# Servo Calibrator
|
|
|
|
Use this program to calibrate the angles of a servo.
|
|
Press ``A`` to reduce the angle by 5 and ``B`` to
|
|
increase it by 5.
|
|
|
|
The current angle is displayed on the screen
|
|
in a loop.
|
|
|
|
```blocks
|
|
let angle = 90
|
|
input.onButtonPressed(Button.A, () => {
|
|
angle = Math.max(0, angle - 5)
|
|
pins.servoWritePin(AnalogPin.P0, angle)
|
|
led.stopAnimation()
|
|
})
|
|
input.onButtonPressed(Button.B, () => {
|
|
angle = Math.min(180, angle + 5)
|
|
pins.servoWritePin(AnalogPin.P0, angle)
|
|
led.stopAnimation()
|
|
})
|
|
basic.forever(() => {
|
|
basic.showNumber(angle)
|
|
})
|
|
pins.servoWritePin(AnalogPin.P0, angle)
|
|
```
