My parts arrived. I got the Micro SD Shield from Sparkfun. After following the Quickstarter Guide I was on my way to logging data. I started by loging the amount of sunlight that hit my desk. After finding a batter for my arduino I was able ti log the sunlight on my porch. Although most sd cards use pin 10 thris shield uses pin 8 for card select. It does mean that you have to convert thr code over, but most of the time the chip select worked as pin 10. Still a mistery for me,
A few years ago (2006?) my Dad bought a robot. It was really cool and was controlled by a computer. The robot used treads to move and an Xbee to receive commands. After a while it was put in a box and we moved to a new house. This past year I found it again and tried to get it working. The problem is the company that made the computer software that runs it it gone. My solution, an Arduino.
After a few months I was able to send programs to the Arduino that then made the Robot move. I also learned about drivers (chips that turn control signals into motor movements) and how to program with functions. (lines of code that refer to other code, ie if i say do X, then it finds the line of code that says what X is). They save a ton of room.
Now that I have the code for serial communication an Arduino Esplora remote controler isnt far away.
This weekend while picking up some parts at RadioShack I stumbled upon a 3D Led Cube Shield for Arduino. The instructions are very detailed at first then as you go on you have to start problem solving. My favorite part is that the layout for the leds is drilled into the shield. You actually use the shield as a layout for the leds! How smart is that.
To get the sketch for Arduino to run the Led you have download the Support Files. The included sketch has a lot of examples and does a good job of describing each part. Although it will still be awhile until I'm able to write my own from scratch.
