Standalone Arduino


This is my first attempt at creating a standalone Arduino. This is using just the bare Atmega238PU without the Arduino development board. I was able to pull the flashed chip from the board and use it. Looking forward to branching out further without needing a full standalone projects. Here's a link to the pin-out I used.

Radio Shack 3D LED Cube



Arduino Liquid Crystal Display


I got my Arduino UNO working with a 1602 LCD display (16x2). Just a simple "Hello World" message and a counter for now. This build uses the LiquidCrystal library from Arduino's website. The library allows you to use any LCD display that is supported by the Hitachi HD44780 driver. The example sketch contained in the library is what I'm using to display "Hello World" with. Thanks Limor Fried at Pro Trinket. All for now.

Arduino LoL Shield Font Demo


Finally got my LoL shield finished.

Arduino LoL Shield Progress


I ordered a LoL Shield from Adafruit for my Arduino a while back. Just now getting around to playing with it. LoL stands for "Lots of LEDs." This shield just attached to the top of an Arduino. With the use of a special library I can program it to display all kinds of patterns or just text. I figured this would be a great project to learn how to solder better. The grid size is 9x14. That's over a 100 LEDs! I think after making 200+ solder joints I should be a pro right? We'll see. Above is my progress so far. It's been tricky to keep them all straight. It doesn't have to be perfect. It gets a little frustrating. I'm enjoying it. That's all that matters.
