Advanced Microcontrollers & Wired/Wireless Communications assignment by Martin Weiss Hansen

For this assignment I chose the post-it pair: Microphone + noisy environment:

I wanted to do a decibel meter for use with a laptop. A decibel meter measures the sound level of the environment. Measuring the sound level is important because high sound pressure levels are harmful for human ears. The microphone of the laptop registers the sound level, and an LED lights red if the sound is harmful, green otherwise.

Processing and Max/MSP have been used for the prototype. MaxLink is used to send data from Max/MSP to Processing and from Processing to a BlinkM which is connected through a LinkM USB programmer. Examples from MaxLink are used as a basis for the prototype.

The following is a demonstration video (please note: for the video there was no LinkM/BlinkM available, a screen set up by Processing was used instead):

Further iterations of the prototype could include other sensors to detect the state of the environment.
