Story

Hello Friends in this tutorial I am going to show you how to make 3 Led Effects using Arduino Uno. 3 Led Effects means creating patterns with LED's. This is an Arduino beginner friendly project. So let's get started

Components Required

Arduino Uno X 1

LED's (I personally prefer same color LED's) X 3

1k Resistor (1 - For Common ground connection / 3- For each led 5v connection) X 3/1

Jumper Wires (Female - Male) X 4

Breadboard X 1

Connection :-

Connect all your LED's to the breadboard. I'm connection it in a (+ve -ve, +, ve -ve, +ve -ve) manner for easy understanding.

Connect First led 5v(Anode/Positive) to digitalpin5. Second led to digitalpin6. Third led to digitalpin7.

Connect all Gnd(Cathode/Negative) pins of your LED's. Then connect it to Arduino Uno's Gnd pin with a 1k resistor.

Now all connections are complete.
