When you set variable in blocks, then click show Code... the variable is automatically set as null

let item = null;
item = 0;

go to either of these browsers: firefox or IE

1. IE. 11.0.9600.38204
2. FireFox

3 go to codemicrobit.com/latest

1. drawers/tabs are removed, users only sees first 4 drawers on the block editor

with maker activities, students receive a finished program to run on the micro:bit after completing the maker activity

http://localhost:3232/lessons/ornament-chain/activity

http://localhost:3232/lessons/the-watch/activity

here is an example of the issue

0 go to my docs. page not rendering the blocks

http://localhost:3232/lessons/night-light/quiz-answers

1 go to KSF, JS

2 enter this code

led.setBrightness(128)
led.plotAll()

led.setBrightness(255)
led.plotAll()

there is no difference in brightness

Go to script...

https://codemicrobit.com/fkayhbkytt

Go to Project Settings - YouTube video inserted

https://youtu.be/TCAlAKvMx2M?list=PLE8XLCpSej07SC0CKPLsfhKNVelPXjBS4

The video is not noticeable. Does this feature work?

firefox browser issues - deleting blocks

repro go to this version of firefox

1. open ksf, blocks.

2 add these blocks

3 expect to be able to delete these blocks, they are stuck in the drawers

importing not working

basic.forever(() => {
    basic.showString("Hello!")
})

Can we have a global change in docs?

basic.plotImage

basic.showLeds

Why is serial only present in an isolated example of on radio received?

Serial is present on data received in this example

basic.forever(() => {
    radio.sendNumber(input.acceleration(Dimension.X))
})
radio.onDataReceived(() => {
    led.plotBarGraph(radio.receiveNumber(), 1023)
})

Serial is not present on data received in this example. Why is this the case?

let jumps = 0
basic.forever(() => {
    let acc = input.acceleration(Dimension.Y)
    if (acc > 2000) {
        jumps = jumps + 1;
        radio.sendNumber(jumps)
        basic.showLeds(`
            . . . . .
            . # . # .
            . . # . .
            # . . . #
            . # # # .
            `)
        basic.clearScreen()
    }
})
input.onButtonPressed(Button.A, () => {
    basic.showNumber(jumps)
})
input.onButtonPressed(Button.AB, () => {
    let jumps = 0
    basic.showNumber(jumps)
})
radio.onDataReceived(() => {
    basic.showNumber(radio.receiveNumber())
    led.stopAnimation()
})

music blocks - blocks to JS

1 in reference to the light beatbox lesson

http://localhost:3232/lessons/light-beatbox/activity

2 enter this code with blocks

let light = 0;
input.onButtonPressed(Button.A, () => {
    music.rest(music.beat(BeatFraction.Sixteenth));
    light = input.lightLevel();
    if (light < 25) {
        music.ringTone(music.noteFrequency(Note.C));
    }
    else {
        music.ringTone(music.noteFrequency(Note.A));
    }
});

3 press convert.

4 i would expect the code to be equal to the following when using ringTone using JS without Blocks

input.onButtonPressed(Button.A, () => {
    music.rest(BeatFraction.Sixteenth)
    let light = input.lightLevel()
    if (light < 25) {
        music.ringTone(Note.C)
    }
    else {
        music.ringTone(Note.C);
    }
})

4 however, the conversion is not 1:1. Am i missing something when using music with JS vs using music with blocks ?

1 open docs

http://localhost:3232/lessons/hero/activity

1. go to ksf, click blocks

2 search for this blocks

3 this block appears missing

Documentation not written for Serial

is showAnimation a supported API?

see this example...

http://localhost:3232/lessons/rotation-animation/quiz

if not, we should think of a global find/replace for the replacement API

1. new projects, JS
2. enter this code

let jumps = 0
basic.forever(() => {
    let acc = input.acceleration(Dimension.Y)
    if (acc > 2000) {
        jumps = jumps + 1;
        radio.sendNumber(jumps)
        basic.showLeds(`
            . . . . .
            . # . # .
            . . # . .
            # . . . #
            . # # # .
            `)
        basic.clearScreen()
    }
})
input.onButtonPressed(Button.A, () => {
    basic.showNumber(jumps)
})
input.onButtonPressed(Button.AB, () => {
    let jumps = 0
    basic.showNumber(jumps)
})
radio.onDataReceived(() => {
    basic.showNumber(radio.receiveNumber())
    led.stopAnimation()
})

Run / Compile does not work

1 click on a quiz

2 http://localhost:3232/lessons/lucky-7/quiz

3 broken tag

4 would expect this tag is still available, so there is space for a student to write their answers

what do you want to do with the teaching of collections?

http://localhost:3232/lessons/headbands

expectation: You could receive data from a single micro:bit

1. open KSF, go to JS...

2 enter this code

basic.forever(() => {
    led.plotBarGraph(input.acceleration(Dimension.X), 1023);
});

3 it would be ideal to receive Excel data from a single micro:bit using acceleration, it doesn not appear possible.

1 go to codemicrobit.com, open JS

2 enter this code

let rotating = true;
input.onButtonPressed(Button.A, () => {
    serial.writeLine("hello")
    rotating = false
})
while (rotating) {
    serial.writeLine("loop")
    basic.showLeds(`
        # . . . .
        . # . . .
        . . # . .
        . . . # .
        . . . . #
        `)
    basic.showLeds(`
        . . # . .
        . . # . .
        . . # . .
        . . # . .
        . . # . .
        `)
    basic.showLeds(`
        . . . . #
        . . . # .
        . . # . .
        . # . . .
        # . . . .

        # # # # #
        . . . . .
        . . . . .
        `)
}

3 copy this code into docs...cannot render blocks/JS

open vs code.

1 global find <br / > tags

2 global replace with amper sign

3 allow spacing for quiz and quiz answers (fix break tags)

1 open KSF, click JS

2 type this code

let hero = game.createSprite(2, 2)
let food = game.createSprite(4, 4)
let ghost = game.createSprite(0, 0)

3 would expect for these sprites to appears on the simulator.

4 the error is shown in blocks too.. see example below

4 nothing appears when pressing run

WIN10 APP - Open Project (Naming Conventions)

go to a lesson... ie.

https://codemicrobit.com/lessons/zoomer/challenges

Download .hex file

Open Program in WIN 10.

a. none of the naming of the scripts appear accurate
b. the programs are empty

the code works in the simulator, but not rendering

open KSF, enter this in JS

let basketX = 2
let eggX = 2
let eggY = 0
basic.forever(() => {
    led.unplot(basketX, 4)
    led.unplot(eggX, eggY)
    eggY = eggY + 1
    led.plot(eggX, eggY)
    basic.pause(300)
    let accX = input.acceleration(Dimension.X)
    basketX = 2 + Math.min(2, Math.max(-2, accX / 200))
    led.plot(basketX, 4)
    if (eggY > 4) {
        eggY = -1
        eggX = Math.random(5)
    }
    basic.pause(300)
})

here is the lesson

Can we make a global search for broken links?

just found this broken link from quiz to 'tutorial'...

http://localhost:3232/lessons/zoomer/quiz

we should also do a global change from /tutorial to /activity...

.../microbit/lessons/zoomer/tutorial 

should be...

.../microbit/lessons/zoomer/activity 

1 go to ksf, click js

2 enter this code

basic.forever(() => {
    radio.sendNumber(input.acceleration(Dimension.X))
})
radio.onDataReceived(() => {
    led.plotBarGraph(radio.receiveNumber(), 1023)
})

3 view the lesson

2 or click on this link

http://localhost:3232/lessons/charting/activity

is this intentional ?

1 open JS

1. type code - error free

let hero = game.createSprite(2, 2);
let food = game.createSprite(4, 4);
let ghost = game.createSprite(0, 0);
ghost.change(LedSpriteProperty.Blink, 100);

1. type code - error free

let hero = game.createSprite(2, 2)
let food = game.createSprite(4, 4)
let ghost = game.createSprite(0, 0)
ghost.change(LedSpriteProperty.Blink, 100)

you cannot rename variables in Blocks

1 open Edge

2 codemicrobit.com/lessons

3 (example) https://codemicrobit.com/lessons/charting/activity

4 i would expect the program this program to run in the simulator

1 open any lesson plan

2 for example

http://localhost:3232/lessons/beautiful-image

3 blocks don't render

Repo.

1 Go through steps to open localhost

2 Chrome opens by default

3 copy/paste localhost URL to Edge

http://localhost:3232/index.html#

4 Edge is constantly saying loading... but never finishes loading

catch the egg lesson - code not rendering - it works in simulator

catch the egg lesson ...

go to

1 spinner activity / challenge page not rendering blocks for unknown reason

2 go to activity / challenges

http://localhost:3232/lessons/spinner/challenges

3 issue is noted below

convert input light level to JS - automatic set var to 0

1 why do you need to store light level as 0?

2 enter this code in blocks

let light = input.lightLevel();

3 then press show in code

4
this is the code that appears

 let light = 0;
light = input.lightLevel();

2 i would expect when converting from blocks to JS, the code would appear like this

let light = input.lightLevel();

1. go to many part of the documentation

2 usage of showAnimation

http://localhost:3232/lessons/smiley/activity

1. this should be changed to supported API, ie. showLeds

the code is working in microbit.co.uk, not in codemicrobit.com

repro:

import code to microbit.co.uk

https://www.microbit.co.uk/jvkblk

import code to codemicrobit.com

https://codemicrobit.com/tgukzgtdzg

 let higherLimit = null;
 let voltage = null;
 let high_voltage = null;
input.onButtonPressed(Button.A, () => {
    basic.showNumber(high_voltage);
    basic.pause(2000);
});
high_voltage = 0;
higherLimit = 1024;
basic.forever(() => {
    voltage = pins.analogReadPin(AnalogPin.P0);
    if (voltage > high_voltage) {
        high_voltage = voltage;
    }
    else {
        led.plotBarGraph(voltage, higherLimit);
    }
});

here is a screenshot of the program working

when this program is loaded in codemicrobit.com, the same program is NOT working

 let voltage = null;
 let higherLimit = null;
 let high_voltage = null;
input.onButtonPressed(Button.A, () => {
    basic.showNumber(high_voltage);
    basic.pause(2000);
});
high_voltage = 0;
higherLimit = 1024;
basic.forever(() => {
    voltage = pins.analogReadPin(AnalogPin.P0);
    if (voltage > high_voltage) {
        high_voltage = voltage;
    }
    else {
        led.plotBarGraph(voltage, higherLimit);
    }
});

screenshot

the error message is ...

Voltage implicitly has an error type...

So I changed this to...

 let voltage = null;
 let higherLimit = null;
 let high_voltage = null;
input.onButtonPressed(Button.A, () => {
    basic.showNumber(high_voltage);
    basic.pause(2000);
});
high_voltage = 0;
higherLimit = 1024;
voltage = 0;
basic.forever(() => {
    voltage = pins.analogReadPin(AnalogPin.P0);
    if (voltage > high_voltage) {
        high_voltage = voltage;
    }
    else {
        led.plotBarGraph(voltage, higherLimit);
    }
});

possible issue:

the variables are not updating -> variables consistently showing Null

code was fixed 5 minutes ago, the blocks are not rendering for a second time (after fixing the code - they appeared to be fixed and visibly rendering 5 minutes ago on localhost)

    let yAccel2 = Math.abs(input.acceleration(Dimension.Y))
    let zAccel2 = Math.abs(input.acceleration(Dimension.Z))
    let sum2 = xAccel2 + yAccel2 + zAccel2
    if (sum2 < 1200) {
        basic.showLeds(`
