THE DEVIL SUGGESTS
Build a digital clock from components
Build a clock that tells the time using a display, a controller and your own code. It is a compact introduction to wiring, timing and making an object you will see every day.
Do it
- Choose a display and a suitable microcontroller.
- Connect the display and show a test message.
- Add a time source, such as a clock module or network time.
- Program a simple, readable clock face.
- Put it in a case or stand and check it keeps sensible time.
What next?
Keep the useful notes, photograph the result if there is one, then go and find something else to do.
