When you take your phone in sunshine or in high lighting, then it automatically adjusts the brightness according to the lighting conditions. Most of the display devices now a days, whether it’s a TV ...

Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. [Udo] hit upon the idea of pulsing a laser pointer and measuring the time of the ...

The sensor has 3 wires RED, YELLOW, and BLACK as shown in the figure below. The red wire is used for supply voltage which ranges from 5V to 18V and the black wire is ...

Abstract: This article presents the design and application of an Arduino UNO-based system incorporating nine red Light Emitting Diodes (LEDs) and a temperature and humidity sensor (DHT22) for research ...

Abstract: Transportation serves as a means of connecting and has a very significant role in the movement of goods and people. Road transportation as connectivity between regions in urban areas, has ...

This Arduino-based project simulates a Formula 1 race start light system and measures the user's reaction time using an ultrasonic sensor. Instead of pressing a button, the user waves a hand to start, ...
