Digital Die w/display is a true project of engineering based on JK flip-flops by designing a counter from 1-6 with a circuit clock of variable frequency and a switch normally closed that stops the count when someone pushs its button.

Step 1: Display/decoder Module

Display/decoder module is the monitor of this project. The parts are:

1 Dual PCB Radio Shack 276-159

1 Green Common Anode Display

1 Decoder 7447

7 Resistors of 470 Ohm

1 IC socket 16-Pin

Step 2: Power Supply Module

Power Supply module is to use a 9 Volt battery. In this module, I have included the micro-size potentiometer of 100K Ohm that isn't going to installed on circuit clock but on this module for better connection. The parts are the following:

1/2 Dual PCB Radio Shack 276-159

1 +5V Voltage Regulator 7805

2 Electrolytic capacitors of 100 microF, 50V

1 Battery Clip for 9V

1 Micro-size potentiometer of 100K Ohm

Step 3: Counter Mudule

Counter module is the heart of this project and its parts are the following:

1 Breadboard
2 7476 JK flip-flop
1 7408 AND gate
1 7432 OR Gate
1 IC 555
1 Electrolytic capacitor of 1 microF
1 Resistor of 20K Ohm
1 Slide Switch OFF/ON
1 Switch Normally Closed (Pushbutton)
