A laser security alarm stands out as a highly effective system designed to detect any object or individual’s presence. Within a designated room, multiple laser beams are often employed. Reflective mirrors are commonly utilized to create a laser grid. When any object intersects these beams, triggering contact with the laser, the alarm system activates instantly. […]

This project demonstrates building a real-time clock (RTC) with temperature display using an Arduino, DS3231 RTC chip, and SSD1306 OLED display (128×64 pixels). The DS3231 RTC chip provides more accuracy than the DS1307 and incorporates an onboard temperature sensor. It maintains timekeeping even without the main power, making it well-suited for this application. It communicates
Wise Clock 3 is an open-source, highly hackable geeky clock that shows a lot more than the time. Its main function is to display user-editable quotations retrieved from an SD card (like those used in photo cameras). In addition, Wise Clock 3 can show the time in “Pong” mode or “Pacman” mode. It can also

Ever since my addressable RGB LED strips (WS2812B) came from Aliexpress, I’ve been fascinated with LED projects. Following up on my success with my Charlieplexed LED clock, I wanted to create something with more Jazz.. While browsing google images, I came across an instructable for an Arduino Infinity Mirror and the brain cells started working

This project is a small game you can play with another player. You can time your reaction speed and compete with your friend. The game is inspired by the start lights of a formula 1 race. Earlier Iterations: The images above are of earlier iterations of certain components and the casing. In the original idea,

Project and Instructable write-up done by Ian Lacy on behalf of the MIT Edgerton Center. In this project, I’ll show you how to build an Apollo 11 clock. The clock has each hour associated with a leg of the mission, and plays an associated audio clip at each hour. Every third hour, it also has a

Please vote for me in the contests i have entered. Hope you enjoy the instructable, and happy making. I was, some time ago, quite interested in IoT projects and so I thought it would be fun to make something associated with the Internet. I recently purchased the micro-controller called the nodeMCU and it’s superb. After having decided
