I've wired a few very simple things but I'm expanding my horizons and working on a new project. Router with Analog meter
My instructions tell me to take the 3 volts coming from the router led and invert the signal before using a 741 op-amp to increase it. I don't really understand how the 74hc04 chip works. To invert the signal I would need to wire the gates back to back according to the instructions, but that doesn't make any sense to me. The 74hc04 chip has 6 gates and a Vcc and ground. Here are my questions:
1. Does the 3v + from led connect to the Vcc on the chip or do I need external power to power the 74hc04 chip?
2. How do you wire gates back to back?
Thanks,
Sander
