V DC voltage provided to Mother board using 5 V regulator circuit. Mother board will provide the input voltage to Daughter board. 500 mA current supply provided to mother board to get all components to a perfect working condition. (propeller_posn==40) Here a major challenge that we faced is the connecting +5V supply to the rotating circuit. We tried the various methods to do that. But finally we choose a method, as shown in the above figure. Conventional methods of displaying images or massage to public are using LCD display and dot-matrix LED displays. Propeller LED display is a special kind of device that project an image, text or time as if the images are floating in the air. Actually the floating images emerge by synchronizing LED’S blink to form an image at particular time and rate.

This code will display RS232 ASCII transmissions from a PC and display a scrolling message board. The following picture shows an example "Hello World!" message, but it does no justice compared to the video below. The Arduino code could be modified to do things like the following:epoxy adhesive on the four legs. Connect up the two motor supply wires to the corresponding solder pads (J6), with the positive pole to L4 and the negative to Q8.

If you come up with any interesting modifications then I will gladly post a copy or a link to your new sketch with credits. http://people.ece.cornell.edu/land/courses/ece4760/FinalProjects/f2012/cfz4_sjh234/cfz4_sjh234/FinalProjectDocumentation.html So, if someone is observing the images at least 16 frames per second, then they appear to be continuous. For example, if we want to display ‘1’, then the series of lighting up of LED s would be like bellow.

Display fixed message strings without needing the FSK circuitry or a PC transmitting over RS232 (there is a commented out snippet of code in the example to do this). (propeller_posn==35) (propeller_posn==25)

(propeller_posn==5) UK Next Day Delivery - this excludes Northern Ireland and the Scottish Highlands, plus Orkney, Shetland and the Western Isles. Delivery to these locations will be on a 48 hour service. (propeller_posn==30) Insert the Blue Led above the green led as shown in fig (Blue LED 17 via R17 and A7). Connect R17 as 2.2kΩ and join the cathode of this LED to the cathode of other LED’s. Now, connect the positive leg of this Led to one end of the resistor R17 and the other end to the Arduino +5V pin. tape, which no longer serve any purpose. You will now be able to hold the inner layer in place with a few spots of glue. Now insert the resistors and bend its leads the same as you did for LED’s. Cut the extra leads accordingly.

ATmega32A has an 8-Bit Processor and it has 32K of program space, 32 I/O peripherals. It runs up to 16MHz with external crystal. Flip the pixelmap for the message board to be readable at the top or bottom (there is a #define constant already in code to select). Bend the LED strands as shown. It is very important to bend the legs exactly as shown, or the positive and negative can get mixed up.

This is the phenomenon which is related to vision capability of human eye by which an after- image is thought to persist for approximately one sixteenth of a second. Before cutting any strands, make sure the LED's are all straight. if a few seem crooked, just apply heat to the solders you made to straighten them out. Careful not to burn your fingers! (propeller_posn==55)) Remove the Arduino programmer and apply power to the POV base and motor. That's really all there is to it!
