Motion sensitive, LED flicker circuit?
I am working on a project with a friend which is basically a backlit sign, it will be lit with a 4-5 meter LED strip which runs on 12v. But will be mains powered. (just the LEDs are 12v)
I am looking to achieve an effect whereby the sign has a passer by and is disrupted, flickers (randomly) for just a few seconds but then returns to a solid light when there is no or less movement/change in light.
I am open to all kinds of suggestions and have some flexibility within the project to allow for extra components.
At the moment I do not have any components, I may however have access to a raspberry pi or something similar!
I hope someone can help!
If successful I will be sure to incooperate this and the help in to my very own instructable for the initial project.
Thanks in advance!
