How do I right to a 556-ATMEGA48-20PU

Hello I have little active knowledge of electronics,I have always wanted to develop skills in this area. I have set myself a task , Which I hoped was achievable when I set it but have come across one or two problems. My current goal is to use the indestructible link (Infrared Proximity Sensing Coffee Table Module & Color Changing Glowing Faucet) to create an interactive artwork for kids. I can get hold of the parts, and put them together, The programming looks to be correct. But I cannot work out how to get the programming onto the chip. What sort of equipment I would need ect ect. I suspect this is all basic stuff but as a fella with high school summer jobs as my experience I am struggling to find the answer for myself. Any help would be greatly appreciated. Kind regards, Phil PS the chip is an

Hi, Phil:

You have a terrific idea, but unless you have a bit of electronics background you might want to work up to it.

My recommendation would be to get an Arduino Uno and learn it first .. there's some pretty good tutorials at adafruit (http://learn.adafruit.com/category/learn-arduino) that will help you get started.

Once you've gotten the hand of it, then you'll probably have a good idea of how to approach your project.

Let me know if there's anything that I can do to help..

Regards,

Bruce

I would agree with Bruce. The Arduino would be an excellent starting point.

I agree with Bruce, pick up an arduino and try it.

If you need help with the programming just ask here.

Take into account that a Arduino board is just an ATmega chip on a development board so you can use that same program modified, if the board you get have enough i/o pins. You just need to translate the pins from the program you've got to the arduino pins.

Those are the arduino Uno pin mappings http://arduino.cc/en/Hacking/PinMapping168

The outer red ones are the labels on the arduino board, the inner black ones are the ATmega pin names. If you check the instructable source code you will see the ATmega pin names he is using.

The programming environment you see in the instructable - avr gcc and programmers notepad - is included - but somewhat hidden in the tools directory- on the arduino windows SDK.

It's a hard project to start with, but you can pick up an arduino go for it while learning a little more.

Anyway, to program the ATmega directly I use my AVR Dragon with a ZIP socket.

Exactly the same programmer used in this instructable Help: An Absolute Beginner's Guide to 8-Bit AVR Programming-AVR Dragon : How to Prepare the AVR Dragon for AVR Programmi…
