Incrementally increase the brightness of an RGB LED.
Create a variable brightness to store a value and then continuously set the RGB LED A
brightness to its value. Every time Button A
is pressed, incrementally increase 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.
