Joanna This was fun, I need to make some sound with the PIC next though.

Aaron This lab went smoothly now that I got a new breadboard It was ncie being able to have things change over time with the pic. I need to do some stuff with sound though still, i dont quite see what component I need in order to get sound to come out of the pic. Is it the midi clip? I thought it was just a phono jack of some kind. Oh well, maybe later on in the week. I am still waiting to get an RGB LED as well, and have thought up some cool applications i want to try out, maybe doing some video sensing and low rez imagery in RGB LED on set of bread boards and pics...and LED tv monitor sort of I guess. We shall see.
Bennett - This lab was like sweet nectar after that unsucessful serial debaucle last week. But I guess I've been wanting to make sound with this microcontroller since we got started. I picked up both the 8ohm speaker and the audio jack at Radioshack. I followed the code on the site, and it went fine. I was a bit confused in the FREQOUT syntax where it said that while "pin" was the port you wanted to be the output, it could also be a variable. I just assigned it to the correct pin and it worked fine. I had the most fun making both of the frequencies into adcVar, and toying with the duration to get different effects. I found that lower numbers, i.e. shorter cycles, gave cool harmonics as I slowly turned the pot, whereas higher numbers gave nice pulsing beeps that would slide up and down the scale. The PIC doesn't seem capable of generating a really 'pure tone' but I guess that is because its really 'faking' analog out. The 8ohm speaker gave a barely audible tone, so I piped it through a computer speaker, and recorded some of that in Garageband. I'll post an mp3 in my journal along with some code. I did some of the NEXT FOR PWM stuff. Got the LED to do the "apple sleep" pulse nicely.
Mikro Mike - Though Outcast's "Roses" would have been more appropriate for my feeling about Hallmark holidays like today (Valentine's), I was content to make my PIC chip play "Mary Had a Microchip" (or a "Little Lamb", whatever). Code and Audio/Video are here http://www.mikereger.net/ITP/archives/2006/02/pcomp_lab_4_ana.html
Joseph - Lab4
setting it up: easy.
pluging it in: painful (do not plug your PIC into the power with headphones on).

Won week 4 lab
Viviana - I basically was not able to get this stuff to work. I keep spending several hours on it without any luck, it seems to be very simple, and I am disconcerted that I was not able to get it to work, it seems to be so easy when done during class. Frustration....
