Step 6The famous third connection
Here is the principal and most important thing about the beetlerobot.
It is call the "third connection"
In you AA battery you have 2 wires that provide 3Volts.
In reality, we only use 1,5Volts for both motors.
How can we get half the voltage? simple, you solder a wire like the picture below.
I solder a 2 inch long blue wire.
simple hey!
don't forget to browse the other pictures to see.

Soldering is defined as "the joining of metals by a fusion of alloys which have relatively low melting points". In other words, you use a metal that has a low melting point to adhere the surfaces to be soldered together. Consider that soldering is more like gluing with molten metal, unlike welding where the base metals are actually melted and combined. Soldering is also a must have skill for all sorts of electrical and electronics work. It is also a skill that must be taught correctly and developed with practice. from http://www.aaroncake.net/electronics/solder.htm

It's not to save power, each motor only uses 1.5v, if you have two AAA's which have a total voltage of 3v then you split it in half to run the two motors.
