I gotta try this :3
B-dui in creation.

big93

can you find the parts necessery to make this work in radioshack? becuase i'd love to be able to have a tv screen as a display...

Alastair.Parker

Yeah, just a couple of resistors (the values don't have to be exact) and an RCA jack.

Make sure you have the 75() resistor correct or else you may not see anything on your tv! also check the voltages with a multi meter can save your tv from more current then nesserary or worse! Have fun

Hi everybody,

here a code derivated of arduino pong,

enjoy it,

Hello, I am working on an interface that converts midi signals into visuals. I based this on the arduino pong code. Now I am on the end of my ideas. the 2 parts: Midi Input Signal and Arduino pong works seperately perfekt but its so hard for me to connect them. I hope there is someone out who can help me
I did the midi input shown here: it works

Code: [Select]

#include <MIDI.h>
/*
 Basic I/O MIDI tutorial
 by Franky
 28/07/2009
*/

#define LED 13               // LED pin on Arduino board

void setup() {
 pinMode(LED, OUTPUT);
 MIDI.begin(4);                  // Launch MIDI with default options
                       // input channel is set to 4
}

void loop() {
 if (MIDI.read()) {
   digitalWrite(LED,HIGH);     // Blink the LED
   MIDI.sendNoteOn(42,127,1);  // Send a Note (pitch 42, velo 127 on channel 1)
   delay(1000);            // Wait for a second
   MIDI.sendNoteOff(42,0,1);   // Stop the note
   digitalWrite(LED,LOW);          
 }
}


here is now my code that I build :-(
The midi request doesn 't work. My goal is to show different pictures with different midi nots from my drumcomputer.
If Midi Note 1 and Velocity 1 arrives show Picture 1
If Midi Note 1 and Velocity 1 arrives show Picture 12
its important that the programm asks the whole time if there is a new Midi note.
....
here is the code mixed with the arduino pong code. Now I can just see 2 does because the programm steps in the following else if part

else if(midi < 40 & midi < 30)
 {
   digitalWrite(ledPin, HIGH);
   grayPixel(5,10);
   setPixel(10, 20);
   //clearScreen();
 }

this is the code

i will try this for sure

SoranneFr

Hi,
I'm working with an Arduino Mega which has a 16mHz Quartz, do you think it will work well, or do I have to change the code?
(Sorry for my bad English, I'm French  ;D)

Interesting Project...

Thank you ;D

Sorry for kicking the project, but it is worth it.

I have made this project and I have used (TIP!) two variable resistors for pin 8 (synch) and instead of the 75 Ohm. That makes it easier to reach those values.

The game works in part:
- startup is crystal (clear)
- playing is very bad, the problem is with the updates (they should fall between scanlines but they don't making the screen flicker)
- between two rounds (after a 'ball' is missed) the screen is nice again.

putting UPDATE_INTERVAL to 100 helps (although it flickers after that), but the games is unplayable then...

I use CLI so that should be ok. I have a duemilanove with an 328 uC.

[UPDATE:]
It was caused by delayMicroseconds(10); around line 558. removing that made my game work at least ;).

Martin Gerken

Is the 75 Ohm resistor really needed? The linked page that explains signal generation put this resistor INSIDE the TV. The Other arduino TV-library did not recommend this resistor either!

condemned

I don't think it's neccesary for most TVs. The 75ohm resistor is implied as being in the TV.
See this thread at AVRFreaks for probably more information than you wanted (note that the resistor values are slightly different because of the inline diodes).
