Introduction: 8 Bits Arduino Binary Counter

About: I'm engineer, I like to design programming things with Arduino hardware and pure electronics too.

8 Bits Arduino Binary Counter van count from 0 to 255. This project is a counter with 8 LED's for being connected to Arduino pin 5, 3, 4, 7, 10, 11, 12 & 13 so that it counts from right to left by generating codes from Zero to 255.

Step 1: Bill of Materials

What you will need:

1-Arduino Uno R3

1-PCB Arduino Mega

1-USB-B to USB-A cable

8x5mm LED

2x5 Array of pins for Arduino

Soldering iron

Solder roll

Maybe a little wire # 22

Step 2: Schematic Diagram

Check carefully, the schematic diagram of your project.

Step 3: Inserting the Array of Pins

Insert the array of pins into the Arduino holes, they should be inserted in the pins 3. 4, 5, 6, 7 and the pins 10, 11, 12, 13, GND.

Step 4: Solder the Pins

Once inserted the pins, proceed to solder them.

Step 5: Installing the LEDs

You can install the LEDs how you want, but this was the array that you did for the project. Even, I used a little bit wire #22 for doing a pair of connections. It can be appreciated on the photos. Note, you can use GND indirectly for connecting the common cathode pins without using solder even on the pin GND to Arduino.

Step 6: Completing the Project

Insert the project into the Arduino pins of your project. If you follow this project exactly, visit:

Then, upload the code at:

but you only do the changes according your own pins used.
