Product Name: SKU: 1895 Parsts No. Package: Brand: Quantity: 1, 1. Suite Features Suite Name?Flashing/ Blinking Light Suite Type?YSG-1 Operating Voltage?3~9V ... moreDimensions?30*28mm. 2. Principle of Operating For YSG-1. The Q1 and Q2 form the multivibrator which used to control the flashing of these two LEDs. And here is the operating principle of multivibrator. As there is difference between the components. Q1 or Q2 will be turn on at the first place after the boot. If Q1 turns on at the first place, the voltage of Q1 collector will be 0V and the D1 starts light. As it cannot have a sudden change on the voltage of two ends of the capacitance, the Q1 collector with 0V will let the base potential of Q2 reduced to 0V through C1 and let the Q2 turn off. D2 turns off at this time. When the charge voltage of C1 increases to the breakover voltage of Q2, the Q2 turns on. And the voltage of Q2 collector reduced to 0V and D2 starts to light. In the same way, the Q2 collector with 0V will let the base potential of Q1 reduced to 0V through C2 and let the Q1 turn off. D1 turns off at this time. The multivibrator will operate according to this cycle to let two LEDs light by turns. And the flashing frequency of these two LEDs depends on the specification of C1?C2?R2 and R3. 3.

The function play: Wheel of Fortune is to predict the rotation of the disc to stop. And in the end will stop in which the position of the tool. Also can be used to estimate numbers game, electronic dice, lottery machine. Electronic Wheel of Fortune is in electronic way to reach the same functionality, this package of 10 LEDs configured in a circle, click the button, each LED sequence turns luminous, the flow speed is getting slower and slower and finally stopped at a only LED is no longer moving. The last shiny forecast that LED with players, said that"winning" Circuit: The circuit is composed mainly by the pulse generator and a decimal counter circuit. Pulse generator by NE555 and peripheral components constitute a multivibrator. Press the button S1 when Q1 conduction NE555 pin 3 output pulse, the CD4017 10 output of turns output high drive 10 LEDs turns luminous. The key is released, due to the presence of the capacitor C1, Q1 does not immediately turned off, with the C1 voltage decreased, Q1 of conduction program gradually weakened, 3 feet of the output pulse frequency slows, LED movement frequencies also will slower. Finally, when after the end of the C1 discharge. Q1 off NE555 3 feet longer output pulse LED stops moving. Lottery" process completed. R2 determine the the LED mo
