Solutions
Q1. A tactile switch.
Q2. Zero (0) volts, resulting in Binary zero (0) at the input register.
Q3. IN7 = 1 means the right whisker is not pressed.
Q4. The
Q5. The program can check for one condition, and if that condition is true, it can
E1. The key to solving this problem is to use a second
E2.
IN8 = 0 when whisker is pressed. IN8 = 1 when whisker is not pressed.
IN7 = 0 means the right whisker is pressed.
IN5 = 1 means the left whisker is not pressed.
IN5 = 0 means the left whisker is pressed.
to decide which subroutine to jump to. That decision is based on conditions,
which are logical statements that evaluate to true or false.
check for another condition within the first condition.
