My first Arduino project (using an ATMega 328) is triggered by a roughly 5V to 0V edge and works fine overall. (It sends a series of servo arm movements.) But I'm still playing with various simple front end circuits to deliver that edge.
I'd like to use Spice simulation to experiment with these, as I do frequently with other electronics projects. What would be the simplest way to represent one of the digital input pins please, say Arduino D7? I’m hoping it can be done with a few simple familiar components.
