How can you make a buzzer play a melody with your Arduino?

To make a buzzer play a melody with an Arduino, you can use the tone() function to generate specific frequencies that correspond to musical notes. A simple way to do this is by using an array of note frequencies and durations, then iterating through them to play the melody. Wire Connection: Arduino Code: Explanation: This … Read more

How can you make an LED slowly get brighter and then dimmer again?

To make an LED slowly get brighter and then dimmer again, you’ll need to control the LED’s brightness using Pulse Width Modulation (PWM), which is supported by several Arduino pins. You can achieve this by gradually changing the duty cycle of the PWM signal. Components Needed: Circuit Setup: This limits the current flowing through the … Read more
