I have a number of projects I'd like to undertake involving microcontrollers. The problem is that my hardware training was as a tech over 20 years ago, so no training in circuit design. The logic is easy enough it's just when when I look at schematics for various circuits there are a bunch of resistors and capacitors there and I don't know what they are for.
Anyway what I need is a book about circuit design that will enable me to figure out when I should but them in my circuits and what values to use.
Can somebody recommend one?
