This should be a LED-matrix :D
My first one - how is it?
Well actually there was one version before with a saving function and a automatic one, and.. others, all went crazy so... this is whats left!
I hope and will be happy about any improvements, comments.. you know :D
The controls under the LEDs:
The 4 ones are there to choose any LED!
They are numbers in binary:
The first two say in what COLUMN the LED is and the last in what ROW.
Example: 1101 means the LED in the 4TH column and the 2ND row.
(Because we begin to count from 0 :P)
Which is the same as the 14th one!
(From left to right, top to bottom)
AND FINALLY the ON/OFF switch at the bottom
Logic behind it:
4Bit input are split in two.
There are two demultiplexers (almost ragequit because there are no ones T.T) which lead the current into 2 outputs from 8 which is there position. The demuxes each have 4 outputs which leads to a corresponding row/column. I designed it so that when you would add a counter (4bit) the LEDs would be switched on in a row. Really simple!
