Re: New Raspberry Pi 3 B+ won't boot

Why has it been deemed necessary or acceptable to resurrect this discussion and turn it into an argument?

The OP has reported that the original RPi has been accepted back on the premise that it was DoA, and the replacement is working satisfactorily.

Why does anything else need to be said...

Welcome to the Raspberry Pi forums. Isn't the point of a final project for you to demonstrate how you can apply what you have learnt? So what sensors could possibly detect and follow a human? IR? Reflected light? Gas emissions? A 'beacon' from a smartphone? Sound detection? It's your job to evaluate...

Welcome to the Raspberry Pi forums. What have you been asked to measure? Whether or not it is 'raining' - whatever that means - where you are, right now? Or how much rain has fallen over some past period? Or something else? Possibly the point of the project is for you to demonstrate what you can do ...

I still cannot control the light bulb (i.e. change brightness, change color). Are you able to command the bulb in any way at all? Do the On, Off and Toggle commands work?

Maybe you should seek advice from the manufacturer, as already suggested. With an internet search I found this for you.

all i need is for the screen to work

What does that mean?

It seems to be an HDMI display, so if you just connect it to the HDMI output port of your RPi do you get viewable output? Is that what you need?

One possible approach - no doubt there are many others - is to take advantage of the ability to publish and retrieve data provided by mqtt .

Is it possible that the tutorial you have followed is for an early 26-pin RPi? Might some of the pin assignments be inappropriate for a later 40-pin RPi such as your RPi3B?
