I've always used off page connectors with the same name, but that was the way i was taught in school. They have always worked fine for me but i have never used ports.
Not sure of the difference. Whatever works i guess, depends on the application.
I have it working, but for some reason when the motor turns on at like 2v all the LED's come on for the ADC. it works fine before the motor comes on then they all come on when the motor turns on? and guesses why?
I have a friend who has the CoolerMaster Centurion 590, I can't really tell you anything about it except hes had no problems with it, and his computer runs at about 982127 degrees :eek:
The 590 has more ventelation it seems. Not much help but :D
Hello!
Welcome to the forum. I am also pretty new here, the guys here are good at what they do and give plenty of help. You learn fast.
I am also doing an electronics engineering technology program, what year are you in? how do you find it?

I actually have the same circuit built, but i didn't check the base of the transistor, so i'm not sure what is on mine.
Do you have any output on the collector?
Thanks, ill look into that. I'm thinking about scraping the IR idea all together. Just seems like the IR like wont reflect like i want it to.
Did you ever see anyone build any ultrasonic/sonar sensors?
All i really want it 0v output when your 4feet away and 5vdc when you 4 inches away type...
Hello all,
I am building a distance sensor..I have the ucontroller portion done. I was going to use IR to reflect a beam and get a proportional analog voltage to estimate distance but...it has no range:mad:
Any ideas/methods?

Update for those of you who care:
I think i got it working now...i re-programmed the chip using HS instead of XT and turned the rigth fuses on and off..well see how long it last this time.
Ok, it was fully working well, then i reconnected the circuit and now...it onlt works when i take the crystal out and put it backl ...it reads the vvalue and displays it.
it only changes when i take the crystal out and put it back it..it will not do it on its own?
any idea?
