Step counter
This project turns the @boardname@ into a simple step-counter. Each shake event increment a counter variable.
~ hint
If you built a watch in the make portion of the of the Watch project, you can use the code from this project with it too.

A counter
To build a counter, we will need a variable to store the number of steps.
let step = 0
step = 0
Detecting a step
Assuming you attach the @boardname@ to your foot, it will get shaken up when do a step. We can use the ||input:on shake|| event to detect a step (it should work most of the time). Let's add the code to increment step by 1 when @boardname@ is shaken.
let step = 0
input.onGesture(Gesture.Shake, function () {
step += 1
})
step = 0
How many steps so far?
We want to see the number of steps at all time. In a ||basic:forever|| loop,
we add a ||basic:show number|| block to display the value of step.
let step = 0
input.onGesture(Gesture.Shake, function () {
step += 1
})
basic.forever(function() {
basic.showNumber(step)
})
step = 0
Display lag
Did you notice there is a lag in the display of steps?
This is because the step value can change while the @boardname@ is displaying a number.
To remove the lag, add ||led:stop animation|| after changing the value of step.
let step = 0
input.onGesture(Gesture.Shake, function () {
step += 1
led.stopAnimation()
})
basic.forever(function() {
basic.showNumber(step)
})
step = 0
