Step 1: Wiring

Picture of 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

I made it! But I have a question, do I have to move the leds in a single direction or both directions?

how did you compute the value of the letterSpace and dotTime variables?

It's really easy and works fine.... Thax Glen.

Can i apply the same code to make a POV with 7 LEDs on a rotating base like of motor?

Would i need to change the delay between letter?

I started with your 5 LED display and built on that to make my globe. Thanks for sharing. Also, thanks to SintaxGamer for sharing the 0-9 digits. I'll see if I can run both loops to display text on the globe.

very nice code, took the time to add 0-9 :)

int ONE[] = {1,0,0,0,1, 1,1,1,1,1, 0,0,0,0,1};

int TWO[] = {0,1,0,1,1, 1,0,1,0,1, 0,1,0,0,1};

int THREE[] = {1,0,1,0,1, 1,0,1,0,1, 1,1,1,1,1};

int FOUR[] = {1,1,1,0,0, 0,0,1,0,0, 1,1,1,1,1};

int FIVE[] = {1,0,1,0,1, 1,0,1,0,1, 1,0,1,1,1};

int SIX[] = {1,0,1,1,1, 1,0,1,0,1, 1,0,1,1,1};

int SEVEN[] = {1,0,0,0,0, 1,0,0,0,0, 1,1,1,1,1};

int EIGHT[] = {1,1,1,1,1, 1,0,1,0,1, 1,1,1,1,1};

int NINE[] = {1,1,1,0,0, 1,0,1,0,0, 1,1,1,1,1};

int ZERO[] = {1,1,1,1,1, 1,0,0,0,1, 1,1,1,1,1};

Thanks for share.

It's very simple & interesting. ^^

r have clock time ? help code ?

Nice and simple. I am going to try this with a nano. Make it compact and easy to wave around. Thanks for sharing.

Thanks for share.
I think there is a mistake in wiring diagram. The resistor should be in the negative leg (shorter leg) of the led.
Regards.
What difference could it make? It's in series w/ the LED.
Thanks for the tutorial, it helped me a lot.

Thanks...:)
which Arduino uno u used
Arduino Uno Rev 3
usb or plug Arduino Uno Rev 3
how to program it?
Which arduino?
usb one or plug.
how to program it and where is the third step.
which type of Arduino Uno Rev 3
i)usb cable
ii) plug
Thanks for posting, I was looking at the sketch, its a bit like that movie, you look at it long enough you can see the matrix.... or maybe I just need glasses :-)
Glen P Yeldho (author)  liquidhandwash1 year ago
Next time ,I will make a code searching glasses.....:)
