Simple switch via Pi

Wed Apr 06, 2016 10:16 am

Hey all.
I want to use the output from my pi to act like a basic switch to an external circuit. I have wires rigged up to the pins on my motherboard and previously used a mobile phone to complete the circuit and thus switch the power on (I did this via the mobiles speaker terminals). Is there an easy way to do this? I do not need any power output from the pie, just to connect the two sides.

Apologies if this is a really stupid question but I am incredibly new to this stuff and when I searched, the answers I found were more complicated than I thought they should be.

I am using the Pi to complete a low-current circuit. I asked how to do it in another part of these forums and received very helpful answers. The link is here viewtopic.php?f=37&t=126105&p=926541#p926541

Scroll to the end to see how to do it.

connect a output pin to a diode and use a transistor as a switch for the curcuit
