I'm trying to setup the breadboard as shown in the manual but cannot get anything to display. However, the voltage regulator does heat up and I've looked several times and things appear to be setup correctly. Could someone else take a look at it and let me know if I've overlooked something? Yes, the resistor being used is brown, black, and red as shown in the manual. Thanks [ Photos Attached Below ]

It looks like your voltage regulator is shifted one row too close to the MCU. You've got pin 2 where pin 1 should be, pin 3 where pin 2 should be. Just shift it up to the next higher-numbered rows (+1). Take another look at the picture on page 24 of the guide. |

Awesome, the LCD game on and the voltage regulator is no longer getting hot; however, the LCD now shows a series of squares - not a message as shown in the guide... Thanks again |

Hi Devon, Double check your LCD wires. It looks from your picture like only 3 out of the 4 data wires are in correctly. Humberto |

Humberto, you were right (according to the images); the wire had popped out. I have already put it back in place though. :) Any other suggestions? Thanks |

Meh, I was missing the ground wire from LCD pin #5. Thanks again for your help though! |
