Motion Activated Stairs

[@user-ys4op3ux1p]

That's a really creative idea, I like it! Two things to improve though: 'Laser' is an acronym and it's not spelled with a 'z'. You can refactor the redundant code by doing something like this: if(Val15 < 220){ //Check if it's nighttime digitalWrite(46, HIGH); //Turn on the lasers delay(2); int lights[14] = {32, 33, ect..}; int sensors[14] = {analogRead(A1), analogRead(A2), ect..}; //Read sensors after turning on the lasers for (int i=0; i

Good approach to this. I have done similar using individually addressable RGBW LED strips, IR instead of laser and only having all the sensors powered up if someone approaches the stairs. Once built there are so many cool things you can do with the code to get some pretty amazing effects. Would recommend this project to anyone interested in doing so.

Great video!!! The intro was hilarious. 2 suggestions for simplifying the wiring though: 1) Using serial/addressable LED strips will reduce the amount of wire used. 2) Tilting the LASER at a slight angle and using a small mirror on the opposite side of the step to reflect the beam back to the photo-resistor board, that will be on the same side of the stair as the laser, will help reduce wiring as well.

Your are a man after my own heart.

looks pretty cool! Nice job putting this all together! code recommendations: use better variable names, e.g. DayNightSensor instead of Val15. It makes the code easier to read and edit when you need to. Another thing you could do is #define Stair1LEDs 32, #define Stair2LEDs 33, etc. so that in the code controlling them, it looks like this: digitalWrite(Stair2LEDs, HIGH); instead of the more ambiguous digitalWrite(33, HIGH); This also makes it easier to change if you need to change what pin controls which stairs. You just change it once in the #define and then everywhere that it's used it updated.

Thank you for the tips! much appreciated!

[@Triad3DStudio]

Great project! Would you be able to build a ceiling fan "fidget spinner", you know like the one's with the lights on them that you're able to program with a saying or images on it?

[@BuildItnow]

Thank you!, yeah that sounds like a fun project.

[@jonahswain]

Yeah a POV ceiling fan would be sick

[@ARUN-bx2ic]

For what digital pin 47 is connected?

[@karthikperiyasamy2299]

Hi..I got new project as same in video..for 28 steps..for do this howmuch cost will come...and can u support us

[@taragoodwin5411]

10/10 knew you would use that song in the beginning

[@BuildItnow]

Just seemed too fitting to not use

[@kingdavid4463]

Best intro ever

[@theepicosityofpizza]

Damn that intro go hard

[@ilynd]

spooked me

[@BuildItnow]

y'all get spooked easy

[@zaddysquid9153]

Might be a good idea to write the if statements as a function that takes 3 args

[@konukuauleki]

I would like to do something similar but with flood lights around the house.

[@angelvaca9232]

amazing bro.. coul you share the instrucction and arduino code please

[@NickGreenDC]

Awesome project!!!! Have you experimented with Laser Time of Flight sensors (TOF)? Might be able to get rid of the light sensor on each step and simplify the overall project. However, they are much more expensive than the laser / light diode approach. Also have you considered using WS2812B LED strips - individually addressable LED's that are RGB and run off 5v. They can make for some really cool animations!

[@BuildItnow]

haven't heard of them but ill give them a google, sound promising, thanks!

[@NickGreenDC]

To be clear, there would still be a sensor on each step, just no need to have a transmitter AND receiver on each.

[@adityamanjrekartechguyproj5162]

motion activated stairs using ultrasonic sensor video please

[@bobmarley6970]

You could have easily put all of the if statements into one big if statement that checks for day or night.

[@miguelnogueira8180]

The code if fine but it could be heavily optimised

Nice project. Ever heard of loops and functions though? 😂

[@SSnoWHand]

Nice job!

[@connor6505]

This project looked like tons of fun! XD

[@tom-stein]

What are you studying?

[@BuildItnow]

im not, would like to study electrical engineering though

[@Allan_aka_RocKITEman]

@BuildItnow >>> Great video...👍

[@hyped5723]

For loop would play nice in here :)

[@chapp2012]

Might be easier on the eyes to have the lights fade on and off

[@BuildItnow]

Very true, im going to add that in future features

[@relaymatik5984]

Nice

[@narutoninjaleoloera5674]

It's funny cause I watched dis and I don't even have stairs

[@d4rp645]

why dont you just put down some stone pressure plates and some redstone lamps? xD

[@BuildItnow]

Hmmm hadn't thought of that. Will defiantly do that in the next version

[@chrisroland2738]

Cool

[@jishaanish3101]

First

[@BuildItnow]

Damn, missed it again
