The Distance Monitoring System with LED Feedback is an Arduino-based project that utilizes ultrasonic sensors, LEDs, and an LCD display to create a real-time distance measurement and visual feedback ...

About This Arduino project controls a servo motor based on distance measured by an HC-SR04 ultrasonic sensor, adjusting to four angles for different proximity ranges. It updates only when significant ...

This project is a simple modification of the LightGauge project. Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino.

We’ve featured a lot of Arduino projects focused on the indoors and home automation in the past, with outdoor builds being more difficult to come by. When we do find them they’re usually worth ...

Half of the population was impacted by the coronavirus last year, and the number of cases is still rising daily. Direct and indirect contact with infected people is how COVID-19 spreads. This paper ...
