Arduino is a microcontroller designed for real-time hardware control with very low power use. Raspberry Pi is a full computer that runs operating systems and handles complex tasks. Arduino excels at ...

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...

In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever you want, it uses rgb LEDs that are controlled by an Arduino-based microcontroller that ...

LEDs are everything, from some of the largest TV screens you can buy, to the types of bulbs that you use in your home. But, not all LED materials are the same. Some are OLEDs or QLEDs, while others ...

Advanced LED lighting arrays can spectrally tune their output wavelength to highlight different features and defects in captured images. The capability enables a single light fixture to quickly adapt ...

Light-emitting diodes (LEDs) are so ubiquitous that it's easy to forget just how much society relies on these underappreciated technological wonders. Yet, the history of the LED goes back further than ...

Since it began in 2014, Arduino Day has been an annual celebration of creativity, open-source hardware and a thriving community of engineers, developers and makers looking to showcase their latest ...
