Controlling an automotive relay and a pulled up signal with one switch
I am trying to control an automotive relay and a pulled up signal.
When I press the push-button switch, I need to trigger the relay and ground the signal on a microcontroller pin. … When I simulate the circuit design, the voltage on node3 for triggering the relay is 9.949V. I need to get it to 12V. How can I do it?
