I am relatively new to physical computing and as part of an assignment I need to connect AIRRS (Analog Infra Red Range Finding System; from HVWTech) to the BX 24. However, I am not sure how to do this and how can I use it as part of an interactive project. I was hoping that by connecting it to an ADC pin the voltage output (0 - 2.5V) will be converted to digital "high". I think that I don't know how to use it and help will be highly appreciated. Thanks, Isaac [Non-text portions of this message have been removed]

I assume this is the device: http://www.hvwtech.com/downloads/manuals/AIRRS_1_1.pdf Although the manual doesn't say, I'd guess the device is based on a Sharp GP2D12 IR rangefinder. We recently posted a new app note for the BX-24. Check out: http://www.basicx.com/Products/BX-24/bx-24appnotes.htm The file is second from the top of the list. > I was hoping that by connecting it to an ADC pin the > voltage output (0 - 2.5V) will be converted to digital > "high".

The BX-24 ADC pins can all be used for either analog or digital I/O, but for this device, it's not clear to me why you wouldn't want analog input. -- Frank Manning -- NetMedia, Inc.
