Step 3Making the connections
When connecting the LEDs together make sure that red wire is connected to the longer leg of the first LED and that the short leg is connected to the long leg of the next LED. The sort leg of the 4th LED will be connected to the black wire. Make sure you only use four LEDs (two for each side of the sensor bar) otherwise the LEDs won't be bright enough or may not light, unless you wire them differently, but we will keep it simple.
If you are using alligator clips all you have to do is clip them on. Simple.
If you are new to soldering, make sure you have a damp sponge to keep the tip of the iron clean. Also be extremely careful not to touch any of the medal. I recommend soldering over cardboard that way if any solder touches it it won't stick easy. Just simply touch the wires together, put solder to it, and melt it with the soldering iron. The solder should stick to the wires. Also, try not to inhale the smoke.
