The supply voltage will vary from 12 -14 volts DC. I was going to use a 5 volt LM1117T with diode to drop it down 0.7 volts for approx 4.3 volts, OR I could use the LM1117T, 3.3 volts and no diode.... Is there any advantage or disadvantage to running at higher volts? The 3.3 volts is enough...

Basic help with PUSH BUTTON and counting memory. I'm new and have done coding long ago. I looked for threads on button pushing. I need basic help initializing the program and getting a basic counter to work with BUTTON PUSHING. Not sure if the "Button command" is useful for this, see below...

I have a simple program using input pins 1, 2, 3 and pins 0, 4 as output. When I do simulation it seems all the inputs are LO. The default position of them is Hi by design, unless signaled low. I selected the proper IC -08M and identified the inputs and two outputs. The Analogue Panel shows: A0...
