This project demonstrates an Automatic Water Level Controller using an Arduino Uno, HC-SR04 ultrasonic sensor, a relay module, and two push buttons. The ultrasonic sensor measures the distance from ...

Ultrasonic Sensor: An ultrasonic sensor is used to accurately measure the distance to the vehicle ahead, feeding real-time data to the PID controller. Arduino-Based Implementation: The system is ...

By the way, we’ve covered a PID library for Arduino before. While this post talks about temperature, PID control is used for everything from flight control to levitation.

At Maker Faire Milwaukee this past weekend, [basement tech] was showing off his latest build, a PID controlled charcoal grill. While it hasn’t QUITE been tested yet with real food, it does w… ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Control Engineering is at the heart of almost every modern technology, from robotics to home automation, and now, with the help of Arduino, ESP32, and RP2040, it’s more accessible than ever. In " ...
