Advice on my work


Hello all,
I am in an education field for last 4 years. Recently I came across a controller known as “BBC micro:bit”. I liked it a lot and started to learn to code it.
Now, I want to share my learning in form of YouTube videos.

I have made some videos which you can find from the link given below. But I want some advice to improve the overall quality of my videos.

The most critical issue for me is less budget.
I request you to guide me in my work. Thank you in advance…
