Arduino with LCD Smartie and HD44780 4x20 display
Loading...
Uploaded by fshanahan on Nov 23, 2008
Here's an Arduino connected to a 4x20 HD44780 display, enclosed in 8"x4 1/2" Lexan. I used a modified version of the LCD arduino library and hacked the LCD Smartie Sketch using Orbital Matrix commands. LCD Smartie is running the BigNum plugins. It shows Facebook news feeds, BBC Headlines, a Clock, local Weather and my Folding at home status (team 144824).

Ouch, nasty ghosting!!! Nice set up though

Thanks. The ghosting is just a video artifact, it's not really visible in real life.

this is a nice setup, but isn't it simpler just to connect the display straight to the pc and control it directly using a software? what is the benefit of using the arduino for this purpose, or is it just a proof of concept? thanks!

Yes, absolutely, this could've been connected directly to the parallel port. I just did it this way to use a USB port and the get familiar with the arduino. See my follow up project which is a more complex LED matrix using an RGB matrix with 192 LEDs.
