The LM2903 IC consists of two independent precision voltage comparators on the Click Board™ that operate over an extensive range of voltages. The comparators can operate from a single power supply as well as dual supplies.
When paired with analog sensors, the Comparator Click Board™ allows user to hook up an analog signal. The voltage from this analog signal is used as an input and compared with the physical value set as a reference by using the potentiometer. The device will then digitally check if your input voltage is higher or lower than the referenced value. If the input value exceeds, an interrupt signal is triggered.
The Comparator Click Board™ is designed to be used with single or dual power supply. For single power supply,

The Comparator Click Board™ communicates with the device via GPIO driver. This library contains drivers for check state of the OUT1 and OUT2 pin function.
The application is composed of three sections:
void applicationTask()
{
outStateOne = comparator_checkOutputOne();
outStateTwo = comparator_checkOutputTwo();
mikrobus_logWrite( " Output One : ", _LOG_TEXT );
if ( outStateOne )
mikrobus_logWrite( "High", _LOG_LINE );
else
mikrobus_logWrite( "Low", _LOG_LINE );
mikrobus_logWrite( " Output Two : ", _LOG_TEXT );
if ( outStateTwo )
mikrobus_logWrite( "High", _LOG_LINE );
else
mikrobus_logWrite( "Low", _LOG_LINE );
mikrobus_logWrite( "-------------------", _LOG_LINE );
Delay_1sec();
}

Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message
