perhaps your easiest solution is to use a 9volt battery and connect up a 7805 regulator to your circuit.

The regulator has three connections:


Ground connects to your ground connection of your circuit and the -ve of the battery, input connects to the +ve of your battery and output connects to VDD of your circuit.

It gives you a nice steady 5volt output

right now i only have 3 volt battery and it seems to work fine. could there be a problem with it?

I'd certainly recommend running at 5v otherwise you could get unwanted / random results.

The pickit2 is perfect for this because it can power it and program it for you

seeing that picture reminded me of something in an old VHS player i was pulling apart so i went and soldered it off. the problem is that instead of the metal top its plastic so i asked my dad to make sure it was a regulator and he said it looked like a transistor. i googled the label 'ST u748 malaysia p3n60fi' put only found stuff about cars
its not what i need but its just out of curiosity.

Searching google for p3n60f1 reveals that it is actually a FET (field effect transistor)

More specifically it is a FET rated at 600V, 2.1Amps

You will find that there are loads of different components all made into a similar package

im making that christmas card game santas scramble from instructables and im trying to get the code onto the pic but i cant find out how to open it on mplab. when i select open it just dosent show the file.

i think what you're looking for is the assembly code

Here you go!

thanks that helped one other thing i was trying to find the layout for my led matrix and i typed in the text at the bottom and i couldnt find anything...any1 know?
led text = tom-1088degc-b 33 4(?)p

Could you post a picture of it, I am quite sure it would be the same pinout as the ones I use.

is this what you wanted?

lol how do u make them smaller everytime i post pics they are so huge

I have resized your images for you

just get yourself an image resizer program, you can get them for free (look at making them no wider than about 600 pixels)

Your pinouts would certainly be the same as the ones we all use around here, check out this topic - it gives you all the info you need!

thanx for that it helped....im making a pcb bourd so i can just plug in the chip and the plug and be set. what i was wondering is all 18 pinned chips wired up to the pickit 2 the same?? and what about the larger chips?

I would say most of the 16F series 18pin microchips by microchip would be the same but it still depends on what Peripherals the microchips have, you will still need to check the datasheet. the same goes for the bigger 28 pin, 40 pin microchips etc...
