Can I put small projects on github?

I am just practising small apps like binary2dec converter etc from https://github.com/florinpop17/app-ideas , So can I put whatever I accomplish on GitHub, even very small works? How can it impact when an employer sees a bunch of very small works on my repo? Will it have any positive impact? Though I will be showing only my best works through my portfolio.
