Ok so it need a 1K resistor on the Base?

I dont see the problem with the idea? I got it from this:

I replaces the 7seg with led's and hooked the transistors to the 4067.

But like i said i know something is wrong with it, so any suggestions?

Hi, im using 5 digital pins and one 4067 16channel multiplexer to multiplex 16 x 5 LED's. To multiplexer pulls the LED's to ground. (Its for my 16steps sequencer)

The problem im having is that, some led's glow faint when they should be off... I have the feeling im missing some diodes? but dont know where?

here is the schematic, Ow before the LEDS are 220 ohm resistors ofcourse.

I suggest using hex values for start bits and so on. Like 0xF0 (use the hex of a wierd ascii character u never use). Hex works faster in computer world. And easier to work with.

Not very simple but very good.

Yeah i was gonna say CAN-bus aswell. Worked with it at school with a couple of PLC's. Worked fine

Yeah very nice! Would love to see that code for learning!
