TETRIX PULSE Controller Sensor Port Pinout Diagrams
PULSE Sensor Ports
The PULSE controller uses Arduino UNO-compatible pin assignments. The sensors that are
supported in the PULSE Arduino Library are set up automatically using the library functions.
Support for different types of sensors will be added as they become available. However,
the ports are all directly accessible using Arduino coding functions if you wish to code with
additional sensors not yet supported in the PULSE library. With the exception of the I2C
port, all can be configured as inputs or outputs using the Arduino pinMode() function. To

Note: The PULSE I2C
port can be used
only in I2C mode. It
cannot be configured
for analog or digital
mode.
Note: Analog sensor
ports A1-A3 can also
be configured as
digital input/output.
