As the title says I'm trying to figure out what is needed to activate the power on, on the motherboard's header.
I have read that essentially the switch is a "momentary" switch which I assume just connects for an instant to allow power to boot up. Would more power cause damage or is it just not necessary? Will holding the button down not matter either?
So essentially I am looking to connect some accessories to a microprocessor, and wanted to know if I used something like a touch sensor, or a button on the Arduino, if I could power on my computer?
I found this image and it lead me here, but it talks a bout a lot of things that I'm not sure of like "TTL" it mentions "TTL LOW" which I believe LOW means off? and HIGH is on?
So essentially I'm just curious about the PS_ON since I cannot find much information about it, and I'm interested in how the computer turns on, and how I could do it myself in all sorts of interesting ways that are different from the traditional "pressing a button" to turn on :).
Thank you all for any help/advice. I'm new to electronics, but I know how to write software, so I'm excited to combine the two together!
EDIT: JUST TO BE CLEAR
I am looking to just emulate a button press, i.e., instead of pressing a button, I can click a switch, or something. I want the mb/computer to do what it normally does, but I just want to turn on my computer with things other than the power on button. It seems the easier method is to do exactly what the button does, send the info through the green PS_ON or whatever wire to the motherboard header, and then the mb do it's thing.
