Hi, I just signed up on here.. I hope this place will be a interesting place to get me going in the world of electronics. I've always messed around with electronics kits from radioshack as a kid but now I'm finding myself wanting to do stuff that requires more.
Basically I am trying to build a simple light using 3.3v LED's that you when you press a button, it turns it on, you press it again, it turns it off. The button has to be a tactile switch because of the small form factor of the device's shell that I'm modding.
It's a mod of an iPod accessory because you know those dock connectors aren't exactly available at Radio Shack![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
The device in question already has a tact switch on board, and it may even have a T flipflop too, the thing is I dunno what it looks like and i can't find any pics of t flipflops.. All I know is it's a skinny long chip with only 4 pins, which seems to match every diagram of a t flip-flop i've seen on the net.
I have a diagram of what I currently have that works here: http://www.aarlabs.com/cdiag.gif.
...using a 10ohm resistor and the LED.
I've been told the best way to achieve what I want is to use a T flip-flop and a pull-high resistor to get it working but I have NO idea how to wire a t flip-flop.. I'm just confused at every tutorial I see online because of there being two outputs and two inputs.
I have a picture of the actual device's board with the pic of what I am suspecting might be a T flip flop here:

That's the device. I have 3 of these things too so it's no problem removing components to see where things go. I already ripped a chip off the back of that one![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Any help would be greatly appreciated.. and I apologize for the crude schematic.
