Stuck at home? Study music and electronics for free!

I actually got the bug a few months ago. I have zero experience with electronics and I'm not so young but I thought I'd start. AE modular is probably to thank/blame I liked the thought of one day tinkering to make some modules.

I released the first skill to acquire was math, and this was from basically no skill. I ordered various books. At first it was frustrating but it's been a few months and I'm really enjoying algebra, which surprises me because I'm definitely not a natural and always hated math. I have electronics books ready and have completed some of medium complex formulas once I understand what some of the variables mean. I don't feel that confident yet though. Most of it is still way beyond me.I'm not sure what level I'd need to reach in math just to do electronics. I guess that intermediate algebra skills and then being specific to the electronics formulas would save time in the long run.

I started looking into basic Arduino programming and it's not that bad. I downloaded some PDFs  to read and haven't been through them all yet, but there doesn't seem to be that many amazing  books about it in my opinion. There is a Youtube channel called Paul McWhorter and he makes it very easy to understand the basics. There are a few Arduino books based around musical projects.
