Replaced the relays for motor control with an L298N and made the entire thing run on 12v instead of 5v, sounds a bit more less feasable but it is actually more feasable because if ur using 5v usb , u need a power brick with good ampere ratings, 12v u just need a normal 12v barrel jack thingy
heatshrinking ! 
Made an interface, with a lot of help from ai, will rebuild this from scratch tomorrow, just made this using ai as a test, and the ui runs completely on ur pc as an html, it works although it is buggy and the sliders do do their jobs properly that much
heatshrinked some wires, didnt have time for anyhthing else lol
Installed node-red and mqtt broker
wired up the signal side of the relay #3
made it workkkk
cut some wood and added brackets to mount to the wall
tried arduino cloud iot, it sucks, so i will prob just make my own esp32 hosted webpage for the controls
messed around with esp rain maker even more, prob will not use it and just continue with arduino iot cloud or smthgn (image not related and not mine,jst a meme 
)
today was kinda boring, i just got esp rainmaker working, it took 1 hour because the esp32 storage and cache stuff, i had to create my own partition scheme and stuff to get the code to fit on the esp32 
installed a relay for ac stuff on another wooden block
cut and epoxied a peice of wood so i can install a relay for AC connections
Soldered on some male headers for the rgb led board
coded blynk then decided to not use it bc of its limitations
Made a curtian opener and closer thingy, the big metal thing is a motor ink assembly thingy i pulled from an old hp printer and i used relays instead of a l298n or tbh any motor driver bc … i only have the l298n and it is very inneficeint 
SOLDERED SOME STUFF
