Introduction: 10 Bits Binary Counter

This is a binary counter that can count from 0 to 1023 because it's a 10 bits binary counter. However, it needs 10-1N914 diodes like interface between the counter and the 10-10mm LEDs used in this project. The counter is also integrated by 10-JK Flip-Flops; that is, 5-IC74LS76s and an IC555 timer for generating the clock.

Step 1: Bill of Materials

What you will need:

10-10mm Red LEDs

10 Diodes, 1N914

5-IC74LS76, Flip-Flops

5-16-pin, IC socket

1-8-pin, IC socket

1 IC555, Timer

1 5K Potentiometer

1 4.7K Resistor, 1/4 Watt

1 47uF Electrolytic Capacitor

1 7805 Voltage Regulator, +5V

1 9V Battery Clip

1 9V Battery

Some Connecting wires

Soldering Iron

Soldering 60/40 roll

Step 2: Schematics

With the set of schematics included in this step, you have enough information so that you can complete successfully this project. However, you have to make each connection in the first diagram because it's the whole project.

Step 3: Install the LEDs and Diodes

Installing the LEDs, you can connect each other the LED cathodes and solder them too. Remember to mount the diodes with its cathode toward the anode of its respective LED.

Step 4: Complete Your Project

In this step, you have to connect the missing positive terminal of each diode to its respective output of each Flip-Flop by having in count the connections showed in the corresponding schematics. Wiring the whole circuit, you can install everything you need to even install the IC555 because you require to verify the working frequency of your circuit built.

Step 5: Install the IC74LS76

In this step, you can install the rest of integrated circuits.

Step 6: Install the Battery

Once installed the integrated circuit in your new project, you can connect the 9V battery so that you can see its functionality.

Nice circuit! I would suggest to replace the 1N914´s diodes with 220 ohm resistors. That will protect the LEDs and the battery will last much longer.

CD4040 cmos IC provides 12 flip-flop outputs on a single chip, and you wont need the 5V regulator at all.

greetings!

Nice to see someone still uses DIP chips to make things. Usually it is Arduino designed and built. But this will allow you to understand such circuits better in my opinion. Nice build...
