Step 6Wires
Solder the wires coming from the leds and the button to the microcontroller.
The led first led (the led farthest down) is the Minute-1 led up to the led for Minute-32 that should be just beneath the microcontroller. Above the microcontroller is the Hour-1 led.
Don't forget the wire coming from the button, solder that to pin 11 on the microcontroller.
End with soldering the power wires to pin 20 (plus) and pin 10 (minus) on the CPU. And yes, there's one final wire to do - solder a wire between the pin 10 on the microcontroller to the long wire connecting all the leds (and the button).
Finish it off by using hotglue to hold down all the wires into the trenches in a neat and orderly fashion.
