Photos and Sensor Instructions VEX Testbed Photos and Sensor Instructions Finish your testbeds!

Finish your Testbed! Please open to page 23 in your packet. Use the VEX Testbed powerpoint on www.mrjopp.com to help you fill out the questions on pages 23-25.

Finish your Testbed! Please open to page 23 in your packet. When you are done, check over your testbed and make sure the wires are connected correctly.

VEX Testbed SENSORS MOTORS We will use the motors and sensors in your toolkit to build the testbed MOTORS

Sensor Arrangement To the right of the cortex, attach the limit switch, bump switch, and line tracker To the left of the cortex, attach the potentiometer and place any type of gear on the top

VEX Cortex All of our robotic systems are battery powered. The battery plugs in the end of the cortex next to the ON/OFF switch

VEX Cortex - Sensors The right side of the cortex has “MOTOR INPUTS” The left side of the cortex has digital and analog “SENSOR INPUTS”

VEX Cortex - Motors First let’s hook up a motor. You need to use a “MOTOR CONTROLLER” whenever you connect a motor to the cortex. (To convert 2 wires into 3)

Notice the Black wire plugs in next to the numbers VEX Cortex - Motors Use ports 2 or 3 for motor connections # 1 is for the CLAW! #2 is for the RIGHT motor #3 is for the LEFT motor Notice the Black wire plugs in next to the numbers

Motors The motors are used to turn any axle attached to it. They are able to move in both forward and reverse directions. You need to use MOTOR SCREWS to attach the motors to your build. Code for motors might look something like this:

VEX Cortex – Digital Sensors Digital Sensors include: Limit Switch (Port 1) Bump Switch (Port 2) LED lights (Next Slide)

VEX Cortex – Digital Sensors Digital Sensors include: Limit Switch (Port 1) Bump Switch (Port 2) LED lights (Port 12)

VEX Cortex – Analog Sensors Analog Sensors include: Line Tracker (Port 1) Potentiometer (Port 2)

Limit Switch – Digital Port 1 The limit Switch can be used to trigger an action when it is pressed. This can include: Start Stop Wait A code using the limit switch would look like:

Bump Switch – Digital Port 2 The bump Switch can be used to trigger an action when it is pressed. This can include: Start Stop Wait A code using the bump switch would look like:

LED (any color)– Digital Port 12 LED’s are lights! We have green, red, and yellow LED’s with our VEX kits You need to use another switch to trigger the LED’s and turn them on or off A code using the LED’s might look like:

Line Tracker– Analog Port 1 The line tracker can be used to sense light and dark. Use this sensor to trigger other actions, such as Start Stop Wait Turn on/off LED’s A code using the line tracker would look like:

Potentiometer– Analog Port 2 The Potentiometer can be used to sense movement in an arc. It does not move on its own, rather it needs to be connected to a motor. CAUTION: It is very sensitive, do NOT force it to move or the internal parts will break. A code using the Potentiometer would look like:
