Step 1 @showdialog

Welcome to Advanced Agriculture Coding Tutorial built project

Step 2 @showdialog

In this coding tutorial we will build a moisture level indicator using the LED Ring's pixels.

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 and the connected sensors. Try holding the Moisture Sensor or dipping it in a glass of water. See how the virtual simulators react. moisture

    }
    if(fwdSensors.soilMoisture1.fwdIsMoistureLevelPastThreshold(5, fwdSensors.ThresholdDirection.Over)){
    }
    if(fwdSensors.soilMoisture1.fwdIsMoistureLevelPastThreshold(5, fwdSensors.ThresholdDirection.Over)){
    }
    if(fwdSensors.soilMoisture1.fwdIsMoistureLevelPastThreshold(5, fwdSensors.ThresholdDirection.Over)){
    }
})

Step 16

Click ||fwdSensors:Sensors|| drag and drop ||fwdSensors:set all ledRing LEDs to|| block under ||fwdSensors:soilMoisture1 level is over|| block.

basic.forever(function () {
    if (fwdSensors.soilMoisture1.fwdIsMoistureLevelPastThreshold(50, fwdSensors.ThresholdDirection.Over)) {

Step 18

Right click ||fwdSensors:set ledRing 0|| block and duplicate it. Each ||Logic:If|| ||fwdSensors:soilMoisture1 is over|| ||Logic:then|| block should have ||fwdSensors:2 set ledRing 0|| blocks inside the ||Logic:If condition|| block.

basic.forever(function () {
    if (fwdSensors.soilMoisture1.fwdIsMoistureLevelPastThreshold(50, fwdSensors.ThresholdDirection.Over)) {

        fwdSensors.ledRing.fwdSetPixelColour(0, 0xff0000)
    }
})

Step 20

Change the ||fwdSensors:LED Ring pixel values|| in pairs.

  • Pair 1
  • ||fwdSensors:set ledRing 0 to 5||
  • ||fwdSensors:set ledRing 0 to 4||
  • Pair 2
  • ||fwdSensors:set ledRing 0 to 3||
  • ||fwdSensors:set ledRing 0 to 2||
  • Pair 3
