Wireless Audio Transfer Using LASER Light In this article, we are going to discuss how to transfer audio through laser light. This is a fun little project, and the concept is similar to what we see in fibre optics cable. We will use a laser light to send data from one point to another. To be particular, in this project here, we are going to transfer our voice from one point to another by shining a laser light on a solar panel. This… |

Interfacing MAX4466 Microphone Amplifier Module with Arduino As you may know many of our everyday appliances or devices such as smartphones, home automation systems, smart speakers, headphones and many others have their own built-in microphones to capture the audio data. And if we look at them there are different types of microphones available, such as condenser, ribbon, dynamic and MEMS. Most modern devices like smartphones… |

Measure Sound/Noise Level in dB with Microphone and Arduino Noise pollution has really started to gain importance due to high population density. A normal human ear could hear sound levels from 0dB to 140dB in which sound levels from 120dB to 140dB are considered to be noise. Loudness or sound levels are commonly measured in decibel(dB), we have some instruments which could measure the sound signals in dB but these meters are… |

Arduino Whistle Detector Switch using Sound Sensor As a kid I was fascinated by a toy music car which gets triggered when you clap your hands, and then as I grew up I wondered if we can use the same to toggle lights and fans in our home. It would be cool to just turn on my Fans and lights by just clapping hands instead of walking my lazy self to the switch board. But often times it would malfunction as this circuit will… |

Simple Microphone to Speaker Amplifier Circuit You must have seen someone speaking on the MIC and the amplified voice coming from the speaker, how this is possible? Is there any circuitry between MIC and speaker of we can directly connect Microphone with speaker to get it working? In this circuit, we learn to build a simple Microphone to Speaker system, in which input sound is given to the MIC and we hear the amplified… |

Arduino Based Guitar Tuner Hi guys, during the last few weeks, I’ve been working on reconnecting with my love for the guitar. Playing the box guitar was how I relax few years back before the saxophone took over. Going back to the guitar, after 3 years of rarely strumming a chord, I discovered amongst other things that I no longer knew how each of the string should sound, to put it in my friend’s words… |
