No, it that something I need to do first? I don't really know much about that.

I've got an ATmega328P on an UNO and I'm trying to burn the lilypad bootloader onto it, to use on a breadboard. So I select "Lilypad Arduino w/ ATmega328" and try burning it with any program and I get an error. "Content mismatch" or "protocol error, expect=0x14, resp=0x51". Errors with any program. So then I try "ATmega328 on a breadboard (8 MHz internal clock)" from http://arduino.cc/en/Tutorial/ArduinoToBreadboard and I get the exact same errors. Is this a 328/328P thing? I'm having trouble finding anything that make sense on google. I would appreciate any help.

Thanks

Okay, cool, that makes sense.

Actually, I have another question. If the Nixie tubes are using approx. 200 volts, how can these 74HC595 IC's handle them? How to you wire them so that you don't blow up your 74HC595?

Perfect, thank you. Although that seems pretty complicated. Ill try to make sense of it when I begin working on things, but in the meantime if anyone has any more help or tips i would appreciate it.

Thanks guys, Ill look into RTC's.

I've ordered a couple IN-16 Nixie tubes and a small set of 74141 drivers. I plan on using the guts of a disposable camera to power them and I'll be running it with my UNO. I'm pretty new with Arduino, I was wondering, since each nixie tube will need 4 pins from the 74141, how to I deal with not having enough outputs on the board? I understand how to binary and HIGH/LOW to control one 74141. I assume I need another driver between the Arduino and the 74141's. It would be nice if someone could explain how to deal with this in detail for when I plan on using more tubes.

Thanks

Well, all I really am looking for is the most basic, form of time keeping that can be programmed.

I want to eventually make a clock of some sort. Right now I simply want to understand how to keep time(I know that it would need to be set at startup but right now I'm not even worried about that). The examples in the Time Library all return errors for me like "'time_t' does not name a type" among many others. I was hoping for some help on this or an example of the most very basic way to keep accurate time on the arduino uno.

thanks
