Connecting a Touch LED
Items you will need:
• Fully assembled VEX IQ Robot such as the Standard Drive Base, Autopilot Robot, Clawbot
or Clawbot with Sensors (See
installed in the Robot Brain
• VEX IQ Controller with Radio and Controller Battery Installed
• Touch LED (228-3010)
The Touch LED is an input device that responds to interaction from a person touching the top
dome. The top dome of the sensor can glow in up to 16 million different colors. Touch LEDs
are connected to the Robot Brain using Smart Cables. These cables come in assorted lengths
between 200mm and 600mm long. All sensors should be connected to the Robot Brain with
the power OFF. Smart Cables can only be plugged in one
way; when fully inserted they lock into place.
The default Driver Control program on the Robot Brain will
automatically look for and find the four advanced VEX IQ
sensors (Touch LED, Distance Sensor, Color Sensor, and
Gyro Sensor) on any unused port. Connect the Touch LED
to any unused Smart Port on the Robot Brain.
If there are multiple advanced sensors of the same type
plugged in (for example, two Gyro Sensors), the Driver
Control program will only respond to the sensor on the
lower port number. There are no restrictions to type or
quantity of sensor use when the Robot Brain is running a
custom user-created program.
The default Touch LED functionality in the Driver Control program is to act like a traffic light
for the robot. When the Touch LED glows green, the robot is free to drive. But when the
Touch LED glows red, the robot must stop. The Touch LED can be changed between green
and red by tapping the top dome of the Touch LED.
• Turn ON the Robot Brain and Controller.
• Select and run the Driver Control program.
• The robot starts in enabled mode with the Touch LED glowing green. Tap the top dome
of the Touch LED to change between enabled (glowing green) and disabled (glowing red)
mode.
• Try to drive when green
• Try to drive when red
