LED Fun

We used an Arduino board to make 8 LED's flash in patterns. The current code splits them into 2 groups that blink in a line back and forth.

Step 1: Parts

8 LED's

8 520 ohm resistors

10 wires

Arduino Uno

Breadboard

Step 2: Schematic

Each LED receives power from a digital pin at 5V. It then connects to a 520 ohm resistor in series, which leads to ground. The wiring between the pins to the LED's can be changed to make them light up in different patterns.

Step 3: Arduino Code

Upload this to an Arduino IDE and flash it to the Arduino Uno to run the code.
