hi All,
just to say I solved this issue. Spent hors changing the delay in both Arduino and Processing and also the Baud rate. I found the right combination that works. I can post it here if anyone would like to se the solution.

best,

Frank

Hi,
ok will have a look at that, but do you think that might be the issue if the code is ok?

Thanks,

F

Hi Robillaart, thanks wasn't quite sure how to do that.  F

Code:

int ledPin = 13;                // choose the pin for the LED
int inputPin = 2;               // choose the input pin (for PIR sensor)
int pirState = LOW;             // we start, assuming no motion detected
int val = 0;   // variable for reading the pin status
float startms = millis();
 
void setup() {
  pinMode(ledPin, OUTPUT);      // declare LED as output
  pinMode(inputPin, INPUT);     // declare sensor as input
 
  Serial.begin(9600);
  digitalWrite(ledPin, 0);
}

void loopTEST(){
float currentms = millis() - startms;

if (currentms > 500){

}
 
void loop(){

Hi Robtillaart,
I've tested all the UNOs with the blink sketch all work as they should.
Hesr is my Arduino code and I have included my Processing code as the sketch outputs a sound in Processing. All of this works perfectly with the ATMEGA 328

Many thanks for your attention.  Frank

Hi All,
I have just purchased 3 new Uno boards which it says are the upgrades to the ATMEGA 328. I have been using an ATMEGA 328 along with a PIR motion detector and it works perfectly, I have 4 of these PIRS and tested all with the ATMEGA 328 and they work fine. Problem comes when I try to run the PIR with UNO, the sensors become extremely unstable and of no use for my task. Of course I have checked serial ports and boards etc, the wiring and code are both exactly the same for the ATMEGA 328 and UNO. I should make it clear that I'm running one sensor with one Arduino at a time.
Anyone else experienced similar problems - I'd be so happy for a solution.

Many thanks,

Frank

Sure I understand your point, thanks. Do you have any advice on which sensor is best to use and how to set it up? I have never tried to do anything like this before but have seen similar type installations in galleries. i am still a newbie to both Arduino and Processing.

TIA,

Frank

Hi I have already considered this and it doesn't matter if one or all three sound sources are playing at the same time, any other thoughts appreciated.

TIA,

Frank

Hi All,
I'm about to start a new project and would like a quick ok or other wise on the feasibility of my idea.
I want to use Processing and Minim with some pre recorded sound - straightforward I know but I also want to use Arduino (pressure sensitive pads, sonar or IR sensors) not yet decided which is best for the purpose.
The idea is that as the spectator walks past a wall mounted object the sound is generated, if they move on the sound stops. There will be three of these in a row approx 1m apart and I want to have the first one go off before the second one comes on and so on....
Has any one any experience of this and if so I would appreciate your comments code tips and any pitfalls.
The second part will involve the participant interacting with objects in a room using the same technology.

Any thoughts, hints etc will be much appreciated.

TIA,

Frank

Hi all,
I have this code that uses a pushbutton to start a chase and I want to alter the end from all the LEDS going out at once to going off one at a time in a random manner. Could someone please help me with the code or tell me what I need to write in order to make this happen.

// A chase controlled by a button

int Button=2; //button assigned to pin 2
int timer = 100; // The higher the number, the slower the timing.
int ledPins[] = {
3,4,5,6,7,8,9,10 }; // an array of pin numbers to which LEDs are attached
int pinCount = 8; // the number of pins (i.e. the length of the array)

void setup()
{
  Serial.begin(9600);
pinMode(Button, INPUT);
int thisPin;
// the array elements are numbered from 0 to (pinCount - 1).
// use a for loop to initialize each pin as an output:
for (int thisPin = 0; thisPin < pinCount; thisPin++)
 {
pinMode(ledPins[thisPin], OUTPUT);
}
}
//turn LEDS on
void loop() {
while (digitalRead(Button)==HIGH);
{
//delay (10);
  Serial.println("LOW");

}

while (digitalRead(Button)==LOW)
{
  Serial.println("HIGH");
for (int thisPin = 0; thisPin < pinCount; thisPin++)
{
digitalWrite(ledPins[thisPin], HIGH);
delay(timer);
digitalWrite(ledPins[thisPin], LOW);
}

for (int thisPin = pinCount - 1; thisPin >= 0; thisPin--)
{
digitalWrite(ledPins[thisPin], HIGH);
delay(timer);
digitalWrite(ledPins[thisPin], LOW);
}
}
}

I thought it might be something like this but can't seem to piece it together to get it to work.

// switch them randomly on and off
int someNumber = 22;
for (int i = 0; i < someNumber; i++)
{
 int thisPin = random(3,10);
 if (random(1) == 1){ // random(1) returns 0 or 1, I hope
  digitalWrite(ledPins[thisPin], HIGH);
 }
 else
 {
  digitalWrite(ledPins[thisPin], LOW);
 }
}
// Finally, switch them all off
for (int thisPin = 0; thisPin < pinCount; thisPin++)
 {
 digitalWrite(ledPins[thisPin], LOW);
}


Any help much appreciated.

Hi, I am so new to this that I don't really understand the answer do you mean I write "turn array on" or something and how do I get it to turn off when the button is "low" is it simply the reverse of this or do I need Arduino syntax (if so iy is precisely this I need help with.

Many thanks,

Frank

Hi Folks,
I would appreciate some help with this problem. I keep getting the message "expected primary-expression before } token"
 I have tried to combine two codes - one which creates an array to make a chase effect with leds and one which uses a button to control an led however i cannot make the button start and end the chase. What am I doing wrong?
I should also say that each code works perfectly before I combine them

Any help most welcome.

Many thanks,

Frank

Hi folks,
got it solved yesterday and just for general info I used this one

and it works fine on both my imac and macbook.

Cheers,

Frank

Hi Folks,
thanks for all the help andI'm making headway at last. I have another question though. I am trying to use Arduino with Processing and the Arduino site list two types of board see below

Processing Library: processing-arduino-0017.zip (Updated 22 Sept. 2009)
Processing library for arduinoMega: processing-arduinomega.zip (Updated 12 Apr. 2010)
however I have the Uno which is not mentioned here. Any suggestions?

many thanks,

Frank
