It's time to put the ICs on the board for the last time, to prepare for the final testing.

Parts Needed

  • 1 x Graphic LCD1 x Parallax Propeller
  • 1 x LM339 Quad Comparator
  • 1 x 32kB EEPROM
  • 1 x LM386 Audio Amplifier

Instructions

Now we can seat the LCD.

  • Install the four standoffs onto the board.
  • Line up the LCD so that its 20-pin header will attach to the 20-pin socket. Then put the header into the socket. It will not go in all the way; that's okay.
    INSERT LCD SEATED CLOSE UP ON PINS
  • Place screws in the four corners of the LCD and tighten them into the standoffs.
  • 1 x Thumbstick cap

Instructions

  1. Go ahead and put the Propeller, LM339, LM386, and EEPROM back into their sockets for one last time. It's almost show time.

    Warning

    Do not put the ICs in backwards!
