How to Control Multiple LEDs with Arduino | One Pin vs Multiple Pins

Learn how to control multiple LEDs with Arduino using one pin or multiple pins. In this beginner-friendly tutorial, we’ll look at the maximum current an Arduino pin can safely handle, how to apply Ohm's Law, and how to program a sequential LED chase effect. Hi Makers! Welcome back to Lesson 5 of our Electronics & Arduino for Beginners series! 🚀 In this step-by-step Arduino tutorial, we’ll cover: How to connect and control three LEDs using a single digital pin Understanding the Arduino current limits per pin and why it matters for safety Using Ohm's Law to calculate the correct resistor values Connecting multiple LEDs to independent digital pins for separate control Writing code to create a sequential LED chase effect By the end of this video, you’ll know exactly how to safely power multiple LEDs, calculate resistor values, and program your own custom LED sequences.
