[vc_row][vc_column width=”1/1″][vc_column_text]Linker Touch Sensor is a touch switch, when a finger touching the sensing area, SIG (signal output) in the Linker Touch Sensor will output a high level (logic 1), when there is no touch SIG will continue to output low (logic 0). Then pcDuino can judge the state of the switch by detection Touch Sensor SIG level through GPIO. Let us control the linker led by Touch Sensor.
