Arduino Binary Alarm Clock

Step 9 The setting buttons panel

For setting the time I used two buttons, one for setting hours and one for minutes, and one switch for changing between setting the clock and the alarm.

Building the button panel:

My box had a elevation in the middle that the panel could rest on. If your box don't, you can use four wooden sticks or strips taped/glued in the corners of the box and let the panel rest on those.

1. Measure the inside of your box to see how big you should make the panel.
2. Saw out the panel from a piece of thin plywood. To get a good fit, make the panel a bit bigger
    than the inside off the box and sand off the edges until it fits.
3. Cover the board with masking tape and measure out and mark where you want the holes
    for the buttons to be. The tape will help to prevent the edges of the hole to splinter.
4. Carefully remove the tape.
5. Attach the buttons and solder wires to them.
6. Make button labels. I used letters cut out in electrical tape.
7.First attatch the tape to something flat that you are not afraid of scratching.
8. Cut out the letters with an utility or exacto knife.
9. Carefully remove the letters.
10. Attach the letters to the panel.

 If you can get hold of letraset transfer sheets I think that could work even better.

Where are the wires from the buttons going? Great project!

To the arduino, look at the 5th picture in step 14.
From step 3:
"Here are the pins I used for the different parts:

- 2 and 4: Touchsensor (4 is the send pin, 2 is recieve)
- 6 Hour button
- 5 Minute button
- 7 Switch
- 14-18 Display hour pins
- 8-13 Display minute pins"
