I've just started this journey. I always wanted to get into electronics and robotics, but instead went the software route. I've picked up an Arduino and microbit over the years, but they sit collecting dust.

It may sound silly, but I asked Gemini to recommend a learning plan and it came up with a detailed plan along with time estimates in months. The first step is reading and going through all the exercises in Make Electronics (third edition) which is very hands on.
