I recently got back into it. There are tons of youtube videos that provide tutorials. What helped me most was having concrete and doable projects that you'll want to finish. My first project was a digital dice (attiny85, 7 leds, CR2032, button and a small perfboard). Now it's a led strip for a camper (esp8266 w WLED firmware, potentiometer, 5V stepdown converter). I'm also toying with radio transmission over 433Mhz so I can have battery powered sensors (water-well depth, temperature, etc)
