[Arduino Super Introduction #24] Mini Project: Automatic Lighting | Let's Automatically Turn on an LED When It Gets Dark

In the previous chapter, we used a light sensor to read the ambient brightness as a value from 0 to 1023.This time, we will ...

Control LEDs ON/OFF with IR Remote and Arduino

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

Mood Lighting With LEDs And An Arduino

Regular candles can be awfully boring at times. They can only produce one color and the flicker is so… predictable. They can’t even be controlled by an infrared remote control, not to mention the ...

[Arduino Super Introduction #13] Lighting an External LED | Let's Build Our First Circuit on a Breadboard

Last time, we learned about the anode and cathode of an LED, how to distinguish their orientation, and the role of a resistor in limiting current.This time, we will combine an Arduino, a breadboard, ...

Arduino Uno Q In C - Text On The LED Matrix

The 8x13 blue LED matrix is also an example of using PWM to implement gray-level images. The LEDs are connected in a row/column layout in the form of a tree – the first row has one LED pair, the ...

Simplifying Basic LED Effects

There was a time when having a blinking blue LED on a project was all you needed to be one of the cool kids. But now you need something more complex. LEDs should not just snap on, they should fade in ...
