It should look like this

Next, its time to place the 25V electrolytic capacitor '''C3'''. Electrolytic capacitors are polarized which means they only work well in one direction. Put it in backwards and they can explode! You can tell how to place it because the silkscreened image has a plus near one hole and the capacitor has one long lead. That lead is the positive lead. In this image, its the one on the right.
Also insert '''C1''' which is a ceramic capacitor. Ceramic capacitors are non-polarized so you don't have to worry about putting it backwards

Solder all 4 leads

And clip them short with the cutters.

Next is the 5V regulator. This takes the power from the DC jack which may be something like a 9V battery, and brings it down to 5V, which is suitable for the microcontroller chip. This part must be placed as shown, with the metal heat sink tab on the right.

Turn over the board and solder all three pins, then clip them off

Now you should soder in the 6.3V electrolytic capacitor '''C4''' as shown. Remember its polarized so you must place the longer lead in the positive-marked hole.
Then place the ceramic capacitor '''C5'''

Solder in the capacitors and clip them.
