pov display

here is an exciting project for you all pov display this project will
float words in air and easy to made

material needed:-

• Arduino nano (but can use any arduino)
• 5 leds
• 5 220 ohms resistor
• jumper wire
• battery
• vero/prototyping board
• switch (if needed)

instructions:-

• 
  

  first connect leds to vero/prototyping board

  
  connect the led to vero/prototyping board be careful that the led should be connected to
  digital pins 8,9,10,11,12 of arduino
_________________________________________________________________________________________
• 
  

  after fitting leds to vero/prototyping board cut the excess board

  
  cut it by using a sharp knife or scissor.

• upload the code on the arduino

I suggest you that to use this device you should have a strong hand because you have to shake it
