The Word Clock - Arduino version

Step 5 Make the time changing buttons

Next, we need to mount a couple of push buttons onto a piece of board material.  I wired some short lengths of wire to the buttons, ready for connectint to the terminal block on the controller board.

In my case, I used a red and a black button.  I found some ribbon cable that had red and black wires, so I used red for the forward button, and black for the backwards, with grey as the common.

Have a look at the photos to show you how the buttons were connected.

What does the common wire connect to?

[drj113]

the middle terminal of the time set input block (it has three connections - forward, common, and backwards)

[Schmidty850]

yes i understood that, but on the other end like near the buttons

[drj113]

The common is connected to both buttons.  Connect it to one button, and add another wire linking the other button.

Momentary switches? Does it matter?

[drj113]

They are momentary buttons - I just use whatever Pushbuttons I have on hand.

[f2a]

But you would want to use a momentary switch though right? Otherwise if the switch stayed on would the time keep changing? I'm sure I could figure this out in the code perhaps but I'm still learning the basics.

[drj113]

Yes, it *must* be a momentary switch, otherwise the time will keep changing.

Thanks for the reply!
