About this deal

(propeller_posn==10)

LED module consisting of 10 bright red color LEDs and it is fixed in corner of the arm of the propeller. It is a main part of the circuit. LED module is used to displaying the characters and symbols. These 10 LEDs are connected with each pins of the port A and two pins of the port B of microcontroller. Phototransistor

V DC voltage provided to Mother board using 9 V regulator circuit. User can plug a 9Vdc-24Vdc range DC power supply as the power source of Motor. Minimum 500mA and Maximum 1000 mA current supply must provide to Motor to get a proper rotation speed. 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. if ((propeller_posn==0) Display pixel graphics transmitted from the PC. Instead of translating a RS232 character as an ASCII bitmap, the RS232 character could potentially represent pixel values in a column. A PC running software (C code, Python or your favorite script, LabVIEW, etc.) could translate images into RS232 messages that this display could show. Choose one end of the Pcb board to work with. On this side, you will place the first LED in the 7th hole of the first column (see photo). Place the rest of the LED's as shown. When placing LED's in the holes, the positive end (the longer metal leg) should go in first. See the picture for reference.

(propeller_posn==15) (propeller_posn==25) The same way, insert the remaining Red LED’s (LED 1 – LED 11 via R1 to R11 and D2 to D12 respectively).delayMicroseconds(450); // for the gap between LED pixels/minutes markers (change the value according to motor speed. Increase for low speed, decrease for high speed motor) An Infrared LED (IR), also known as Infrared transmitter, is a special purpose LED that transmits infrared rays with nanometer range of wavelength. IR transmitters along with IR receivers are commonly used as sensors. The appearance is same as a most common LEDs.

The transformer primary will then be glued to the board on the other side, around the motor. Before 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. 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). The motor/secondary assembly can now be inserted into the base unit. It will be glued using a few drops of (propeller_posn==40) The first prototype was built using magnet wire for the spinning air-core transformer. 28 gauge wire was used in the handmade prototype. 28 gauge wire has a cross-sectional area roughly equal to a 1oz 100 mil wide PCB trace. The actual PCB used 10 mil wide trace for lower current by taking advantage of the ~4 ohm equivalent series resistance (ESR) of the PCB trace at the cost of lower power transfer to the secondary board.

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.

This devise can be modifying as a computer based display board. A wireless system can be used to communicate between the PC and the device. This would let the user to display any massage easily on propeller display. (propeller_posn==35)
