 Assembly:
-Insert resistors and capacitors as labeled - solder connection on the bottom. Trim excess leads.
+Read all of the steps before assembling so that you know what to expect.
+Note: The current steps instruct you to solder two 9 pin male headers after soldering the 8x8 LED Matrix. However, in practice you may find that this does not leave much room for the soldering tip to reach the header pins.  It may work better to solder the header pins before soldering the 8x8 LED Matrix.
+Try place the parts onto the board and see what order gives you the better clearance for attaching all the components.
+Insert resistors as labeled - solder connection on the bottom. Trim excess leads.
 Insert LDR in oval spot next to 10 k resistors. Solder connection on bottom. Trim excess leads.

 Insert 8x8 LED Matrix with the black writing on the edge of the Matrix facing downward to the bottom edge of the board - NOT facing the capacitors. Solder connections.
