Can i mine crypto on mobile?

Can i mine crypto on android? I already downloaded multiple apps that claim to mine bitcoin but most of them seem fishy and the reviews where full of people saying they cant withdraw etc. Is there actually any app that is legit? It doesn’t have to be bitcoin, it can be anything (for example a memecoin) aslong as i can transfer it into real money. Im 17 and my plan is to use the socklets of our school that are intended to load up tablets so that my smartphone mines some kind of crypto while i am in school and i don’t have to worry about energy costs. I think it wont be that much but for sure could get me like 20€/year, better than nothing and some coins may also skyrocket in prices.

I also have an arduino, do you think i could use that?
