Hundreds of projects from beginner to advanced — schematics, code, and videos.
Project that creates a walking light effect by lighting 6 LEDs in sequence. Teaches the use of array and multiple pin control with for loop.
Project that creates a Knight Rider style black lightning effect by lighting 6 LEDs in a back and forth sequence. Teaches bidirectional loop logic.
Project that can adjust the LED walking speed in real time with the potentiometer. Teaches to dynamically control the delay time by reading the potentiometer value with analogRead.
Project with potentiometer that can adjust the speed of the black lightning LED animation in real time. It combines analog input and bidirectional loop control.
IR control project that can independently turn on/off 3 LEDs with different keys of the remote control. Teaches how to match remote control codes and control multiple outputs.
A project for one-way data transfer between two Arduinos via serial communication. It detects the button press on the transmitter side and teaches to control the LED on the receiver side.
A project that transfers data bidirectionally between two Arduinos via serial communication. Both boards both read buttons and send data and receive data and control LEDs.
Control project that lights LEDs in 4 different directions according to the X and Y axis values of the joystick module. Teaches analog joystick reading and direction detection logic.
Project that can turn 3 LEDs on and off independently with 3x4 keypad keys and perform batch control. Teaches multiple output control with keypad.
Project demonstrating the basic use of the WS2812B addressable LED strip by adjusting the color of each LED independently. Teaches pixel-based color control with the FastLED library.
A project that creates a police strobe effect by rapidly flashing red and blue colors with WS2812B LED strip. Teaches group-based LED control and animation timing logic.
Project to create a walking light effect by sequentially moving a single LED forward in a WS2812B LED strip. Teaches pixel-based sequential animation logic.
