This project uses an Arduino Uno and a DHT11 temperature and humidity sensor to monitor ambient temperature in real-time. The system displays temperature readings on the serial monitor and triggers an ...

The past month or so I’ve been playing with the Maxim DS1307 Real-Time-Clock and DS1621 Temperature Sensor ICs. I hooked them up to an Arduino Uno board with a Parallax Serial 16×2 Character LCD. I ...

ネコちゃんと暮らし初めて、とにかくご機嫌に遊んで過ごしていただきたいと考えるようになりました。毎日誠心誠意ねこじゃらしを振るのに加え、ご自身でも遊んでいただけるものを捧げたくなり、フルカラーLEDテープを使って、センサーで感知すると光 ...

[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using ...
