when i came back from the us, i brought back with me an arduino kit. i had some arduino experience from a class i took but it was all on tinkercad and that was pretty much it. so i started off with a goal and the plan is to build small stuff that build to that main goal.

so what's this main goal?

it's simple really, i want to automate as many stuff as i can in my life, so i'm thinking automating my garden, all the lights at home, the gate and probably feeding my cat.

stage 1: lights

so this post is going to be about stage 1, where i deal with my lights. so what i did was i made an automatic light switch when i open my door (which just so happens to be an event that takes place when im leaving or entering my room).

i wasn't sure what i wanted to use as a sensor but at the end i stuck to the ultrasonic sensor since i felt like that was just gonna work better tho in the future i probably might try out doing it with motion sensors placed around my room.

so i started off by connecting the ultrasonic sensor to the arduino and then connecting the arduino to a servo motor which basically presses the light switch. later on i'm going to make it in such a way that doesn't need like an external actuator and stuff, like everything happens inside the light switch case and theres a relay that does all that instead.

so then i worked on the code which was lightwork and it wasn't anything too complex or overwhelming :)

i havent recorded any samples of it working since its still in the works but i'm currently working on casing it so it doesn't look so unappealling lol

i also want to build alexa support from scratch in the future when i get a hue bulb.

the github repo is here if you wanna check it out :)

enough yappery from me, see y'all next post, byee!
