Design a circuit with three momentary, normally open, button inputs and one LED output. The LED must light anytime exactly two (2) of the buttons are pressed simultaneously. The LED has the following characteristics:
Vf = 0.83
If = 14.2
- Draw a neat schematic diagram for the entire circuit, including input buttons, logic , etc.
V = IR
The Attempt at a Solution
I know there are several ways of doing this but i am just not sure how to approach this. I was going to attempt to put the switches in parallel with pull up resistors to ground any voltage floating when the buttons arent pressed but as far as the logic i am not sure how to "attack" this problem. Thanks in advance
