/Persistence-of-vision-stick

This project involved a set of 8 LEDs and a microcontroller mounted on a base. The base can be place on any rotating platform to display pre-programmed text. The microcontroller calculated the rotation velocity using the IR-sensors and sends appropriate commands to the LEDs to display patterns.

Contribution to Database of structure of characters by- Sri Harsha Grandhi Anurag Anand KAtivarpu Parthiv

Contribution Mechanical Structure assembly , balancing and improvement by- Anurag Anand Parakh Gupta

Materials used :

8 - green clored LEDs 1 - Serial in- Parallel out shift register 1 - digital ir Sensor 1 - motor (rpm = 1000) 1 - on board 5v power supply 1 - arduino

Note -

  • the LED to be glown in a frame were sent as data using SPI comm protocol using slave select pin as the latch, and utilizing only MOSI.
  • IR sensor was used to detect the position of completion of one revolution
  • by canging the delay 'd' in given code the width of characters can be changed
