Inside the light is an Arduino Nano, which reads from the ultrasonic sensor mounted underneath the enclosure and lights up the appropriate LED depending on the car’s distance.

Enclosed are the ultrasonic sensor, a temperature sensor and an LED indicating the power status. On the other side of the CAT5 cable can be found an Arduino compatible board with an XBee shield ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

A corridor is a place that really needs lighting. However, it is also one of the causes of energy waste. This study aims to design an automatic switch system in the corridor or hallway of the building ...

Abstract: This paper presents the design and prototype implementation of USenSewer, an automated sewerage management system that uses Arduino microcontroller coupled with an ultrasonic sensor, a NRF ...
