So, I’ve graduated. I am single. I have nothing else to do at home except eat, sleep, watch movies and check facebook. Then I come up across this awesome blog by Carlos Asmat which has a lot of interesting stuff. There I find a simple project based on using Persistence of Vision (POV) to create a display (2D) using an LED strip (1D). So I decide ‘Lets do it’ and what goes below is my first attempt at replicating that display. It is still very crude and requires polishing, but well its a start.
Here is a list of parts that went into the making of it:
- Arduino Uno (or any Arduino for that matter, as long as it has 11 or more digital I/O pins)
- CPU Fan (You can find it in any electronics store). The one I have is rated 12V/0.25 mA.
- 9V Batteries
- LED’s (whichever color suits).
- IR Transmitter (I used TSUS4400 from Vishay. You can find it on element 14 here.)
- IR Receiver (I used TEFT4300 from Vishay. You can find it here)
- 220E resistors (for LED’s and IR Transmitter)
- 1K8 resistor for IR Receiver
- 7805 voltage regulator (for giving 5V continuously to IR transmitter. Not needed if you have a 5V or 3.3V battery)
- Some kind of glue (I used Fevistick)
