Hey everyone, amateur electronics hobbyist here. I've just got a simple question about the schematic on the site. There appear to be 3 ICs referenced in the schematic, however the parts list only contains 2. The particular IC I'm confused about is pictured here:
It's got no part number, but it is labeled as IC2. I don't know what it could be and I don't want to just ignore it and find out I was in fact missing something. I'm still in the process of building this circuit (without the PCB, I'm just using a breadboard) so I figured I might as well ask before I finish it just in case.
Thanks for reading :D Since this is my first post, have a cat in a box.
