		'''Description'''

		This pump driving module uses a single-channel H-bridge driver chip-HR1124S.
		The H-bridge driving part of HR1124S uses low on-resistance PMOS and NMOS power tubes, which can reduce chip’s power consumption and make the chip work safely for a longer time. In addition, HR1124S has low standby current and low quiescent operating current.


		'''Parameters'''

		Control chip: HR1124S
		Rated voltage: 1.8V-6.8V
		Rated current: low standby current (0.01uA) and low quiescent working current (0.2mA), continuous output current 1.2A.
		Product size: 31.6mmx23.7mm
		Operating temperature range: 1°C ~ 50°C

		== Control Logic ==

		Input and output logic table




		PWM can regulate the speed of the motor, for example, in clockwise, INA is high level and INB is low level, the rotation speed is the fastest.

		If INA inputs PWM wave, and INB also maintains low level; the duty cycle of INA is the speed regulation ratio.

		If INA keeps high levels and INB inputs PWM wave; the duty cycle of INB is the speed regulation ratio.

		== '''Test Code''' ==

		6.1 Test Code 1：（high and low levels output control）

		<pre>
		//*****************************************************************************
		void setup(){
		pinMode(5, OUTPUT);//Set digital 5 to Output
		pinMode(6, OUTPUT);//Set digital 6 to Output
		}

		void loop(){
		//make the motor rotate clockwise for 3000ms
		digitalWrite(5,LOW);//set digital 5 to low level
		digitalWrite(6,HIGH);//set digital 5 to high level
		delay(3000);//delay in 3s
		//make motor stop rotating for 1000ms
		digitalWrite(5,LOW);
		digitalWrite(6,LOW);
		delay(1000);
		//make the motor rotate anticlockwise for 3000ms
		digitalWrite(5,HIGH);
		digitalWrite(6,LOW);
		delay(3000);
		//make motor stop rotating for 1000ms
		digitalWrite(5,LOW);
		digitalWrite(6,LOW);
		delay(1000);
		}
		//*****************************************************************************


		6.2 Test Code 2：（PWM output control）
		//*****************************************************************************
		void setup(){
		pinMode(5, OUTPUT); //Set digital 5 to Output
		pinMode(6, OUTPUT); //set digital 6 to OUTPUT}

		void loop(){
		//make the motor rotate clockwise for 3000ms
		analogWrite(5,0); //set PWM value at digital 5 to 0
		analogWrite(6,200); //set PWM value at digital 6 to 200
		delay(3000); //delay in 3s
		//make motor stop rotating for 1000ms
		analogWrite(5,0);
		analogWrite(6,0);
		delay(1000);
		//make the motor rotate anticlockwise for 3000ms
		analogWrite(5,200);
		analogWrite(6,0);
		delay(3000);
		//make the motor stop rotating for 1000ms
		analogWrite(5,0);
		analogWrite(6,0);
		delay(1000);
		}
		//*****************************************************************************

		</pre>


		== Test Result ==

		Upload code, wire up and plug in the external power. The motor rotates for 3s clockwise, stops for 1s, anticlockwise for 3s and stops for 1s, circularly.
