#include <UltraSonicManage.h>

void setup() {

UltraSonicGesturer.Initial(cTrigPin, cEchoPin, &Process_WaveEvent);

}

void loop() {

UltraSonicGesturer.Check_WaveEvent();

}

//---------------------------------------------------------------------------------------------------

Step 3: Add your control code in Process_WaveEvent()

// Triggered if WaveEven ---------------------------------
void Process_WaveEvent(TUltraSonicGesturer*, TWaveState ws, int aCnt, float frDistCM, float toDistCM) {

switch (ws) {

case wsWaveIn: // Hand in 
// add your control code here......

break;

case wsWaveOut: // Hand

// add your control code here......

break;

case wsWave: // Hand in&Out
