Tools you'll need
Get the three 10k resistors. They are the same value so no need to worry about which is which. Resistors are also not polar so there is no putting them in backwards. Bend the leads and place one resistors in each spot labeled with an 'R'. Once the resistors are through the PCB, bend the leads to the side a bit so they don't fall out. Flip over the PCB and solder the resistors. Once all the resistors are soldered in place their leads can be trimmed.
Place the Button and Capacitor. Both of these components are not polar so they can't be put in backwards. Once placed, flip over the PCB. Solder the 4 legs of the button and the 2 leads of the capacitor. Once all the solder joints are made trim the leads of the capacitor.
There are two types of the headers included with the IMU Game kit. One type is to go through the PCB and into the Arduino. The other type of header is for the IMU and that's the one we'll be starting with. Take the 8 pin non-stackable header and place it in the PCB. Flip the PCB over and just solder one pin for now. Once soldered take a look at the header and make sure its straight. If not, reheat the solder joint and move the header into place. Once straight, the rest of the pins can be soldered.
Find the other 3 headers. These are the stackable headers. Placed them in their appropriate spots based on their number of pins. Flip the PCB over and repeat the same process. Tack one pin of each header into place. Make any adjustments if necessary. Then solder the rest of the pins.
The last component is the MOSFET. This is polar so the orientation matters. Place the MOSFET in the bottom middle with the metal side facing away or off the PCB. Flip over the PCB and solder all 3 leads. Once soldered, trim all 3 leads of the MOSFET.
The PCB is all done but before we move on to the Mechanical Assembly, two parts need some work. The first is the vibration motor. First, strip off some of the insulation surrounding the two wires coming from the motor. Next, take about 8 inches of the red and black hook up wire and strip that too. Twist one of the stranded wires together with a wire coming from the motor and solder them to make a more permanent connection. Remember to heat up the wires before you try and apply solder to them. Do this for the other set of wires too.
Now we must do the same thing to the microswitch. Start by taking a new length of the red and black hook up wire and strip a bit off each side. IT doesn't maker which color is used. Feed one stripped end through one of the holes in the tabs of the microswitch. The middle tab will not be used. Apply solder to connect the two. Using the remaining wire, feed that through the unpopulated tab of the micro switch and solder that too.
That's most of the electrical assembly but don't put your soldering iron away yet. We'll need it to solder the other end of those wires.
