 Der Schlitten läuft auf zwei parallel gelegten Edelstahl Stangen welcher über einen GT2 Zahnriemen mit einem Schrittmotor angetrieben wird. Die Steuerung erfolgt auf einem Raspberry Pi auf dem ein Skript mit freier Eingabe der Variablen (Belichtungszeit der Kamera, Schrittzahl bis zum nächsten Foto, Geschwindigkeit und Richtung) läuft.

 Das Python-Skript frägt am Anfang die benötigten Informationen wie oben genannt ab. Danach kommt die Initialisierung, damit der Schlitten an das Ende der Schiene fährt. Es folgt das Abfahren der Positionen bis zum anderen Ende der Schiene. Des weiteren sind Funktionen wie das automatische wegfahren des Schlittens vom Endanschlag und Schalterentprellung mittels Software im Skript integriert.
-  *** Die Entprellung ist für einen sauberen Programmablauf notwendig, da evtl. Funktionen mehrmals aufgerufen werden.**

+RELEASE NOTES
+Please note that this Version doesn't contain an user interface (UI). You have to enter all values manually in the Parameter / Varaible section
+in the head of this program. Feel free to copy this and build your own camslider.
+**Version 1.0**
+    First release of the Arduino Program for Camslider.
+    ***WORKING:***
+    -Initialisation
+    -Move from point to point
+    -Auto Reset after reaching the other end of line
+    ***NOT WORKING / NOT IMPLEMENTED***
+    -RUNTIME (means to set a time which gives the duration of the real time duration of a timelapse for example)
+     --> does not automatically calculate the amount of Move Step and Exposure Time
+    -Cameracontrol
+    -lots of more ideas
