1  Using Arduino / Interfacing w/ Software on the Computer / Re: Using a arduino board for a Serial interface? on: June 07, 2012, 04:46:54 am
But the chip used on the board creates a serial port on the computer. What I am asking is can I use the usb serial chip to do it.
2  Using Arduino / Interfacing w/ Software on the Computer / Using a arduino board for a Serial interface? on: June 07, 2012, 04:40:19 am
I am asking if it is possible to use a old arduino board (which has no arduino chip from where that died) as just a serial interface for my raspberry Pi

Does anyone know if this is possible and what application I can use to communicate with the serial port.

Thanks it works now smiley-grin

And yes an resistor is now on it :3

Edit: In the end to be super safe I used an H bridge chip and an separate power source for the speakers. Its working great smiley-grin

Its not like I was going to leave it in there. What use is it seeing an LED fade.

I also have tried an small speaker setup how the tone sketch shows using pin 3 instead of 8. Still nothing

The tutorial code has an slight variation which also outputs to pins 10 and 12 for LEDS. Nothing come out of these (these two with resistors)

Nope, No resistor it was just to quickly see if there was output.

Theres lots of videos of this project. Theres even an tutorial at http://www.instructables.com/id/Arduino-Chiptunes/, An quick youtube search shows lots aswell.

I think it might be something to do with it being an mega. I remember having to use different pins for the WiiChuck lib aswell.

I wired up an jack to one of my monitors (I don't know how many ohms)
I then tried just wiring up an LED to see if there was any output at all.
7  Using Arduino / Audio / Chiptune Project don't work on Mega? on: April 29, 2012, 07:23:23 am
Well after coming across an arduino port of an chiptune I like I then uploaded it to my Mega and plugged in speakers wired up to PWM 3 and ground.

Nothing plays at all :C

The original post for this was @ http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1265488118 and all tutorials / posts online are using the Uno.

Does anyone know how to get this to work on the Mega (1280)?

Thanks - Ryan

Changed to my arduino number and this command worked smiley

Now i just got to make it a looping SH Script smiley

Hi
i basically want to know how i can make Ubuntu output to the serial port every min the CPU Load

You can run this command to find the load

Quote
uptime | sed -e "s/.*load average: \(.*\...\), \(.*\...\), \(.*\...\)/\1/" -e "s/ //g"

How would i do this?

I have decided to use LEDs instead
I am going to try and program this in VBB First then i will make the hardware after.
11  Using Arduino / Project Guidance / Re: Stacker Project. on: May 31, 2011, 03:08:38 am
Would it be better to power the lights another way then. ( I only have 10-20 pounds to spend on this project.
12  Using Arduino / Project Guidance / Re: Stacker Project. on: May 31, 2011, 02:58:50 am
That I don't know about, Until I get home from my holday ( about 3-4 hours now) I won't beable to test. My lights out.  They were from a chrismas tree and I was Going too see if I can make my own matrix out of it. They also only require a low voltage and were designed to be turned on and off quickly.  If not what other way would I power the lights?

Sure you can code this on Arduino.  The controller in the commercial game machine likely isn't significantly different than Arduino.

By the looks of it , it was just a few chips with 4 buttons on it and a ticket dispenser.


The only tricky part may be the 9x7 array vs 8x8.  You can certainly wire it to 63 lights, but you will have to "tweak" the code to cheat one row to look like a column. Certainly possible, but not exactly straightforward.
This is what i was thinking, The matrix would be identical for the first 8 rows but only use 7 rows wide so then the last row would technically be at the top and turned sideways.

Remember that if you want to do more than one color, you will need multi-color lights and more than one MAX7219 chip.

I have only got just plain lights, as I would be making the stacker myself I would look into buying some overlays or gels.

The hardest part i could think of is programming it to know to make the blocks "Fall" so then it shows it falling down.

I am also thinking to code the button to stop the blocks as a physical button and also listen to the serial port so i could hook a webcam up to it and be able to play it online.

Hello,
At the moment i am looking to start a project to make my own Stacker like seen in arcades ( http://laigames.com/stacker_std_club.html )

 The aim of the game is stack the blocks up to the top, Each level the blocks get slightly faster etc. Luckily i have been able to see inside of this machine and it is designed to make people lose E.G one in every 10 people will win [1:9]. 

How the Machine Works :
The amount of blocks high can very on the machine but the width is always 7 The height i counted was 12 - 15 blocks high,
 When starting you get 3 blocks to stack with, After it stacked up to the one before the minor prize is stacked it goes down to 2 and again after another 3 it goes down to 1. If you stack just one or two blocks on top of the 3 you then only have 3 etc ( More Information Can Be Found Here : http://laigames.com/The%20Stacker%20Family%20Dec%2009.pdf  Pages 12 - 15 . )


My Version :
My version would be 7 blocks wide and 9 blocks high , I am skipping out the half way point as there will be no point in this. 

The Programming : I am hoping to use the MAX7219 chip ( goo.gl/HkYJZ ) which is was used to power 8x8 matrix displays. I have over 64 lights although i would only require  63 ( 9*7) These are light bulbs that require 9 volts ( this is another reason why i think the max 7219 chip would be best. Otherwise all the programming should hopefully be simple to do ( I don’t know i’m still a noob at programming arduino)

The question is would this be possible to code.

Thanks - Ryan Walmsley

I have also made a google drawing here - https://docs.google.com/drawings/d/1daJRsfs6-51O6kj-TUmNYneI7sF43pOYJ5mmnAs_T-E/edit?hl=en_GB

hmm i might just try making Chiptunes as i like the music part aswell.
