APA102 vs SK6812 – Which LED strip to use?

Going online in search of a LED strip, be it for a prototype or school project, you may be seeing a huge variety of LED strips, ranging from different functionality and price tags. With so many types of LED strips...

Scrolling text with flexible 32×8 RGB LED Matrix

Needed a way to display scrolling text or messages? This Flexible 32×8 RGB LED Matrix display may suit your needs! With 256 LEDs on it, you can display text, patterns or even animation if you want to. Therefore, in this tutorial,...

Simple Electronic Compass

This is a simple electronic compass display project, which uses the HM55B compass module to determine the North direction. The LEDs will be used to indicate where North is. When the module is facing north, the specific LED that is facing north...

Controlling RGB LED using Bluetooth Bee

This project uses the Arduino Uno board and a bluetooth bee. In this project, the RGB LED on the breadboard is controlled using a phone via bluetooth terminal, where different input changes the color of the RGB LED.

LED switcher using a DPDT Relay and a potentiometer

In this project, 2 LEDs will be switched on and off using the DPDT relay. (or flip-flopping the LEDs) This is another simple project to further explore the features of Arduino.

Arrays with a 7-segment LED display

This is another project using Arduino Uno. In this project, I used a 7-segment LED display to loop the digits 0-9 using array though there are still some bugs in the program.

Light intensity indicator with 7-segment LED display

This is similar to the other light intensity indicator tutorial. In this tutorial, the 7-segment LED display will be used to display the intensity of the light received by the photo resistor, mapping the light intensity values from 1 to 9.

LED Light intensity indicator

This is a simple light intensity indicator using a photo-resistor and 3 LEDs. It indicates the amount of light available around the photo-resistor with a range of 3 LEDs. Arduino UNO board will be used in this tutorial.

Simple LED light chaser

In this tutorial, you will learn how to make a simple light chaser, which will consist of only 3 LEDs. What does a lightchaser do? A light chaser can be used to create lighting animation sequences to attract attention.
