## Step 4: Remote control

|
|
We can use the radio on the @boardname@ to control the toy car remotely.
|
|
A second @boardname@ will send commands to control the throttle and the steering.
|
|
|
|
```blocks-ignore
|
|
let steering = 0
|
|
let throttle = 0
|
|
radio.onDataPacketReceived( ({ receivedString: name, receivedNumber: value }) => {
|
|
led.toggle(0, 0)
|
|
if (name == "throttle") {
|
|
if (value > 0) {
|
|
kitronik.motorOn(kitronik.Motors.Motor1, kitronik.MotorDirection.Reverse, 100);
|
|
} else if (value < 0) {
|
|
kitronik.motorOn(kitronik.Motors.Motor1, kitronik.MotorDirection.Forward, 100);
|
|
} else {
|
|
kitronik.motorOff(kitronik.Motors.Motor1);
|
|
}
|
|
} else if (name == "steering") {
|
|
if (value > 0) {
|
|
kitronik.motorOn(kitronik.Motors.Motor2, kitronik.MotorDirection.Forward, 100);
|
|
} else if (value < 0) {
|
|
kitronik.motorOn(kitronik.Motors.Motor2, kitronik.MotorDirection.Reverse, 100);
|
|
} else {
|
|
kitronik.motorOff(kitronik.Motors.Motor2);
|
|
}
|
|
}
|
|
})
|
|
basic.forever(() => {
|
|
throttle = 0
|
|
if (input.buttonIsPressed(Button.A)) {
|
|
throttle = 100
|
|
} else if (input.buttonIsPressed(Button.B)) {
|
|
throttle = -100
|
|
}
|
|
radio.sendValue("throttle", throttle)
|
|
steering = 0
|
|
if (input.acceleration(Dimension.X) < -512) {
|
|
steering = -100
|
|
} else if (input.acceleration(Dimension.X) > 512) {
|
|
steering = 100
|
|
}
|
|
radio.sendValue("steering", steering)
|
|
})
|
|
radio.setGroup(12)
