Electronic DIY Kit Dice NE555 CD4017 DIY Kit 5mm Red LEDs 4.5-5V ICSK057A Electronic Fun DIY Kit

ICSK057A Precise Electronic Dice DIY Kit 7pcs 5mm Red LEDs

Electronic dice kit is based on the NE555 oscillator circuit and circuit CD4017 counter display kit.
Can simulate the dice, get fun of the game.

1. Kit parameters:

Supply voltage: 4.5-5V
Dimensions: 74 * 35mm

2. Function:

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.

3. Circuit:

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.
