pov display

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

// how long each led stays on for
int delayTime = 4;
//how long between each 
int charBreak = 3;
//how long to wait after the message is finished before it repeats
int resetTime = 20;

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