 Bigger Bigger  Smaller Smaller  Reset Reset

Hi. I have a simple question. I want to control my actuator using arduino in two ways: full extend and full retract.

The materials that I have at the moment are:

-Arduino Uno Rev.3

-Linear Actuator which I got here http://www.olx.ph/index.php/view+classifieds/id/52958330/Linear+Actuator++24+v+225+lbs+12inches?referralKeywords=linear+actuator&event=Search+Ranking,Position,1-3,3

-4 Channel Relay Board which I got here
 http://www.olx.ph/index.php/view+classifieds/id/50206871/4-Channel+Relay+Board+Module?referralKeywords=relay+board&event=Search+Ranking,Position,1-3,3

Can you help me with the arduino code and the wiring connections? And also what other components should I buy if I need any? Thanks!

These two instructables will let you switch the relay on and off from your Android mobile using a custom menu you design.  No coding required.  All the Arduino code is generated for you and the universal Android pfodApp has already been written.  (see www.pfod.com.au)

Also see http://www.instructables.com/id/Home-Automation-How-to-Add-Relays-to-Arduino/
for relay module wiring examples.

BUT...  You probably want some sort of feedback to let you know were the actuator is.  Not clear from your link if there is any built in position sensor on the actuator.

In theory there is no difference between theory and practice, however in practice there are many...

I do not see how (most of) your response helps the OP with his question.
It looks more as a commercial for your website == spam

Can you please explain?

My impression of the question was how to control relays and wire them up.  

Answering his question "wiring connections"
The url to relay module wiring examples is just relay choice and wiring information.

The other url shows how use a free app to generate the Arduino code need to drive the relays from a customisable Android menu.  So it is answering his question on "help with the arduino code"  
The actual code generator is a free app and provides  template Arduino code for doing what he wants even if he does not use pfodApp to drive it.  The resulting code generated is well commented so he can strip out what he does not want.

I believe my app provides an easy way do custom relay control.  So I suggest it as a solution where it seems appropriate.  I am not aware of any other code generator for Arduino that provides a complete solution for custom remote control of relays without having to write any code at all.

My impression of the poster's question was that he would like all the help he can get to get up and running.

Finally my post raises a question that does not seem to have been considered.  That of sensing where the actuator is so you know when to turn the relay off.  I may be that he will do this visually.  But in that case I am not clear why he is using Arduino.

Perhaps we should wait for a reply from the original poster before trying to decide how useful my post was to him.
