I would like to know if it is possible to operate an actual push button with some sort of Arduino switching.
I have a photo frame which is operated with three push-buttons. Already stript the casing off and the buttons are mounted on two leads. When i put a metal strip from one lead to the other, it makes contact and operates the frame-button.
What i want to do is solder two wires to the leads and let arduino make the contact to emulate the push.
just starting with Arduino, so have a little patience with my ignorance :)
I tought just make a connection with two leads to the arduino, program a on/off like switching a LED on/off. Put a resistor on the positive lead to reduce the 5v to 0v. This would make the physical path, to operate that switch without actual power.
Am i on the right track, or do you say "No Noob, completly wrong...."
Any help is greatly appreciated
