Digital Clock!




Introduction: Digital Clock!

I will show you how to make a digital clock with an arduino.

Step 1: Materials

arduino uno r3

assorted jumper wires

USB 5v battery pack

USB cable

digital seven seg display (SMA420564)

box/enclosure for proeject

solderless breadboard

push swithces

Step 2: Arduino

Any of these online will work, so get one to run your project. Buy one at an electronic store.

Step 3: Battery

A USB pack can be about ten bucks at a hardware store or on Amazon.

Step 4: Wires

A good jumper cable is compatible with an Arduino, so get these cheap off of Amazon or hardware store.

Step 5: Programming

To complete programming, find the program(s) off of GitHub. The wiring will be available at

Test the project as needed, and edit.

Step 6: END

Enjoy the project and please comment below. Sorry if the steps weren't that detailed. Antun Karlovac's website deserves credit. Thanks, and please tell me how to improve.

    Thanks for sharing your clock!

    My suggestion would be to always include a wiring diagram in one of the steps. Those are very helpful with projects like this. Otherwise, not bad for a first instructable! :)
