Some wires

This project involves writing an Arduino program to create a fading effect for an LED using a loop. The goal is to gradually increase and decrease the LED's brightness, producing a smooth transition from dim to bright and back to dim. This is achieved by using Pulse Width Modulation (PWM) on one of the Arduino's PWM-capable pins. The program uses a loop to incrementally adjust the duty cycle of the PWM signal, creating the fading effect. This project is perfect for beginners learning about PWM, loops, and basic LED control with Arduino, offering a foundational understanding of how to manipulate LED brightness in a controlled manner.
