There are already some NFC jukeboxes. Off the shelf like those “Toni” boxes. For do-it-yourself: lots of instructables. This device should cover as much as possible, which could come into question sometime and somehow. It should have as few weak points as possible, (in which a 3-year-old could put things). Easy to use, easy to […]

This project is for the class ATLS 3300 at CU Boulder. Push buttons can make buzzers sound. Five buttons represented the tone C, D, E, F, G. There are two modes. The switch determines the mode and LEDs can indicate which mode we are in. In mode-1, the game handle can determine which buzzer sound.

In this pandemic it is important to take reasonable measures to reduce spreading viruses. A paper from 2019 found that louder voices spread more viruses (https://www.nature.com/articles/s41598-019-38808-z) [Asadi et al. 2019]. This simple project aims to remind people to not shout unnecessarily. This can be used in classrooms, meeting rooms or any other setting where people

This project was submitted to ‘Creative Electronics’, a Beng Electronics Engineering module at University of Málaga, School of Telecommunications (https://www.uma.es/etsi-de-telecomunicacion/). It’s a modification based on sound level meters that are already marketed for use in classes to measure ambient noise. The project is developed in Arduino. It consists of a LED screen in which emoji

The purpose of this Instructable is to build a portable device that can measure the speed of sound in refrigerant gases and use this data to identify them. The speed of sound in an ideal gas is related to two characteristics of the gaseous substance, its molecular mass (kg/mol) and its adiabatic constant (heat capacity ratio), or

Making a hardware synthesizer is a really fun and rewarding experience. But usually with a lead synth you would want to implement ADSR envelopes, multiple adjustable oscillators, multiple types of filters for each, polyphony et cetera et cetera. Those aren’t conducive to a beginner project, but it definitely isn’t impossible to make something that sounds

In this IoT project, I have shown how to make an IoT-based Home Automation with Arduino IoT Cloud & Alexa using ESP32 to control 4 home appliances with voice commands. If the internet is not available, then you can control the home appliances manually with switches and IR remote. During the article, I have shown

People love listening to music. It is as they say, music reflects our mood. And it is a spectacle to see music become ‘alive’ right before our eyes. Well, that’s what music visualization does. According to Wikipedia, music visualization “generates animated imagery based on a piece of music. The imagery is generated and rendered in

In this tutorial we are going to show you how to make an interactive sound wave print within a picture frame, so you can see and hear your favourite song at the same time! When you touch the print through the glass of the frame, it will play the song shown in the sound wave

Hi, today I’ll explain how to make your own little Weather based Music generator. It’s based on an ESP8266, which is kind of like an Arduino, and it responds to temperature, rain and light intensity. Don’t expect it to make entire songs or chord progressions. It’s more like Generative Music people sometimes make with Modular
