AVR's & Accelerometers

We got our order from Digi-key today, but unfortunately, we didn't realize the Butterflys didn't come with any of the connection cables, so we haven't had a chance to mess with them yet. Hopefully, we'll be able stop by Fry's or Radio Shack after finals to pick up some parts to make a serial connector for it.

Digikey Invoice

We finally decided on several parts we wanted to use, so we decided to order them last week (see next post). They finally came in today, but I just wanted to post up the invoice for future reference.

*Note: we will only be needing 2x AVR Butterflies and 1x Accelerometer, but we ordered an extra as a back and to just mess around with.

Here's a couple of other projects I found from the link Professor Harris sent us:

Original RC NSX: http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s2003/kw84/Report/documentation.htm
Notes:
-Covers the full design of an RC car
-Includes schematics and parts

Line Following Van:
http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s2007/bl222_wh84/bl222_wh84/index.html
Notes:
-Uses phototransistors and an LED to follow the path of a black line
-Phototransistors can be used to implement the "speed up" functionality

Tilt Controlled Video Game:
http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s2007/cmm98_jl478/cmm98_jl478/index.html
Notes:
-Uses accelerometers to interact with the game

Dual Control R/C Car #1:
http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s2006/acd32ddk26/Antonio%20and%20Donn%20Final%20Project.htm
Notes:
-Uses a dual-axis accelerometer to implement the steering and acceleration of the car
-Can also use LEDs as photo sensors to control the car (may be used for "speed up" functionality)

Dual Control R/C Car #2:
http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s2005/mq23/webpage/index.html
Notes:
-Uses a dual-axis accelerometer to implement the steering and acceleration of the car
-Can also use a computer mouse to control the car
