Kit Model: IDC-7
Supply voltage :4.5 - 5V
Dimensions: 74 (L) * 35 (W) mm
Board FR-4 military grade A material
1. Many soldering pads do not come off easily
2 becomes less likely to occur from the bending (refer to the non-human case resulting bending), poor sheet with time and changes in the environment arising from bending.
3. Impedance more stable and reliable
4. Plating tolerance and stability of some of the parameters, A material was very powerful interests in relative to some other sheet metal price of money.
Players by pressing S1, to simulate the "dice", the number of points obtained by seven LEDs to indicate the same kind dice, instructions 1-6 points.
Power Supply Voltage£º4.5£5V Dimensions£º74*35mm
Operating£ºSeven LEDs will display a number of points randomly when it's on. After pressing S1, seven LEDs light up and start flashing for few seconds. And it ends up with displaying a point in a stable way.
Principle of Circuits:
The circuit is mainly composed of pulse generator and a decimal counting circuit. And the multivibrator is formed by NE555 and the peripheral components. After press S1, Q1 is on and PIN 3 of NE555 outputs the pulse. Five output ends of CD4017 output the high level by turns. Seven LED light up and indicate 1-6 points with the results of the different combination between resistors and transistors.
