+Lights for optimal plant growth were separated in a 2x 12 hour rhythm. First 12 hours was steady light. Another 12 hours the light only turned on once in every 5 minutes - right in the moment a photo was taken. So the plant got a period of nearly complete darkness to retire from growing.
+Implemented with Arduino, Processing, a radio switch, a radio transmitter and ControlMyNikon.
+Processing Code:
+<quote>
+import processing.serial.*;
+int colour = 0;
+boolean sign = false;
+Serial port;
+void setup(){
+//println(Serial.list());
+String portName = Serial.list()[0];
+port = new Serial(this, portName, 57600);
+}
+void draw()
+{
+  fill(colour);
+  rect(25,25,50,50);
+}
+  /*if (hour() < 12) {
+    port.write('H');
+    delay(3000);
+    port.write('L');
+    delay(297000);
+  }
+  if (hour() >= 12) {
+    port.write('H');
+    delay(1000);
+  }*/
+//CONTROL BY MOUSE
+void mousePressed() {
+colour = 200;
+port.write('H');
+}
+void mouseReleased() {
+colour = 70;
+port.write('L');
+}

+Adruino Code:
+<quote>
+#include <RCSwitch.h>
+int incomingByte;
+//int ledPin = 13;
+RCSwitch mySwitch = RCSwitch();
+void setup()
+{
+  Serial.begin(57600);
+  mySwitch.enableTransmit(10);
+}
+void loop()
+{
+  if (Serial.available() > 0)
+  {
+    incomingByte = Serial.read();
+    if (incomingByte == 'H')
+    {
+      Serial.println("on");
+      //digitalWrite(ledPin, HIGH);
+      mySwitch.switchOn("01110", 2);
+    }
+    if (incomingByte == 'L')
+    {
+      //digitalWrite(ledPin, LOW);
+      Serial.println("off");
+      mySwitch.switchOff("01110", 2);
+    }
+  }
