Code a micro:bit to Gradually Change Position
Every time a button is pressed on the micro:bit, the servo's position incrementally increases by 4 until it reaches a value of 100.

Gradually Change Position
00:10
Create a variable position to store a value, and then continuously set the Servo A position to its value. Every time the Button A is pressed, increment the variable by 4 units, and constrain it so that its value doesn't go over 100.
input.onButtonPressed(Button.A, function () {
position = Math.constrain(position + 4, 0, 100)
})
let position = 0
position = 0
basic.forever(function () {
sb.setServoPosition(sb.servo(SBServo.ServoA), position)
})
If using micro:bit for the first time, follow this setup.
