hi there
i hope someone can please help me
i have two pieces of code and i need to merge them together and i am a bit stuck.
the first bit of code is arduino2max code which has been changed a little so that it reads values from 6 distance sensors on a wall which are chained together so that it repeatedly reads the values from the sensors in a loop and sends them to the arduino analogue pins
i am trying to incorporate some code for a pir sensor that is connected to a digital pin so that when the pir sensor detects motion it then turns on sound in max msp and if no motion is detected it turns the sound off.
hopefully this will solve a problem that i am having with the distance sensors which sometimes give false readings when no one is present and therefore make unwanted sounds
this is the arduino2max code :
int x = 0; // a place to hold pin values
int ledpin = 13;
void setup()
{
Serial.begin(115200); // 115200 is the default Arduino Bluetooth speed
digitalWrite(13,HIGH); ///startup blink
delay(600);
digitalWrite(13,LOW);
pinMode(13,INPUT);
delay(500);
digitalWrite(12,HIGH); // this part is the code to send the first pin in the
delay(20); // chain high so that the sensors then give continuous reading
digitalWrite(12,LOW); // one after the other
pinMode(12, INPUT);
}
void loop()
{
if (Serial.available() > 0){ // Check serial buffer for characters
if (Serial.read() == 'r') { // If an 'r' is received then read the pins
for (int pin= 0; pin<=5; pin++){ // Read and send analog pins 0-5
x = analogRead(pin);
sendValue (x);
}
for (int pin= 2; pin<=13; pin++){ // Read and send digital pins 2-13
x = digitalRead(pin);
sendValue (x);
}
Serial.println(); // Send a carriage returnt to mark end of pin data.
delay (5); // add a delay to prevent crashing/overloading of the serial port
}
}
}
void sendValue (int x){ // function to send the pin value followed by a "space".
Serial.print(x);
Serial.print(32, BYTE);
}
and this is the pir sensor code, from elsewhere on this site
int ledPin = 13; // led connected to control pin 13
int PIRSensor = 2; // the PIR sensor will be plugged at digital pin 2
int state = 0; // variable to store the value read from the sensor pin
int statePin = LOW; // variable used to store the last LED status, to toggle the light
void setup() {
pinMode(ledPin, OUTPUT); // declare the ledPin as as OUTPUT
pinMode(PIRSensor, INPUT); // declare the PIRSensor as as OUTPUT
Serial.begin(9600); // use the serial port
}
void loop() {
state = digitalRead(PIRSensor); // read the sensor and store it in "state"
if (state != 0)
{
digitalWrite(LED1, HIGH);
Serial.println("Motion Detected!"); // send the string "Motion Detected!" back // to the computer
}
else
digitalWrite(LED1, LOW); // turns light off if motion is not detected
delay(100); // we have to make a delay to avoid overloading the serial port
}
i hope that this is clear and someone can help me out as i am desperately trying to get this sorted out for an impending show
many thanks in advance for any advice
