Step 4: Wiring, the hard part
fist get the battery pack set up
solder two wire leads from ground out and +v out dont solder them together let them hang
ground will have at least 1 lead from every thing soo make the contact long and the + volts wire will be attached to one thing soo does not need to be as long then glue the battery pack to about the middle of the chassis for easy reach.
connect the +volts wire to the middle lead of the switch
then make a base wire (this wire will be how every thing gets power)
this should be bare or almost bare. and connect the base wire to one of the side leads. (which lead you attach it to determines which side is on.)(in other words the side you connected the base wire to is the on and the other is off.) Let me stress that every thing is connected to the switch because the switch is the +volts base. we will hold off on gluing this
u have to test the motors a lot the should both turn the same way and away from the back wheel is forward (obviously) the back wheel is the small wheel
connect the motor to the base +volts wire and the ground base wire test move to next motor then after testing that one and making sure it goes the same way as the other one (if it doesnt switch the soldered wires around) its time to glue them. Glue each motor with hot glue near the front of the chassis and they should be just about even with each other once the motors are glued on u now have a movable vehicle
last but not least the leds
the leds are easy i used a red and green but u could use yellow if u wanted just no white or blue
take the first led and solder the anode (the longer lead, the +volts) to a resistor and solder the resistor to the +volts base. Next solder the cathode (the short one, the one on the flatter side of the led, the ground) to the ground base. Repeat with the other one. and that should be it for the wiring.
where you glue these is up to you but hold off until you put the covering on.
now to glue the switch on
make sure all wiring is complete and every thing (except this and maybe the leds) is glued on, then proceed
put a notch of glue on the side of the battery pack facing forward and stick the switch there
then after the glue has set you could, can, put some reinforcement glue on the switch, I love glue soo i did this.
