Magnetic Force
Find the amount of magnetic force (the strength of a magnet) in the direction you say.
input.magneticForce(Dimension.X);
~hint
The micro:bit measures magnetic force with microteslas.
~
Parameters
- a string that says which direction the micro:bit should measure magnetic force in: either
x(the left-right direction),y(the forward/backward direction), orz(the up/down direction)
Returns
- a number of microteslas that means the strength of the magnet
Example: metal detector
This program makes the center LED of the micro:bit get brighter when the magnetic force is stronger, and dimmer when it is weaker.
led.plot(2, 2)
basic.forever(() => {
let f = input.magneticForce("x")
led.setBrightness(f / 2000)
})
