Nice project. Your track selection was superior as well. Congrats on getting on “hackaday”.

That’s pretty neat use of a LED matrix. I might see about doing something like that myself. I currently have a 8×8 bicolor LED matrix hooked up to an AVR, so far I’ve written a simple pong game.

Wow! I must make one!

I have been looking for a “light organ kit” for a while. This is it for sure.

nice work.

Let me know if you ever do a PCB layout for the whole thing.

cheers,

Is the Arduino and integral part of the project or was it just used to test it out? I’d like to get started in microcontrollers and I’m wondering whether it’s better to order an arduino or a programmer and some chips to tinker with.

By: Alex

Alex — Fri, 14 Dec 2007 00:38:06 +0000

Hi Seb,
I used the Arduino for testing only. Nevertheless, the complete Tengu could be build with the Arduino.
If you are trying to get started with microcontrollers, I would recommend to use the Arduino, because it’s really easy to get things going. No programmer, no soldering, only a breadboard to assemble your first cicuits.
Cheers,
Alex

Seb — Fri, 14 Dec 2007 17:30:23 +0000

Thanks for the reply. I think I will order an Arduino. Am I correct in assuming that if I use the Arduino as a testing ground for a project, that once I have things working the way I want, I can use the code on a standalone chip, in its own circuit? Basically, the Arduino is so that i don’t have to build a voltage regulator or connections or whatever else is needed for a microcontroller to function in a circuit, everytime I want to tryout an idea. Is that an accurate assesment?

By: Alex

Alex — Sat, 15 Dec 2007 08:12:41 +0000

Seb,
the Arduino uses a C as a programming language with some libraries, based on Wiring. If you want to use another micro for your final project, you may have to adapt your code.
Cheers,
Alex

Alex,
Thanks a lot for your responses, you’ve been very helpful.

This is awesome stuff. I am thinking about getting an Arduino for christmas and this is the first project I want to build. What needs to be adapted from your design for this project to work on the arduino? I have never done any “electronics” stuff before and wanted to know if you could make a more detailed writeup of your procedure. im just wondering, but yeah this project is super awesome.

By: Alex

Alex — Fri, 21 Dec 2007 07:44:48 +0000

Hi David,

if you are absolutely new to electronics, I would recommend to start with an Arduino and a breadboard to build the first simple things. Have a look at Boarduino: http://www.ladyada.net/make/boarduino/
After that, take a look at the schematic above. Everything right side of the ATmega is needed for the Arduino version. Additionally the code has to be adapted. Reading the sound sensor is straight forward. Programming the LED display may be a bit harder.
I am not sure, if I find time to do a Arduino version of this. We’ll se.

Cheers,
Alex

By: David

David — Sat, 22 Dec 2007 14:49:29 +0000

Thanks. What are the advantages of using the Boarduino and the Diecimella Arduino? From what I gather, couldnt you just “jumper” the arduino to a breadboard?

By: Alex

Alex — Sat, 22 Dec 2007 18:04:23 +0000

Hi David,
yes, you could “jumper” the Arduino to the bredboard. But if you did that once or twice, you would love to have an Arduino that sticks to the breadboard.
Cheers,
Alex

David — Mon, 24 Dec 2007 02:28:43 +0000

I’m looking at your sound sensor, and I just want to know what parts are being used in the sound sensor/amp part. I think this would be a great instructable

By: Alex

Alex — Mon, 24 Dec 2007 08:46:58 +0000

Hi David,
if you take a look at the schematic, all parts that are at the top are needed. There is a single wire that connects the amplifier with the microcontroller.
Cheers,
Alex

By: David

David — Mon, 24 Dec 2007 18:10:59 +0000

i did look at the schematic earlier, but I was confused because in the schematic you show a 220u capacitor and a speaker. Both not listed on the parts, and the only question I have now is what is the speaker component?

So far my dive into microelectronics has been good. I’ve been collecting parts, and have been testing out things on the breadboard. Thanks for all teh feedback.

By: Alex

Alex — Mon, 24 Dec 2007 22:50:51 +0000

David,
the capacitor and the speaker are used for a first test of the amplifier. They are not need for the final circuit.
Cheers,
Alex

Hey Alex, this is a cool project. Thanks for sharing! Sorry for the off-topic, but what wordpress plugin do you use to display the source code?

By: Alex

Alex — Sun, 06 Jan 2008 13:31:28 +0000

Hi Mark,
check out the “?” at the top of each source code section.
Or have a look at: http://code.google.com/p/syntaxhighlighter/

Hi,

Awesome project. Any chance to sent me the already compiled HEX file? I tried to compile it and program it, but the only thing I got is all the leds lighten up dimmly… No face!!

Regards, Thanos

By: Thanos

Thanos — Wed, 16 Jan 2008 15:30:05 +0000

Oh, and something else, I used a ATMega88 as I could not find ATmega48 here in Greece easily… Do you think that makes a difference?

Regards, Thanos

By: Alex

Alex — Wed, 16 Jan 2008 21:18:19 +0000

Hi Thanos,
I zipped it again and put the hex file into it. Please try it.
Have you tried it on a breadboard? That will be easier to track down bugs in that setup. Try to activate a single face and see if that will light up.

The ATmega88 is pin compatible with the ATmega48. But I am not sure if it will work.
Cheers,
Alex

David — Fri, 18 Jan 2008 13:46:08 +0000

Hey:

I put the amp+mic portion of the circuit together, and hooked it up to my arduino. However, all I get is an led that stays on.

David

By: Alex

Alex — Fri, 18 Jan 2008 18:23:31 +0000

Hi David,

please check if the mic is connected the right way. It has a polarity so you might want to try it the other way round.
Next thing would be to hook up a multimeter at the output pin of the amplifier and see if it changes its value when you shout or touch the mic. Also try to adjust the potentiometers for amplification and volume.
I used a small speaker to “debug” the circuit. For that you will need the 220u capacitor.
HTH.

Alex

Hello Alex, using your experiment as a base, I have developed my own PCB Tengu using a PIC microcontroller.
This video is a brief presentation of PIC-Tengu (http://www.youtube.com/watch?v=MnFP4FNVE-I). It is in spanish but subtitled in english.
Thank you very much for your inspiration; I have enjoyed very much developing ti.

jfmateos2,
man, this one is fantastic. Really good work, much nicer than mine one. Thanks for stopping by.

Alex

Nice project. I want to make this on a uC board that I already have. It has an LCD screen, a microcontroller and a built in microphone. Is there anything I would need to modify or add to get this to work?

By: Alex

Alex — Fri, 11 Apr 2008 14:07:28 +0000

Hi Shevy,
that should be sufficient to get everything to work. Be sure to get a signal out of the microphone, that is strong enough to measure it with the microcontroller.
Cheers,
Alex
