Hello everyone,
now that I am on my summer break from school I thought I start a little project that keeps me interested in the school material
What I would like to build:
Ok so I would like to build a lighting system for my stairs. I was thinking about 1 LED on the side of each step, which should be sufficient to see where your walking when its dark. I would like to trigger the circuit with a sensor that recognizes that I'm going up or down the stairs. Lastly I would like the lights to turn on one after the other, with a little delay, in the direction I'm coming from.
So if I walk down the stairs I would put the sensor on the top step and when I cross it I would see the lights turn on one after each other all the way down. When I go up then they should turn on from bottom to top.
After that they should turn off the same way, either after a certain amount of time, or when the second sensor is passed.
Alright this is what I had in mind. I haven't done any designs so far and wanted to check here what you guys think about the idea. I'm only one year into my electronics program at school so far and therefore still a bit limited but I thought this would be something I could be able to build over the summer.
From the things I know rights now, I know the effect I would like to achieve with the lights turning on after each other can be accomplished with a shift register, but would it also be an efficient way? I mean I am aiming for about 12-15 steps and with a shift register I would need that many bits.
Another thing is how to connect that circuit to the normal power in my house, because I obviously don't to run it on batteries
I guess I would need to build a power supply and also a circuit to generate a clock.
This is what I thought about so far. I would really appreciate if you could tell me if I'm on the right track or if I should design it completely different than that.
Thank you,
