Code stops here if don’t open the serial monitor, so open serial monitor.
LIS.begin(WIRE);
LIS.setOutputDataRate(LIS3DHTR_DATARATE_50HZ);
Description: Initialize the accelerator.
Syntax:
LIS.begin(Wire) .
Description: Sets the output data rate of the accelerator.
Syntax:
LIS.setOutputDataRate(odr_type_t odr) .
Initialize the accelerator and set the output rate to 50Hz.
