Jolly good. But, it's a bit of an ambitious project if you are just starting.Yes, I am Electrician.
I would like to make software to control MOSFETs in case to keep the current in phase with voltage and also to be sinusoidal.
So don't worry about keep me alive
Anyway, to answer your questions:
First, a shop- you'll have to say what country you are in. Better if you can say what region, or your nearest city, then you might get local advice. It might be easier to order online and get stuff delivered.
Second, an ADC- the Pico has a built-in ADC. Do you really need an external one?
Third, a book - the Pico is a relatively new micro. Probably there are few books available, and it might be too early for any particular one to stand out. It also depends on which language you want to use.
I sampled the current in a 3-phase 240Vac 50Hz solar inverter using an Arduino and current transformers. The current transformers generated a proportional voltage. I offset the voltage to 2.5V and fed it to three of the ADC inputs and sampled them regularly. I can't really remember the details, but once I had the ADC readings I applied some simple maths and logged the results to an SD card. This was a cheap hack to acquire data to decide what to do next with the inverter.
