Hello everyone, I'm relatively new to dabbling with electronic circuits, so I decided to build my own FM transmitter using a circuit I found on the internet. The schematic has been attached as an image file. However, there are a few things I'd like to clarify. What exactly does the 'ground' in the circuit represent? Am I supposed to physically attach a wire and stick it onto the ground? And also, since the circuit doesn't use a variable capacitor, how is the frequency adjusted? Lastly, the power source (1.5V) is connected through a single point on the circuit? I don't quite get this either. I thought the battery had to be connected on the positive and negative terminals? Quite simply, I don't understand how the battery will be wired to the circuit. I assume it has something to do with the grounding, I just don't know what. That's about it. Thanks for your time.
