Bedchamber is not a common word in the US and it means bedroom
When I first read the title of this
http://ijircce.com/upload/2014/april/19_AZigbee.pdfmy brain read "bedpan" not "bedchamber"
So I glanced over the article seeing temp, light, and fan. Then I tried to figure out what the temp of poop had to do with anything. Light maybe turn off and certainly a fan but temp ? I thought maybe they wanted the temp to go down before an alarm went off. Or a high temp meant there was something there. ??
After reading the article and finding no "empty pan" feature I went back to the title and read "chamber" not "pan" and then looked up the word "bedchamber" and found out it is a bedroom.

Well anyway if you have gotten this far, do you have any micro-controller projects to help the disability you would like to share ? Or disability projects that you would like to see.
thanks
