Example Code for UNIHIKER K10 - Digital input/output

Hardware Preparation

• UNIHIKER K10 * 1
• Multi Function Expansion Board for UNIHIKER * 1
• Gravity: Analog Rotation Potentiometer Sensor * 1 or other digital sensors
• Gravity: Digital Push Button * 1 or other digital sensors

Note: The multi-functional expansion board requires separate power supply when IN use. It can be powered by installing an 18650 battery or from the USB IN of the expansion board, and the PWR power supply switch needs to be turned on.

Software Preparation

#include "DFRobot_UnihikerExpansion.h"
DFRobot_UnihikerExpansion_I2C eunihiker(&Wire);
void setup()
{
	Serial.begin(115200);
	while(!eunihiker.begin()){
		Serial.println("NO Deivces !");
		delay(1000);
	} 
	Serial.println("Device connected !");
	eunihiker.setMode(eC0, eReadGpio);
	eunihiker.setMode(eC1, eWriteGpio);
}

void loop()
{
	if(eunihiker.getGpioState(eC0) == 1){
		eunihiker.setGpioState(eC1, eHIGH);
	}
	else{
		eunihiker.setGpioState(eC1, eLOW);
	}
}

UNIHIKER K10 Result

Light on when the button has been pushed down.
Light off when the button has been released.
