Arduino with Speakers Project #01 a Introduction In this project the speaker will make sound whenever the infra red (IR) sensor connected to the Arduino detects any obstacle. Elements Required  Arduino Speakers Infra Red (IR) Sensors Breadboard Connecting Wires Infra Red (IR) Sensors  IR Sensors work by using a specific light sensor to detect a select light wavelength in the Infra-Red (IR) spectrum. By using an LED which produces light at the same wavelength as what the sensor is looking for, you can look at the intensity of the received light. When an object is close to the sensor, the light from the LED bounces off the object and into the light sensor. This results in a large jump in the intensity, which we already know can be detected using a threshold. IR Sensor Connection With Arduino Connections of IR Sensor The IR Sensor have three pins: Vcc : connect to 5V of Arduino GND: connect to Ground of Arduino O/P : Output connect to I/O pin of Ard

SPEAKERS ARDUINO INTERFACE Arduino Speaker Setup INTRODUCTION  This Arduino project is one of the most simplest Arduino projects which you can build in minutes. The main thing which makes this project super simple is that this project requires only one extra component. If you are new to Arduino, this tutorial will help you get familiar with Arduino and learn the basics of Arduino programming. This musical project has a speaker which plays out a song. If you ever wanted to add some sound to your existing project, you can do it easily with this Arduino speaker tutorial. You can even make a musical car reverse horn and make it play the latest songs always. You can change it easily by uploading a new program. If you still remember how you made ringtones on those old Nokia cell phones, you pretty much have all the knowledge required to make any song with this project. Let’s get started. What are the stuff required to do this? An Arduino A speaker or a piezo buzzer
