the Dog
"Walk the Dog" is an exercise in direct control of the robot( vs autonomous control programs such as the line follower).
It also introduces another application of switches in a polling loop, in which the program serially 'polls' each switch.
Algorithm:
- Left Motor - B
- Right Motor- C
- Left switch- 1
- Right Switch- 2
Loop:
- If button 1 released, motor B goes forward indefinitely
- If button 1 pressed, motor B goes backward indefinitely
----------------------------------------------------
- If button 2 released, motor C goes forward indefinitely
- If button 2 pressed, motor C goes backward indefinitely
end of loop
Question:
Is direct, manual control easier and/or more accurate than autonomous control loops such as the line follower?
