Motion Sensor randomized Visual Output Device
Hello! :)
I'm new to this forum and looking for some help with a project I'm working on.
The device I need to construct should have the following features:
1. A Motion sensor that detects anyone stepping on an area of about 15x15 inches.
2. Transmits signal wireless to a device up to 20 feet away
3. That device randomly selects a visual signal like a light coming on. There should be a way for a person using the device to choose between the number of lights that can come on. One out of two, one out of three, or one out of four. The time between the motion sensor being activated and the visual signal going off should be minimal.
To make it more clear:
There would be four lights. The user of the device could choose three Options:
1.) light 1 or 2 comes on (random selection which one)
2.) light 1, 2, or 3 comes on (random)
3.) light 1,2,3, or 4 comes on (random)
How difficult and expensive would it be approximately to build this device?
Where would I look for the needed parts?
I'd really appreciate any advice anyone give me!
Thanks in advance!
