ps2 mouse with click wheel -- lost in uncharted techspace

I must tell you all, I haven't the money to buy a Multimeter, at the moment, and don't want anybody offering me one (my parents want me to do things on my own, on account of my High-Functioning Autism).

Well here is the question: I have an old ps2 mouse with a click wheel. Since I don't have a multimeter, I am wondering if any one could direct me to a thread or website stating a person's findings on which wires do what.

I have looked on Google and on this forum and haven't found what I am looking for.

Thanks,

Drac?

all ps2 mice have the same pinout

and they communicate to the computer using a synchronous serial system (clock and data) what those packets of info contain lets the computer know how many buttons, if there is a wheel and in what mode the mouse is

Well, I cut the connector off. :frowning:

Any way to tell which wire is which?

Assuming red is voltage, black is ground. That leaves the green, sky blue, a bare steel wire, and a type of foil. I believe all the wires are stranded.

I am guessing I should not have cut it.

its hard to tell, when they make those cables the colors end up everywhere, heck I even had one keyboard with the circuit inside mismarked

the only one that is 100% is the bare wire, that goes to the shell of the connector

if you dont have a multimeter you can rig up a 9 volt battery, resistor and a LED

You're in luck:

http://www.harborfreight.com/ky/lexington.html

Go there - buy this:

http://www.harborfreight.com/7-function-digital-multimeter-92020.html

Use the 20% off coupon, and you can get it for $3.99! Heck, most of the time it is on "sale" for $2.99.

Hell - I have a coupon to get one free (good until 9/10/2013)! Message me your postal address, and I will send you the coupon.

You have NO EXCUSE NOW. If you don't want the coupon, that's fine. But I do wonder why you are able to afford an Arduino, but not less than $5.00 for a multi-meter? Heck, go without lunch for a while (ok - maybe school is out for summer right now) and save your lunch money (I did that all the time to buy Nintendo cartridges from other kids - those were the days!)...

My parents bought me the Arduino for graduating high school this past May.

I am going to take an electronics class this fall at college and I want a good multimeter that will last a long time. Also, I have only 8 cents in the bank and no job.

Let me tell you something - there isn't much difference between these low-cost meters, and slightly higher-cost meters (now, if you're talking a Fluke - big difference).

I like the HF meters as "throwaway" meters. For the most part, they work well (for hobby-grade work), you don't worry about breaking them, and if you do blow the meter accidentally (which you can easily do with an expensive meter as well!) - you're not out much money. They are great when you need to measure tons of things in your circuits all at once.

Every time I get one of these "free meter" HF offers, I use it - but I am still offering it to you. I can easily send it to you. The offer is still open.

If not - then I'll just grab another myself. I probably have 20 of them that I've collected over the years. I also have a couple of "good meters" (but I still don't have a Fluke, and probably never will - but I do have a nice Fluke Combiscope - heh). For hobby-level work (and automotive work) - cheap HF meters are all you really need.

agreed, I have a el-cheapo craftsman and a very snotty tektronics, for most applications they are interchangeable

Ok, I see what you are saying.

I will message you my address.

When does the coupon expire?

No I didn't - are you sending me a PM via the Arduino forums? Or some other method?

Ok, I am sending my address to you through Arduino Forum Message Service (ArduForMS).

If you still have the cut off connector, then you can match the wires by colour to the diagram posted earlier in the thread...

The connector is probably long gone.
