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 slightly expensive and sadly we do not h ...

Arduino Phone

Combining Arduino and other shield modules, we make a mobile phone named Arduino Phone. Meanwhile, we printed a shell for it with a 3D printer. Though not as fine as you think, even a little bit clunky, it is still very cool: that is the point--this is a cell phone made by ourselves. Here is a detailed explanation about the steps of making an Arduino Phone, including the hardware connection and software imp ...

DIY Low Cost Arduino Mobile Development Platform

I have wanted to build my own robot for awhile now. But after many tried and failed attempts, I was losing hope that may ever happen. I discovered that there wasn't a small, robust, super easy to add-on to, robot that was within my budget to get. After hours of research and many robot kits later, i decided to build one from scratch. This includes building the base and electronics myself. I was always a fan ...

Control an iPod with the Arduino

This tutorial will describe a way of controlling an iPod remote, and thus, an easy way of getting some music and sound out of your Arduino project. The remote we used was an unofficial remote I found on the worldwide auction site for around 10 USD, an opto-isolator can be found in your local electronics store. We used a TIL116 opto-isolator between the Arduino and the remote to safely send signals in betwee ...
