4、Car turn left  tinybit.car_left(a)

Function: Control the car turn left

Parameter:

a is the speed of right motor of the car, range: 0 ~ 255

!Note: car turn left is left wheel stop and right wheel advance,so we only input right speed.

Eg: tinybit.car_left(255)  // The car will turn left with 255 speed

5、Car turn right  tinybit.car_right(a)

Function: Control the car turn right

Parameter:

a is the speed of left motor of the car, range: 0 ~ 255

!Note: car turn left is right wheel stop and left wheel advance,so we only input left speed.

Eg: tinybit.car_right(255)  // The car will turn right with 255 speed

6、Car spin left  

method1:  tinybit.car_spinleft(s)

method2:  tinybit.car_spinleft(a,b)

Function: Control the car spin left

One parameter:

A single parameter s is the speed of the two motors of the car, range: 0 ~ 255

Two parameters: 

a is left motor speed,range is 0-255.

b is right motor speed,range is 0-255.

Eg1: tinybit.car_spinleft(255)  // The car will spin left with 255 speed

Eg2: tinybit.car_spinleft(255, 255)  //The car will spin right with 255 speed

7、Car spin right  

method1:  tinybit.car_spinright(s)

method2:  tinybit.car_spinright(a,b)

Function: Control the car spin right

One parameter:

A single parameter s is the speed of the two motors of the car, range: 0 ~ 255

Two parameters: 

a is left motor speed,range is 0-255.

b is right motor speed,range is 0-255.

Eg1: tinybit.car_spinright(255)  // The car will spin right with 255 speed

Eg2: tinybit.car_spinright(255, 255)  //The car will spin right with 255 speed

8、Car stop  tinybit.car_stop()

Function: Control the car stop

9、RGB search light   tinybit.setMotorPWM(a, b, c)

Function: Set motor PWM value

Parameters:

a: the left motor speed (-255 ~ 255), positive number is forward, negative number is backward, zero is stop

b: the right motor speed (-255 ~ 255), positive number is forward, negative number is backward, zero is stop

c: delay time (ms)

Eg: tinybit.car_setMotorPWM(255, -255, 1000)  //Left motor rotates forward, right motor rotates reverse 1000ms with 255 speed.

10、Ultrasonic module return distance  tinybit.ultrasonic()

Function: returns the current distance detected by the ultrasonic module(cm).

11、Left tracking sensor  tinybit.traking_sensor_L()

Return value: if black lines are detected returns true, if white lines are detected return false.

12、Right tracking sensor   tinybit.traking_sensor_R()

Return value: if black lines are detected returns true, if white lines are detected return false.

13、Voice sensor   tinybit.getVoicedata()

Function: Get the value of the sound sensor

14、IR control   tinybit.init_IR(a)

Function: Initialize infrared remote receiver

Parameter:

a is pin of the infrared receiver

!Note: For building:bit, we need to select pin8

Eg: tinybit.init_IR(pin8)

15、Return button value of IR controller  tinybit.get_IR(IR_pin)

Parameter:

a is pin of the infrared receiver

!Note: For building:bit, we need to select pin8

Eg: tinybit.get_IR(pin8)

16、Input this code to import Yahboom Tiny:bit Micropython library：import ghandle

ghandle.B1_is_pressed()

Function: Key B1 (red), press to return to True, release to return to False

ghandle.B2_is_pressed()

Function: Key B2 (green), press to return to True, release to return to False

ghandle.B3_is_pressed()

Function: Key B3 (blue), press to return to True, release to return to False

ghandle.B4_is_pressed()

Function: Key B4 (yellow), press to return to True, release to return to False

ghandle.rocker(state)

Function: Detect the joystick direction, if it is consistent with the parameter return True , if it is inconsistent with the parameter return False

Parameters: state indicates the status of the rocker

ghandle.up --- rocker up

ghandle.down --- rocker down

ghandle.left --- rocker left

ghandle.right --- rocker right 

ghandle.pressed --- rocker be pressed

ghandle.noState --- no any operation

ghandle.get_value_x()

Function: Returns the analog value of the X channel of the rocker. The value will change when moving left and right. It increases to the left and decreases to the right.

ghandle.get_value_y()

Function: Returns the analog value of the Y channel of the rocker. The value will change when moving up and down. It increases to the down and decreases to the up.
