	We start with soldering the 555 Timer IC. For this, first think about how it has to be placed on the PCB. The area should be relatively easy to determine, you can do this either by the form of the pads where the legs will be soldered to or by the name: The place is marked "U1".

	Join the long leg with one end of the red wire by heating up the speaker pin and holding the red wire to it. Do the same with the black wire and the short leg.		Join the long leg with one end of the red wire by heating up the speaker pin and holding the red wire to it. Do the same with the black wire and the short leg.

			You should now have a speaker with two wires, a black and a red one. Solder these to the PCBs at the SPEAKER connector. The correct positions for black and red are marked on the back side of the PCBs with "black" and "red". Alternatively: The red one belongs into the hole with the square pad and the black one into the hole with the round pad. Solder them there.
