Thanks for your replies!
INTP:
So, what are your ideas? What components do you have access to? Do you plan on using a whole Arduino just to turn on a lamp?
The lamp will have an arduino nano and a bluetooth board... Its one of the requirements that proffesors have determined (its a project for the university, Im studyng industrial design). So we have part of the hardware already there.
larryd:
Switches work well.
Indeed. But it would break the conept we are trying to achive. We are looking for something more minimalistic and "magicness". We have considered puting a normal switch behind a plastic housing, though. We call that the plan B (The lamp its kind of an "O" made of concrete, with a base at the bottom made of thermoformed plastic. Its a Technology class project).
mikb55:
What's your budget? The VL53L0x and VL6180X reflective time of flight sensors aren't cheap by hobby standards, but they'll do the job.
Mmm yeah, that would be to expensive, at least where I live (Argentina).
-> So IR LED + IR break-beam sensor OR capacitive sensor: This would be the options, right? I have access to that kinda stuff in the local stores. Any other suggestion or recomendations? I realice now that there was important info missing in my first post
Ill definitely have to show you the final result when its done, you are being very helpfull!
