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
digital seven seg display (SMA420564)
box/enclosure for proeject
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 antunkarlovac.com.
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.
