Grove Zero

A Microsoft MakeCode package for for Seeed Studio Grove Zero module.

Basic usage

Sound

Show sad icon when the sound sensor detects a loud sound.

sensor.onLoudSound(() => {
    basic.showIcon(IconNames.Sad);
})

Get sound value and display on led matrix.

let sound = 0;
basic.forever(() => {
    sound = sensor.getSoundLevel();
    basic.showNumber(sound);
})

Use ||setSoundThresold|| to set the sound threshold.

Use ||wasLoudSoundTriggered|| to see if the sound sensor detected a loud sound.

Gesture

Show text on when the gesture sensor detects a motion.

sensor.onGesture(GestureEvent.Up, () => {
    basic.showString("up")
})
sensor.onGesture(GestureEvent.Down, () => {
    basic.showString("down")
})

Use ||wasGestureTriggered|| to see if the gesture sensor detected a specific gesture.

Encoder

Show text on when the knob is rotated or pressed.

sensor.onKnob(KnobEvent.Clockwise, () => {
    basic.showString("+");
})
sensor.onKnob(KnobEvent.Anticlockwise, () => {
    basic.showString("-");
})
sensor.onKnob(KnobEvent.Press, () => {
    basic.showString("*");
})

Use ||wasKnobTriggered|| to see if the knob was rotated or pressed.

Color

Show text on when the color sensor detects a specific color.

sensor.onColor(ColorEvent.R, () => {
    basic.showString("red")
})
sensor.onColor(ColorEvent.G, () => {
    basic.showString("green")
})
sensor.onColor(ColorEvent.B, () => {
    basic.showString("blue")
})

Use ||getColor|| to get the color value from the color sensor in R:G:B.

Use ||wasColorTriggered|| to see if the color sensor detected a specific color.

Liner

Show text on when the line follower recognized the position of the line underneath.

sensor.onLinePosition(LinerEvent.Left, () => {
    basic.showString("left")
})
sensor.onLinePosition(LinerEvent.Middle, () => {
    basic.showString("middle")
})
sensor.onLinePosition(LinerEvent.Right, () => {
    basic.showString("right")
})

Use ||wasLinePositionTriggered|| to see if the line follower recognized the position of the line underneath.

Servo

Set the servo to 90 degree

motor.moveServoTo(90);

Wheel

Run the wheel.

basic.forever(() => {
    motor.setMotormoduleAction(DirectionTpye.Forward, SpeedTpye.Fast);
    basic.pause(2000);
    motor.setMotormoduleAction(DirectionTpye.Backward, SpeedTpye.Fast);
    basic.pause(2000);
    motor.stopMotormodule();
    basic.pause(2000);
})

Use ||setMotormoduleSpeed|| to set the speed of motors on motor module.

Use ||whenMotormoduleLostLine|| to set the actions and the moving speed of motor module when it lost the line(detected by the line follower).
