[http://arduino.cc/en/Main/ArduinoBoardDuemilanove Arduino] is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software.

Here is a simple example of how to use Arduino with Elphel cameras. I connected a PIR (Passive Intrared motion sensor) and a button to my Arduino. Motion detection will trigger recording on CF for a minute and the button will store a full resolution snapshot on CF.

As motion detection or button pressure is detected on Arduino it send a _shell command_ to the camera over usb-serial connection. So it is easy to automate everything the camera can do.

On the camera I only enabled FTDI driver in the kernel and run microcom to send output to the shell:
microcom -s 9600 /dev/ttyUSB0 | sh

Here is the source code:
//the time we give the sensor to calibrate (10-60 secs according to the datasheet)
int calibrationTime = 10;
//the time when the sensor outputs a low impulse
long unsigned int lowIn;
//the amount of milliseconds the sensor has to be low
//before we assume all motion has stopped
long unsigned int pause = 60000;
boolean lockLow = true;
boolean takeLowTime;
int pirPin = 3; //the digital pin connected to the PIR sensor's output
int ledPin = 13;
int inPin = 2; // choose the input pin (for a pushbutton)
int val = 0; // variable for reading the pin status
bool pushed = false;
//
void setup(){
Serial.begin(9600);
pinMode(pirPin, INPUT);
pinMode(inPin, INPUT); // declare pushbutton as input
pinMode(ledPin, OUTPUT);
digitalWrite(pirPin, LOW);
delay(50);
//give the sensor some time to calibrate
Serial.print("#calibrating sensor ");
for(int i = 0; i < calibrationTime; i++){
Serial.print(".");
delay(1000);
}
Serial.println("# done");
Serial.println("#SENSOR ACTIVE");
delay(50);
}
//
void loop(){
if(digitalRead(pirPin) == HIGH){
digitalWrite(ledPin, HIGH); //the led visualizes the sensors output pin state
if(lockLow){
//makes sure we wait for a transition to LOW before any further output is made:
lockLow = false;
Serial.println("echo 'status; start; status=/var/tmp/camogm.status' > /var/state/camogm_cmd");
delay(50);
}
takeLowTime = true;
}
if(digitalRead(pirPin) == LOW){
digitalWrite(ledPin, LOW); //the led visualizes the sensors output pin state
if(takeLowTime){
lowIn = millis(); //save the time of the transition from high to LOW
takeLowTime = false; //make sure this is only done at the start of a LOW phase
}
//if the sensor is low for more than the given pause,
//we assume that no more motion is going to happen
if(!lockLow && millis() - lowIn > pause){
//makes sure this block of code is only executed again after
//a new motion sequence has been detected
lockLow = true;
Serial.println("echo 'status; stop; status=/var/tmp/camogm.status' > /var/state/camogm_cmd"); //output
delay(50);
}
}
// button handler
val = digitalRead(inPin); // read input value
if (val == HIGH) { // check if the input is HIGH (button released)
if(pushed) {
pushed = false;
}
} else {
if(!pushed) {
pushed = true;
Serial.println("wget http://127.0.0.1/snapfull.php -O /var/hdd/snapfull`date +%s`.jpg");
}
}
}

In this example I suppose that the camera is configured to record with camogm to the CompactFlash in 1280x720 resolution.
