Control LEDs And Buzzer With Potentiometer

Arduino is often used with input and output peripherals. Common output components used with Arduino in mini-projects are LED and Buzzer. Similarly, a potentiometer is a commonly used input device for analog input to Arduino.

In this video, you will learn to make an exciting mini-project where you can control the number of LED's turned ON and the frequency of a Buzzer by a knob(Potentiometer).

Introduction

Arduino is often used with input and output peripherals. Common output components used with Arduino in mini-projects are LED and Buzzer. Similarly, a potentiometer is a commonly used input device for analog input to Arduino. In this article, we will dive into understanding these components and making exciting mini projects using these.

Using Input of Potentiometer to control LED/Buzzer Output

Getting Some Errors? Try these debugging Methods:

1- Display potentiometer input on the serial monitor

2- Check LED if they are working and not fused

3- Make sure resistors attached don’t have very high resistance

EndNote
