Motor

spins continuously at power value

Servo

rotates between 0 and 100 degrees

digital sensor examples

Bumber switch and limit switch

Analog Sensor examples

potentiometer

Analog and Digital sensor examples

optical sensor and distance sensor

Potentiometer

-analog sensor

-rotates 0-265 degrees

-value range with max of 4095

distance sensor

-uses laser to measure distance of object in front

-detects an object and determine the relative size

-calculate a robot’s approach speed

range is 20mm-20,000mm

Brain

-21 smart ports

-8 3-wire ports

-stores 8 programs

Smart ports

-auto recognition of any v5 sensor

-auto recognition of any v5 motor

3-wire ports

-analog input: brain displays analog value

-digital input: brain displays digital value

-Digital out high” brain makes a “high” (1) signal to send to device

-digital out low: brain makes a “low” (0) signal to send to device

Digital sensor definition

specific, separate values usually represented as binary 0’s and 1’s

analog sensor

continuous and can take value within a range

“while” loop

allows section of code to repeat as long as condition is true

part of a “while” loop:

-”while”

-condition

-commands to repeat

Condition

controls how long/how many times “while” loop repeats

-condition is checked once every time loop repeats

commands

repeat while condition is true

Boolean logic

program decision based on questions

only two possible answers:

-yes/no

-true/false

Boolean statement

statement that can only be true or false

truth value

truth-or-false value

“if” statement

evaluated by condition in parentheses

-if condition is true, commands between braces run

-if condition is false, commands are ignored

-like “while” loop, but code won’t repeat

“if-else” statement

expansion on “if” statement

-”if” checks condition, runs appropriate command if true

-"else” allows code to run when condition is false

-”if” or “else” branch is always run once

Multiple “if-else” statements are dangerous because:

you may create a scenario where two statements “fight” one another
