This is probably such a noob question but I really could not find the answer anywhere else. I'm trying to build a project that came with instructions but I'm a beginner.
It would be awesome if someone could explain what JP1, JP2 stands for in the attachment I provided.
Hi math83,
JP stands for JUMPER! or sometimes an HEADER, these are sets of Male PINS (Square in profile) or female sockets. Headers are usually used to connect ribbon or similar cables to a board (The Arduino UNO has female headers, the NANO has Male). A Male Jumper is often used to connect or disconnect a signal or power, this usually has 2 or 3 pins, you use a shorting block (for want of a better word) to make the connection, without the block the circuit is open. The 3 pin option gives you the choice of sending the signal in 2 different directions, etc. Also useful for connecting sensors to Arduino..
