Parts needed :
: Arduino uno x 1
: led x 5
: 1k resistor x 5
Step 1: Wiring
Connect all the wire as shown in the figure :
Digital pin 2 to led 1
Digital pin 3 to led 2
Digital pin 4 to led 3
Digital pin 5 to led 4
Digital pin 6 to led 5
don't forget the resister ...!
.............................................................................................................................
Possible improvement
# custom shield for arduino
# adding battery
# adding more led 's
.............................................................................................................................
and upload the sketch and you are left with an amazing pov display...:)
Step 2: Sketch
Change in the " loop " function the text !!!!
