Ask HN: Where did you learn modular electronics?
216 by BrandoElFollito | 65 comments on Hacker News.
I like to build simple IoT devices and code around them. While I am comfortable with the dev part, I have problems to understand the electronics. This is why I started with modules (arduino, nodemcu, sensors, audio amplificators) but there are issues the weird resistor, capacitor and whatnot which is plugged beyween, say, the arduino and the sensor. Is there a place I could learn this "modular" electronics, where I could find "cookbook" advices on these elements needed for the modules to work correctly? Since this is the way I lend to develop (take a problem, look at the solution and understand the details on the go) I would love to get into electronics via this path, if possible.
