the line follower robot
TRANSCRIPT
REQUIREMENTS FOR A LINE FOLLOWER
The robot must be capable of following a line.
It should be capable of taking turns.
The robot must be insensitive to environmental factors such as lighting and noise.
It must allow calibration of the line’s darkness threshold.
The color of the line must not be a factor as long as it is darker or brighter than the surroundings.
The output from the IR Sensors module is analog.The analog voltage can be Converted to digital (0 & 1) by :
•ANALOG TO DIGITAL CONVERTERS (ADC)
•COMPARATORS
