Hundreds of projects from beginner to advanced — schematics, code, and videos.
Basic input project that turns a single LED on and off at regular intervals with Arduino. Teaches the use of digitalWrite and delay functions.
Project that creates a flip-flop effect by sequentially turning on and off two LEDs. Teaches how to control multiple output pins.
Project that simulates a real traffic light with red, yellow and green LEDs. Teaches timing and sequential control logic.
Project that creates a police strobe light effect by flashing two LEDs at fast intervals. Teaches for loop and timing control.
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.
A toggle project that changes the state of the LED (on/off) with each button press. Teaches state variable and debounce logic.
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.
LDR based night light project that automatically turns on the LED when the environment gets dark. Teaches automatic control logic with analog threshold comparison.
Wireless control project that turns LEDs on and off with commands sent from the phone with HC-06 Bluetooth module. Teaches Bluetooth data exchange over serial communication.
Basic usage project that sequentially turns on and off the red, green and blue colors of the RGB LED. Teaches common cathode RGB LED control.
A project that creates a soft rainbow effect by gradually transitioning the colors of an RGB LED with analogWrite. Teaches the logic of color mixing and transition animation with PWM.
