Discover Arduino Projects
Hundreds of projects from beginner to advanced — schematics, code, and videos.
Led Lighting
Basic input project that turns a single LED on and off at regular intervals with Arduino. Teaches the use of digitalWrite and delay functions.
2 Led Lighting
Project that creates a flip-flop effect by sequentially turning on and off two LEDs. Teaches how to control multiple output pins.
Traffic Lamp
Project that simulates a real traffic light with red, yellow and green LEDs. Teaches timing and sequential control logic.
Police Lighter
Project that creates a police strobe light effect by flashing two LEDs at fast intervals. Teaches for loop and timing control.
Walking Led
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.
Karashimşek Led
Project that creates a Knight Rider style black lightning effect by lighting 6 LEDs in a back and forth sequence. Teaches bidirectional loop logic.
Speed Adjustable Walking Led
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.
Speed Adjustable Led Black Lightning
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.
Led Burning with Push Button (Push)
Push control project that turns on the LED when the button is pressed and turns it off when it is released. Teaches button reading and conditional expression usage with digitalRead.
Led Burning with Button (On Off)
A toggle project that changes the state of the LED (on/off) with each button press. Teaches state variable and debounce logic.
Reading Light Intensity with Ldr
Project that measures ambient light intensity with LDR sensor and displays it on Serial Monitor. Teaches the basics of analog sensor reading and serial communication.
Night Light with Ldr
LDR based night light project that automatically turns on the LED when the environment gets dark. Teaches automatic control logic with analog threshold comparison.
