@yezzer good luck! Electronics is a lot of fun.
Invest in a good soldering iron, like a Hakko with a digital temperature display. I spent way too long with a $10 Radio Shack iron and it was the single largest source of my problems with soldering.
Also, you don't want to make a habit of breathing solder flux fumes. Set up a small fan.
@seanmcbeth already have a lot of kit, have a TS80P flashed with custom firmware which is so much better than the £10 ones I used previously.
I mainly use i2c and SPI with either breadboards or #pimoroni breakout garden, so don’t get into any circuit building. Like what even is a diode etc. I did do an electronics course ~25 years ago, but don’t remember much.
@britishtechguru I have no problems with the programming side, I've been doing it for decades 😬
building circuits is not something I've done much of though, like - when I'd need to use resistors, capacitors, diodes, what is a vbus, when to use vsys, etc
