Step 1 @showdialog

Welcome to Bees Coding Tutorial. built project

Step 2 @showdialog

In this coding tutorial we will count the number of pollinators visiting your garden monitor, whenever a pollinator lands on the touch sensor all pixels of the LED Ring are turned on. Also a bar graph is plotted on the Microbit LED matrix. Button A clears the screen and shows the number of total pollinators.

Step 3 @showdialog

Turn on the Climate Action Kit board. breakout board

Step 4 @showhint

Click three dots besides |Download| button, and click on Connect Device. Next, follow the steps to pair your micro:bit. pair gif

Step 5 @showhint

Next, click the |Download| button to download the blank project to start-up the simulators.

Step 6 @showhint

Look below the @boardname@ simulator to see the Climate Action Board’s simulator of the connected components. Try touching the Touch Sensor on your project. The virtual simulators will react to it. touch

Step 7

Click ||Variables:Variables||. Click on |Make a Variable| to create a new ||Variables:Variable||.
Name it ||Variables:bugVisits||.

Step 8

Inside ||Variables:Variables|| there is ||Variables:bugVisits|| and more blocks.

Step 9

Click ||Variables:Variables|| drag and drop ||Variables:set bugVisits to 0|| block inside ||basic:on start|| block.

let bugVisits = 0
basic.forever(function (){
})

Step 10

Click ||logic:Logic|| drag and drop ||logic:if true then|| conditional block inside ||basic:forever|| loop.

let bugVisits = 0
basic.forever(function (){
 if (true){
 }
})

Step 11

Click ||fwdSensors:Sensors|| drag and drop ||fwdSensors:touch pressed|| block to replace ||logic:true|| condition of ||logic:if true then|| block.

let bugVisits = 0
basic.forever(function () {
    if (fwdSensors.touch.fwdIsPressed()) {
            }
})

Step 12

Click ||Variables:Variables|| drag and drop ||Variables:change bugVisits by 1|| block inside ||logic:if|| ||fwdSensors:touch pressed|| ||logic: then|| block.

let bugVisits = 0
basic.forever(function () {
    if (fwdSensors.touch.fwdIsPressed()) {
        bugVisits += 1
        }
})

Step 13

Click ||fwdSensors:Sensors|| drag and drop ||fwdSensors:set all ledRing LEDs to|| block under ||Variables:change bugVisits by 1|| block.

let bugVisits = 0
basic.forever(function () {
    if (fwdSensors.touch.fwdIsPressed()) {
        bugVisits += 1
        fwdSensors.ledRing.fwdSetAllPixelsColour(0xff0000)
        }
})

Step 14

Click ||basic:Basic|| drag and drop ||basic:show number|| block under ||fwdSensors:set all ledRing LEDs to|| block.

let bugVisits = 0
basic.forever(function () {
    if (fwdSensors.touch.fwdIsPressed()) {
        bugVisits += 1
        fwdSensors.ledRing.fwdSetAllPixelsColour(0xff0000)
        }
})

Step 15

Click ||fwdSensors:Sensors|| drag and drop ||fwdSensors:set all ledRing LEDs to|| block under ||basic:show number|| block.

let bugVisits = 0
basic.forever(function () {
    if (fwdSensors.touch.fwdIsPressed()) {
        bugVisits += 1
        fwdSensors.ledRing.fwdSetAllPixelsColour(0xff0000)
        fwdSensors.ledRing.fwdSetAllPixelsColour(0x000000)
    }
})

Step 16

Click ||Variables:Variables|| drag and drop ||Variables:bugVisits|| to replace the ||0|| in both ||basic:show number||. Change the color of second ||fwdSensors:LED Ring|| block to ||control:Black||.

let bugVisits = 1
basic.forever(function () {
    if (fwdSensors.touch.fwdIsPressed()) {
        bugVisits += 1
        fwdSensors.ledRing.fwdSetAllPixelsColour(0xff0000)
        fwdSensors.ledRing.fwdSetAllPixelsColour(0x000000)
    }
})

Step 17

Click ||LED:LED|| drag and drop ||LED: plot bar graph of 0 upto 0|| block under ||fwdSensors:set all pixels colour|| block

let bugVisits = 0
bugVisits = 0
basic.forever(function () {
    if (fwdSensors.touch.fwdIsPressed()) {
        bugVisits += 1
        fwdSensors.ledRing.fwdSetAllPixelsColour(0xff0000)
        fwdSensors.ledRing.fwdSetAllPixelsColour(0x000000)
        led.plotBarGraph(0,0)
    }
})

Step 18

Click ||Variables:Variables|| drag and drop ||Variables:bugVisits|| block to replace ||0|| in ||LED:plot bar grap of 0|| block. Change ||LED:upto 0|| to ||25||

let bugVisits = 0
bugVisits = 0
basic.forever(function () {
    if (fwdSensors.touch.fwdIsPressed()) {
        bugVisits += 1
        fwdSensors.ledRing.fwdSetAllPixelsColour(0xff0000)
        fwdSensors.ledRing.fwdSetAllPixelsColour(0x000000)
        led.plotBarGraph(
        bugVisits,
        25
        )
    }
})

Step 19

Click ||Input:Input|| drag and drop ||Input:on button A pressed|| block on the workspace.

input.onButtonPressed(Button.A, function () {
})
let bugVisits = 0
bugVisits = 0
basic.forever(function () {
    if (fwdSensors.touch.fwdIsPressed()) {
        bugVisits += 1
        fwdSensors.ledRing.fwdSetAllPixelsColour(0xff0000)
        fwdSensors.ledRing.fwdSetAllPixelsColour(0x000000)
        led.plotBarGraph(
        bugVisits,
        25
        )
    }
})

Step 20

Click ||Basic:Basic|| drag and drop ||Basic:clear screen|| block inside ||Input:on button A pressed|| block.

input.onButtonPressed(Button.A, function () {
    basic.clearScreen()
})
let bugVisits = 0
bugVisits = 0
basic.forever(function () {

        bugVisits += 1
        fwdSensors.ledRing.fwdSetAllPixelsColour(0xff0000)
        fwdSensors.ledRing.fwdSetAllPixelsColour(0x000000)
        led.plotBarGraph(
        bugVisits,
        25
        )
    }
})

Step 21

Click ||Basic:Basic|| drag and drop ||Basic:show number|| block under ||Basic:clear screen|| block. Click ||Variables:Variables|| drag and drop ||Variables:bugVisits|| block to replace ||0|| in ||Basic:show number|| block.

input.onButtonPressed(Button.A, function () {
    basic.clearScreen()
    basic.showNumber(bugVisits)
})
let bugVisits = 0
bugVisits = 0
basic.forever(function () {
    if (fwdSensors.touch.fwdIsPressed()) {
        bugVisits += 1
        fwdSensors.ledRing.fwdSetAllPixelsColour(0xff0000)
        fwdSensors.ledRing.fwdSetAllPixelsColour(0x000000)
        led.plotBarGraph(
        bugVisits,
        25
        )
    }
})

Step 22

Click ||Basic:Basic|| drag and drop ||Basic:pause (ms) 100|| block under ||Basic:show number|| ||Variables:bugVisits|| block. Click ||Basic:Basic|| drag and drop ||Basic:pause (ms) 100|| block under ||Basic:clear screen|| block under ||Basic:pause (ms) 100|| block. Change ||100|| of ||Basic:pause (ms) 100|| block to ||Basic:5000||.

input.onButtonPressed(Button.A, function () {
    basic.clearScreen()
    basic.showNumber(bugVisits)
    basic.pause(5000)
    basic.clearScreen()
})
let bugVisits = 0
bugVisits = 0
basic.forever(function () {
    if (fwdSensors.touch.fwdIsPressed()) {
        bugVisits += 1
        fwdSensors.ledRing.fwdSetAllPixelsColour(0xff0000)
        fwdSensors.ledRing.fwdSetAllPixelsColour(0x000000)
        led.plotBarGraph(
        bugVisits,
        25
        )
    }
