Fuzzy logic using Arduino Uno

Using Arduino Programming Questions

The code below is still wrong when I press one of the buttons so the (out value) is not updated.

Please help me, when button one is pressed then (out1 value) is updated like when it loops, and when button two is pressed then (out value) is like when it loops, and when button three is pressed then (out1 value) and (out value) are updated like when loops.

buttons are typically connected between the pin and ground, the pin configured as INPUT_PULLUP to use the internal pullup resistor which pulls the pin HIGH and when pressed, the button pulls the pin LOW.

a button press can be recognized by detecting a change in state and becoming LOW and may need to be debounced (e.g. delay (20)

The condition is always false.

Perhaps you meant “||” instead of “&&”

This happens three times in your sketch
