we could make it simpler along with less hardware. As a result, we chose some simple WS2812B RGB LEDs and an ESP8266-01 as the brains for this project because they are lightweight … |
