The “AND” function, a marvel of simplicity. Logic Circuits, 11/101 

If it was a coin, it was having the “OR” on one side, the “AND” being on the other.
Maybe the most straightforward function, the “AND” is than making pair with the “OR”.
The OR does logic addition, the AND performs the multiplication.
How do you translate that into practical understanding?
Simply by watching the app in the video.
All elements are safety oriented, on no less than 4 levels.
On the first level the two red push buttons, on the second, the simulated safety curtain and on the third, the Emergency Switch.
What’s amazing though, the two green push buttons are the most surprising 4th part of the safety operation, as you cannot start the motor, unless you press the Left PB AND the Right PB simultaneously!!!
Isn’t that cool?
Thanks for watching and CU next Tuesday!
