Example Code for UNIHIKER K10 - Ultrasonic Sensor

Hardware Preparation

• UNIHIKER K10 * 1
• Multi Function Expansion Board for UNIHIKER * 1
• Fermion: URM37 Ultrasonic Distance Sensor * 1
• Jumper Wires 9" F/F (10 Pack) * 1

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.

Hardware Connection

Use UNIHIKER K10 & Mind+

Use UNIHIKER K10 & Arduino IDE

#include "unihiker_k10.h"
#include "DFRobot_UnihikerExpansion.h"

DFRobot_UnihikerExpansion_I2C eunihiker(&Wire) ;
UNIHIKER_K10 k10;
uint8_t screen_dir=2;

void setup() {
	k10.begin();
	while(!eunihiker.begin()){delay(1000);}
	k10.initScreen(screen_dir);
	k10.creatCanvas();
}
void loop() {
	k10.canvas->canvasText(eunihiker.getSr04Distance(), 1, 0x0000FF);
	k10.canvas->updateCanvas();
	delay(1000);
}
