Ok. to start again. To start with no mercury switches may be used. I am looking to build a box device that has these features:1.. one switch for turning it on and off 2.. one led to light up when armed 3.. the ability to be armed when placed at any angle without being adjusted in anyway 4.. To sound an alarm upon being moved 5.. the ability to run off a 9V battery
These are the conditions for the device. So far a two axis Accelerometer seems to be the best way to sense the movement of the device. Any ideas?
