You can control the brightness of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Parts Needed Arduino UNO board – 1 5mm LEDs Red, Green, Blue – each 1 100K Variable resistor – 3 1K ...

Each circuit can have a lot of useless components just for the story-telling but the only thing that really matters is its resistance (the only really connected components are resistor (s)). Each ...

This repository contains list of my pet Arduino projects, specially developed to learn about electronics, circuits and C++ programming. - giaongo/Arduino-Projects ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

Also, a series resistance has the disadvantage of power loss through the resistor. A better option is to use a suitable dc/dc converter. If the LED’s turn-on voltage is lower than the battery voltage, ...
