The Automatic Button Pusher

Step 9 Add Your Trigger Wire

Now we need to run a signal wire from the pin of the microcontroller out to the circuit board we built. I soldered a length of 24ga wire directly to the pin, being careful not to create any solder bridges on the adjacent pins.

I routed the wire out the back where the clock's AC power cord exits.

Be sure to strain relief the wire so that it won't break at the solder joint if it gets tugged on. I simply hot glued it to the circuit board in the clock.
