Arduino and Stand Alone Wii IR Sensor
April 28, 2010
Hey everybody, I am looking for help with this project: http://letsmakerobots.com/node/7752
I need to make a device for a school project that detects IR position for a PC mouse but that incoporates a
microcontroller, so this project seems like a good start.
I have already built the voltage regulating circuit, removed the IR sensor and attached it to the circuit. All
voltages seem to be at desired values.
But I have a strange problem. The project calls of a Duemilanove board, which I have, but the tutorial does
not tell you how to connect the circuit to the board. And the attached video does not use the board at all.
The tutorial links to a German wiki that says to connect SCL to PC5 (I assume that would be Analog Pin 5) and
SDA to PC4 (I assume that would be Analog Pin 4).
So I do this, but the board stops transmitting as soon as I plug in SCL and SDA. In the Arduino IDE serial
monitor, a bunch of zeroes are displayed using the provided sample code. Same goes for hyper terminal in
Windows. The zeroes stop coming as soon as I plug in SCL and SDA, and the zeroes resume when I disconnect
them. Additionally, the voltage at the SCL and SDA pins drops from 3.3V to 1.8V (on the circuit).
I get no blobs using the Wii-Blobtracker software provided in the tutorial.
The only thing I can think of is that maybe I fried the sensor when I removed it from the remote? It looked
fine, is there any other way to tell for sure?
If anyone has any experience with this project, I'd appreciate any help.
Thanks in advance.
