Digital 7-Segment Display Counter

Today I've got another project for you - a 1 digit 7-segment display counter. It's a fun little project that counts from 0 to 9 and then back from 0. You can just use it as a general tutorial on using this popular kind of display.

Step 1: Parts Needed

Arduino UNO board
USB Cable
Mini breadboard
1 digit 7-segment display
10 x Jumper Wires

Step 2: Connecting the Display

Plug in the display into the breadboard. You noticed that it has 10 pins. Now we need to connect them.
Start counting from the bottom left, and connect the 3rd pin to the 8th. After you reach the fifth one, continue counting the top pins from right to left. Now, you should connect pin 8 to Arduino GND (-).
Start connecting the other pins - from 1 to 10, skipping 3 and 8, and start from Digital Pin 2 of the Arduino all the way to 9.

Step 3: Uploading the Code

Connect the Arduino to your PC. You can find the code HERE. I've commented some of the lines, so you can understand how the code works. Feel free to modify the code to your desire. If you have any questions, ask them in the comments.

Here is a video showcasing the project:
