I like to do the project based on MicroController with sensor.
My project is that if i will be standing in front of the door then the door would open automatically.
If anybody knows the LINKS about sensor , circuit and programs send me this is very helpful to me.
Take a look at the links section of the SensorForum group: **broken link removed**. You don't need to join the group of to hate a yahoo ID to see the links.
If you join the group though, there are some useful tutorials in the files section.
