Note: The resistor tells the microcontroller not to reset once the power is turned on, so your game can
continue uninterrupted. Try to be gentle with the board, but a few scratches are not a big deal.
Capacitors
Locate the two 0.1uF decoupling capacitors. These look a little different than resistors. They have two leads than
come down off the bottom of the component, and they have the markings “104” on them. (also note, the bottom
side may have some other letters, like “K5M”). They look like this:
Locate their positions on the PCB:
Insert the capacitors, flip the board over to the bottom side, and solder the pins just like the resistor.
Note: The decoupling capacitors help "clean up" the power on the board.

Component
Pay special attention to the component’s markings indicating how to place it on the PCB.
Polarized components can only be connected to a circuit in one direction.
