I got a sound sensor on Ebay some days ago, and decided to give it a try!
Really simple, just made a code to light up the led when the volume was higher than the ambient sound.
Just for fun! 😉
As many people have asked, here goes the code:
Remember that there are many other ways of doing this, for example using the PWM function along with analogRead() and map().
This is a simple and quick code I made for teach variables with arduino programming,
where we enter the variable numbers a, b, c in
and we get the answer using the Serial Monitor..
I won’t get in details about this code, it’s quite straightforward. But if you have any question, just ask! 🙂

Long ago, I wrote How I Made my HTPC at my place. Time passes and things change. End of year has arrived, Christmas and everything, so I decided to upgrade my system to a more efficient and cheaper one. The new choices were using a NAS (Network Attached Storage) allowing all files can be accessed from any machine connected to the network, in this case I am using Lacie Network Space 2 2TB storage. A Gigabit router TP-LINK , so far I’m very happy with this router, although. A media player WD-PLUS Live that has an embedded Linux and play videos in various formats, even FullHD , and access online content like YouTube and some radios.
I made some modifications in one of my projects, my moodlamp, where I mounted it in a CTRL huge key.
I’m planning on releasing all the project as Open Hardware/Source, but due my lack time, it’s not on my website yet!
Would you like to take a look at this project?
Hey, I got so exited about the DotKlok that I decided to build my own! As it’s quite difficult to buy one from here (I live in Florianópolis – Brazil), and to pay U$150 for the Kit wouldn’t work for me… So I want to build a good looking clock for my room, which I only have my computer and mobile as clock.
First of all, I needed to buy the 24×16 Led Display from Sure Electronics, which I found for a good price at eBay (little cheaper then buying from the Website).
This is amazing, perfect for those times when your have to create another board just to hold the atmega µC. I am looking forward to use this tiny board in some project in a near future. Congrats to Varesano for the project.
