This project is a smart water level controller built using Arduino UNO, an ultrasonic sensor, and EEPROM for memory storage. The system automatically monitors the water level in a tank and controls ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

“Part Fill” Valve? Yes, Part Fill valves are widely used in Rainwater tanks. The valve will open once the water level in the tank has fallen to a low position, this allows the town mains water to ...

In Texas — at least around Houston — we don’t have basements. We do, however, have bilges. Both of these are subject to taking on water when no one is paying attention. A friend of mine asked me what ...

今回は、Arduinoで超音波センサーを使って距離を測る方法についてご紹介します。 超音波センサーは触らずに物体との距離を測ることができます。 応用すれば、「物体が一定の距離まで来たら停止する」という動きをロボットにさせることもできます。
