This easy Arduino project for beginners can be built on an electronic breadboard and uses only four LEDs and four series resistors to make a moving light display. The Arduino sketch for the project can be modified to change the rate at which the pattern on the LEDs is updated. The patterns to display on the LEDs can also be changed.
Details of this Arduino Project for Beginners
A breadboard is used to connect four LEDs with series resistors to an Arduino which can be an Arduino Uno or other Arduino. Four wire links connect the LEDs to four of the Arduino pins which are set as outputs. A common GND wire from the Arduino is connected to the breadboard which connects the other side of each of the series resistors to GND. This completes the circuit and enables the LEDs to be switched on by the sketch running on the Arduino.
