		== Description ==

		The 8833 motor driver expansion board uses PH2.0 terminals and an 8833 motor driver chip driven by the two-channel H bridge whose the largest current can be up to be 1.5A. It also integrates an IR receiver, ultrasonic sensor ports, analog ports, line tracking interfaces and pin headers for BT wifi and servo drivers. <br>


		== Parameters ==

		* Voltage USB 5V，DC 6-9V
		* Current Max current is 3A，the real output is around 1A（2A, when the motor is loaded）
		* Max Power
		* Max power is 27W; in fact, it is 9W
		* Working Temperature: -10~50℃
		* Size: 695618mm
		* Weight: 25.5g
		* Environmental attributes: ROHS

		Test Code

		<pre>

		#define ML_Ctrl 4 //define control pins of the left motor
		#define ML_PWM 6 //define PWM control pins of the left motor
		#define MR_Ctrl 2 //define control pins of the right motor
		#define MR_PWM 5 //define PWM control pins of the right motor

		byte speeds_L = 200; //initial speed of the left motor is 200
		byte speeds_R = 200; //initial speed of the right motor is 200
		String speeds_l, speeds_r; //receive character strings of PWM，used to transfer into the PWM value

		void setup() {

		pinMode(ML_Ctrl, OUTPUT);
		pinMode(ML_PWM, OUTPUT);
		pinMode(MR_Ctrl, OUTPUT);
		pinMode(MR_PWM, OUTPUT);

		}


		void loop() {


		Car_front(); //go forward
		delay(2000);
		Car_back(); //go back
		delay(2000);
		Car_left(); //turn left
		delay(2000);
		Car_right(); //turn right
		delay(2000);
		Car_Stop(); //stop
		delay(2000);

		}


		/*************motor running************/
		void Car_back() {

		digitalWrite(MR_Ctrl, LOW);
		analogWrite(MR_PWM, speeds_R);
		digitalWrite(ML_Ctrl, LOW);
		analogWrite(ML_PWM, speeds_L);
		delay(10);
		}

		void Car_front() {

		digitalWrite(MR_Ctrl, HIGH);
		analogWrite(MR_PWM, 255 - speeds_R);
		digitalWrite(ML_Ctrl, HIGH);
		analogWrite(ML_PWM, 255 - speeds_L);
		delay(10);
		}

		void Car_left() {

		digitalWrite(MR_Ctrl, HIGH);
		analogWrite(MR_PWM, 255 - speeds_R);
		digitalWrite(ML_Ctrl, LOW);
		analogWrite(ML_PWM, speeds_L);
		delay(10);
		}

		void Car_right() {

		digitalWrite(MR_Ctrl, LOW);
		analogWrite(MR_PWM, speeds_R);
		digitalWrite(ML_Ctrl, HIGH);
		analogWrite(ML_PWM, 255 - speeds_L);
		delay(10);
		}

		void Car_Stop() {

		digitalWrite(MR_Ctrl, LOW);
		analogWrite(MR_PWM, 0);
		digitalWrite(ML_Ctrl, LOW);
		analogWrite(ML_PWM, 0);
		delay(10);
		}


		</pre>

		== Test Result ==

		The motor will rotate clockwise for 2s then anticlockwise for 2s, turn left for 2s, turn right for 2s and stop for 2s.
