So I have a great project in mind and I'm thinking about using the Raspberry Pi for circuitry fun. However, I'm not a computer whiz by any means (I do not understand programming, computer talk, etc.). I like working with integrated circuits and soldering circuits to make things work; so my question is, does the Raspberry Pi have simple positive/negative input/output function/components/connectors that are apart of the circuit board? If so, how many? How can I program these outputs?
