Led microcontroller for thickos?

[jimcanswim]

Hi, I am trying to build my first little project and I want to have upto 56 leds each with their own characteristic flashing sequence.

Is there any standard microcontrollers out there that I could use? The thought of building a microcontroller scares me.

Thanks

You can use any µC with at least 15 free I/O ports. Use them as one 8 bit port and one 7 bit port and use multiplexing to drive the LEDs in a 7*8 matrix.

See this reference.

Wow that reference you sent was awesome, where do I get something like that?

Do you think I would be aple to have flying leads to the LEDs which I want to mount on a separate art piece?

I didn't understand any of the tech speak as I'm a noob, so please be gentle and speak slowly

Buy the kit right there.

I don't know. Are you able?
Of course you can do that. It just takes some careful work to connect all those wires correctly.

 

[jimcanswim]

I mean, can you pull the leds out or are they soldered in place?

 

[Harald Kapp]

You'll have to solder the kit yourself. So don't solder the LEDs into the PCB in the first place but use wires to connect them. May look a bit messy but possible.

thanks for that. Do you know the physical dimensions of peggy?

Did you read the ref webpage? It is there.
