Help Any one who Know how to make A mouse Clicke on its own? hmmm>> ^^ Answered

if you could generate negative pulses (is that called monostable? i need to read up on 555 timer modes) from the 555, and apply them to the gate of a jfet, you could easily create the desired pulse switch.

I'm pretty sure it's astable, which means cunstable state (flips back and forth) monostable is just a timed thing, like when I press a button something goes on for 10 seconds then turns off. jfet, bipolar, it doesn't really matter in this situation. Depending on the mouse, and it just needs a logic 1, then you could hook the 555 up directly without a transistor!

youre right. monostable is shot clock mode. and negative pulses to an fet would be the best option. fets can switch faster than bipolar, and are more efficient.

My pointer jumps from one end of the screen to the other sometimes, but never a stray click on its own. But my hand sometimes gets a little heavy on a left click and I end up right clicking also.....makes for some interesting "things" to back out of LOL

Interestingly, mine only does it when I am NOT at the computer. I can hear it clicking, but it never selects anything...

I have taken my hand off the mouse, only to watch the pointer creep up the screen to the far corner already. It is an optical mouse and so that happens sometimes :-) Sounds like you either have a shorted mouse or a ghost cat swatting at the mouse LOL

Lol. I was about to say you need to clean off your trackball (I know, ancient..) before I got to the part about it being an optical mouse.

. Google it

Will either of those do it automatically, to mess with people's minds?

Things were so much easier to emulate just a few years ago...*sigh* EDLIN and a bit of assembly code....now you have to fool with the API for a real click
