ITEM NAME:Electronic Dice Kits Suite LED Circuit Kits Stable 4.5-5V Red LED Lights Ga H1H3 Electronic Dice Kits Suite LED Circuit Kits Stable 4.5-5V Red LED Lights Ga H1H3 Circuit mainly by the pulse generator and a decade counter circuit. Pulse generator and external elements by NE555 multivibrator, when you press the button S1 when Q1 turns on, the output pulse NE555 3 feet, then five turns the output CD4017 output high, resistors and transistors by different combination, can drive seven LED light to indicate the number of points 1-6 points. Kit parameters: Supply voltage: 4.5-5V Dimensions: 74x35mm Function play: When a power-up, 7 LED will randomly display a number of points, players press the switch S1,7 all lit LED only after about 7 seconds LED light starts blinking, until finally showed stable points. Throughout the end of the first "crap" process. Package includes: 1 x Electronic Dice Kit Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm..1 x Electronic Dice Kit. Circuit mainly by the pulse generator and a decade counter circuit. until finally showed stable points.
