Hello. Am trying to make an portable automated water sampler, based on a RTC trigering- triggered by the time besed on my needs. It needs to be triggered by a specific time, because I will put a color to a stream (at different times) and i would like to be able to gather samples of water in predetermined times even thought I will not be present.
I am an complete "idiot" in arduino, so the idea that I have come asross is... mechanical pump, that is triggered (I managed to do that in code), but I need one servo motor, that is turned for a specific angle (or revolutions) in my specified time that will turn a cylinder holding 24 bottles.
Can please someone help me with the code, or changing the code, so that there is servo conection in it that is based on triger time?
sorry for my english I hope that you understend what i would like to do

I don't know what an "accu" is. Can you elaborate?
You do not need a servo, etc. to move a bottle table. You need to design the mechanism that can use a simple DC motor/gears box, to move the table and have a micro switch indicate a stopping point has been reached. Keep it SIMPLE!

with "accu" I meant battery (it is called akumulator in Slovene, si I stupidly used accu as we say in Slovenia).
That is really a good idea. I will start to do simething in that direction..

That is very interesting. I wonder what you call an actual accumulator, such as used in hydraulic systems to even out the pressure. Same for refrigeration systems.

if am not mistaking and we are thinking of the same stuff... we call it expansion tank.
As for the micro switch you mentioned.... thats a great solution, I can easisly put the it in the power line of the dc motor and the motor then stops- but what if I want the rotation of plate to continue in the same direction, but the switch is still on?

This is an Arduino forum. I thought you wanted it to control all this stuff. The micro switch just tells Arduino when to stop the motor.
We also call it an expansion tank as well as an accumulator.
Several years ago some relatives of people in our church went to Slovenia to start a church. Brought many pictures. Beautiful country!
