Hey im trying to make an arduino uno send a 5 volt signal (That i can controle in IDE.) to then controle a function i have set up on a breadboard. Is this possible?
side note: Maybe i can controle with the ground. can not find anything about it.
Thanks in advance.
Your question is not much specific. Please read this link and update the post.

Yes, as long as the 'function' on the breadboard shares a GROUND with the Arduino and doesn't draw more than about 20 mA from the signal line.
