Need help for a project? Answered

So I've to make a multi-functional garbage container, which would be solar powered, and it must have an arduino . The idea is that the container will have 2 LCD displays showing a moving eye, a sensor for when something is thrown inside (the sensor must activate an audio device, which should say "thank you" at the moment) another sensor fr when the container is full (it'll have to make an LED blink) . So my knowledge about arduino is fair (about coding) and I wold need help for that and also for what components to use (mainly what sensor as I described)
All those things are gonna be made for a project and our budget is about 150$
Thanks in advance!

Make a list of the hardware you think your going to need. If you have some Arduino experience then this shouldn't be difficult.

Once you have thet you have a good idea of what the arduino is going to have to do and perhaps you can ask for some more specific help then.

I am going to need a total of 7 main components:
The arduino
2x LCD displays
Sensor #1
Sensor #2
Music player of some kind, to be triggered by the sensor
and at this point I don't know what sensors to chose
I'm more for like the IR sensor but don't know if they're gonna do the job

Your sensors will be an issue - garbage sensors as such don't exist. I would suggest you look at load cells to weigh the bins.

You could rig the bin on light springs and arrange levers to operate a sliding potentiometer read that with an analogue input and then you can see how heavy the bin is getting.

A microswitch under then that gets pressed when it reaches the bottom will indicate it is full (of course depends on the weight of the trash.

Any light based sensor is going to get dirty and cause issues.

Any cheap MP3 player you can take to pieces will work all you need to do is trigger the switches from the Arduino (somehow)

Two more items to your list... What size solar collector and battery will you need to work the Arduino, LCDisplays, sensors and music player to work in winter ??

Ask your teacher for more info and do your own research.
Homework and projects are for you to learn and not for others to do the learning for you ;)
