3-Wire Devices

3-Wire devices connect to the three-pin ports on the V5 Brain. These devices include sensors, motors, and actuators that communicate using simple analog or digital signals.

Below is a list of available 3-Wire devices:

• Accelerometer – Detects acceleration and tilt along multiple axes to measure motion and orientation. The sensor includes a jumper that adjusts sensitivity between 2G and 6G ranges.

• Bumper Switch – A spring-loaded switch used for detecting collisions or impacts on the robot.

• Digital In – Reads binary input signals (HIGH or LOW) from external devices such as switches or sensors.

• Digital Out – Sends binary output signals (HIGH or LOW) to control external devices like LEDs or relays.

• Encoder – Measures the relative rotational position and direction of a shaft to determine speed or distance traveled.

• Gyro Sensor – Measures the rate of rotation of the robot to track turns and maintain heading orientation.

• LED Indicator – Controls LED Indicators by turning them on or off.

• Light Sensor – Measures the intensity of ambient light to detect brightness or contrast changes in the robot’s environment.

• Limit Switch – A small switch that detects contact with objects or surfaces.

• Line Tracker – Detects differences in light reflection, allowing the robot to follow lines on the field surface.

• Motor 393 – A legacy DC motor from VEX EDR systems.

• Potentiometer – Measures the angular position of a rotating shaft or mechanism. The sensor supports 270 degrees of rotation.

• Range Finder – Uses ultrasonic sound waves to measure the distance between the sensor and nearby objects.

• Servo Motor – A position-controlled motor used to rotate mechanisms to specific angles.
