Connect the DC connector wires to terminal block K2. Watch the polarity! Connect the push button
to S1 and connect the buzzer to Bz1. Watch again the polarity!
If you are using the backlight PCB, connect it to K1 on the main board using the 3 pole socket
headers and wires we prepared a few steps earlier. Take care that the connections D, 0 and + on
the backlight PCB are connected to the same D, 0 and + pins of connector K1 on the main board.
You can now test your clock again if you wish to do so.
The construction of the electronics of your clock
has now been completed. Please read further, if
you want to put the clock in the acrylic
enclosure from Elektor.
