You can control the brightness of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Here, the three LEDs are directly connected to Arduino pins with independent current limiting ...

Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full ...

Software scalability is also supported on the new board, allowing easy upgrades for projects made with UNO R3 or Leonardo. Requests from the Arduino community see the USB port upgraded to USB-C ...
