Okey, I'm going to look for this.The PICAXE Create library from picaxe.com has a download socket component.
• "I can go without less outputs": double negative. Do you mean "I can go without using as many outputs"?I have thought, that if i use a LED DRIVER CHIP I can go without less outputs. Namely, if I don't use a LED DRIVER CHIP I need 4x4x3 = 48 outputs true? (Supposinght that I multiplex each floor, like the 3x3x3 main colour project)
-First, yes. What I want to explain is this, that I can save many pins• "I can go without less outputs": double negative. Do you mean "I can go without using as many outputs"?
• If it's a 4x4x4 LED cube then it will be 4x4x4 rather than 4x4x3. Anyway, you can use shift registers to save on pins but the extra overhead might be too much.
Or would it actually be 4x4x4x3, one 4 for each dimension?Second, I have wrote 4x4x3 because I'm only talking about one floor. And the number 3 is because i think that i have to multiply by three because de LED RGB has three pins.
I don't know if I'm right, I'm only asking.
Yes, I've thought that I could mutiplex for each floor. What do you think? What components I need?Or would it actually be 4x4x4x3, one 4 for each dimension?
Of course, that amount of LEDS would have to be multiplexed.
Sorry, I am not understanding you.Over the top?
Please do not worry.Sorry, I am not understanding you.
The difference is when you have common cathode, the cathodes of the three LEDs built-in are connected together and each anode gets its own pin (i.e. one cathode is common to all) and for common anode it is the other way round (individual cathodes and one anode).What are the diferences?
NPN transitorWhat transistors do you have?
Okey, thanksI'd suggest common cathode
BUT wait for suggestions from the experts before you make any investments.
