Hello, new user here. Microcontrollers have interested me since I was young but I either had no money (when I was young) or school made learning microcontrollers boring (now). But after leaving school for half a year, I think I regained my interest in these and can afford it too. So I'm going to try to build a device for a start. I have some, not too much, experience with the Sparkfun Inventor's Kit when I was in school, mainly input/output, PWM, multithreading and stuff. I think I've forgotten most of them anyway.

I'm going to buy some components, I just want to check with everyone if I'm getting the compatible items. I can only afford to buy them once, as after I get them I'm going to fly off to another country for work (and bring the Rainbowduino along). I'm not sure if I can get more components shipped there.

The end product I'm aiming for would look like this:

So these are what I plan to get:

Rainbowduino LED Driver w/Atmega 328

60mm square 8*8 LED Matrix RGB (Apparently Rainbowduino needs common anode, I think this is right)

9V Battery Holder

5x 12mm Push Button

Resistors (from what I see, the Rainbowduino only takes 2 ADC and 1 PD input, so I guess I'll have to have a button array and use the ADC to measure the resistance and see which button is pressed)

Also, I don't think that any soldering is required right? I'm aiming to do less hardware and more programming for this project, so I hope there is no soldering at all.

I really appreciate your help in helping me verify the components. Thank you very much :)

A potential problem is the Rainbowduino is pretty much geared toward controlling 8x8 LED arrays and has very few (if any) spare pins to allow you to interface things like buttons.

Yes I agree, but since this is a starting project I plan to be simple :)

From the documentations it seems that it has 2 ADC pins and 1 digital. I plan to use the 2 ADC pins to hook up 2 button arrays (of 2 buttons each) and a single reset button for the 1 digital pin.

At least I know I ordered the right components. :)

Thanks.

The link you supplied was for the Rainbowduino v3.0 I think it was the older version that had the ADC6, ADC7 & PD2 pins free. The v3.0 board does break out SDA, SDL, CTS, TX, RX & DTR but I could not find a schematic to determine if these are connected to the atmega chip or some other support chips on the board.
