i will have a matt this mat will have pads that hook up to the cubes and the cubes them selves will have magnets so i cant hook it up wrong and pads on the top to transfer power to the next one. the cubes will only hold a transistor (so it will only take the power it needs and sends the rest to the next one) and leds. the mat will also be using my power for leds project.
the 4 modes the mat will have is
off
on - adjustable brightness
blinking
music
(any ideas for what else)the mat will look like this on its top
-------------------------------------------------------------------------------
audio plug ]
(on off lever) ( brightness adjusting wheel) blinking/music switch ]
-------------------------------------------------------------------------------
the true size of that will actual be like 1 inch wide and 4 inches long
with an actual plastic mat with the pads for connections
power supply has not been decided yet
led's
Max. Forward Voltage: 3.0-3.4V
Max. Reverse Voltage: 5V
Max. Forward Current: 15-20mA
Max. Reverse Current: 15-20mA
can i use a resistor pots like this to adjust the brightness (same for the blink and music)

take the led an battiery out of the picture
