Ok, So this has been done before, i know. There are even a few instructables already on how to make stair lights. Mine are a bit different. You see, I’m starting off on a ‘Home Automation spree’ and this is one of the elements in my house. This enables web/network based control over the stairs. All you need to do is ‘publish’ the settings and the Arduino will act accordingly. I do this through a PHP/JavaScript web page that utilises TCP socket communication. That’s a little outside of the scope of this instructable though.
The basic technology being used here is an Ethernet enabled Arduino and the MQTT protocol.
You will need:
– An Ethernet enabled Arduino (Preferably the WIZnet type, I have not tested this with others)
– 16 X Led strip lights or other lights you might want to use. I got mine from AliExpress for ~$2.50 each.
– 2 X 74HC595 Shift registers
– 2 X ULN2803 Darlington transistor Arrays
– 2 X 100nf Ceramic Capacitors
– 1 X 100uf 16v Polarised cap
Here is a demonstration movie.
