I'm working with an instructor at the local community college to fix a bug in my first project, but he asked me to give him a schematic to look over before we meet in person. I know what resistors and the other simple stuff looks like, but I don't know the symbol for ICs and VRs. Since the symbol for ICs are dependent to each individual IC, do I just draw a box and label the pins I'm using? That seems the most intuitive, to me. I have no idea what to do for the VR. Can someone upload a pic or something? It would be immensely appreciated.
