Night-Owl Alarm

Step 3 Spell out the word "SAFE"

Okay, now what you're going to need to do is to write out the word "SAFE" across both of your 2-digit 8-segment displays. You should do this on your breadboard first to make sure that it is right. V+ should go to two pins in the top middle on each of the segment displays. By connecting ground to any other of the pins you should light up a segment on that display. See the wiring diagrams below.

Once you are sure that the wiring is right, you could remove the segment displays (leaving all the wiring in place for reference). Now start soldering the displays into the Grid-Style PC Board so that the top of the display allows for the connection of one wire in each of the registers. Don't worry about the bottom half. The bottom half is a bunch of connections that essentially are connected to ground. The approach for this is to bridge all ground connections with solder and then bridge these connections to the middle register. The V+ connections are grouped in two sets of two on the top and should be bridged together to make two sets. These sets should be connected to each other via a wire on the top and then connected by another wire to a register on the side of the board.

Now connect a long red (V+) and a black wire (ground) to the display. These are the wires you are going to use ultimately to power the display and should be long enough to pass through the owl.
