We never stop working to be impressed by the ingenuity as well as skills of wise house hackers as well as we’ve been complying with Robert Hekkers’ Staircase illumination job because last September.
Now the job is completed as well as the 12 LED strips, IR light barriers, 16-channel LED driver, as well as Arduino / Raspberry Pi controls are all in place. Check out the video below for some incredible automated LED stairway illumination action…
So exactly how does this contraption work? The Raspberry Pi that’s near the Arduino runs a Node.JS script. This script essentially controls the ‘state’ in which the Arduino is. With the serialport module this Node script can send commands to the Arduino like ‘reset’, ‘on’, ‘off’, ‘day’, ‘night’, ‘demo’, ‘stop’.
The reset command triggers a ‘reboot’ of the Arduino by jumping to address 0. The on/off commands are utilized to tell the Arduino whether it ought to act on the light barriers being damaged or not, day as well as night tell the Arduino whether it’s day or night in our world (which has it’s impact on the brightness of the LED strips), as well as the demo command… well, you can do incredible stuff with 13 private LED strips!
