Make a program to follow a line using the Color sensor and reflected light.
|
||||
Make a program to follow a line using the Color sensor and reflected light. Let's test reflected light to see if it's white or black (on the line), and drive our robot accordingly.
|
||||
|
||||
|
||||
|
||||
## Step 1
|
||||
|
||||
We are going to test and see if the reflected light is white (outside the line) or black (on the line), and drive our robot accordingly. Open the ``||logic:Logic||`` Toolbox drawer. From the **Conditionals** section, drag out an ``||logic:If then else||`` block onto the Workspace, and drop it into the ``||loops:forever||`` loop.
|
||||
In the ``||logic:Logic||`` Toolbox drawer under the **Conditionals** section, drag out an ``||logic:If then else||`` block onto the Workspace, and drop it into the ``||loops:forever||`` loop.
|
||||
|
||||
```blocks
|
||||
forever(function () {
|
||||
if (true) {
|
||||
|
||||
} else {
|
||||
|
||||
}
|
||||
forever(function () {
|
||||
if (true) {
|
||||
|
||||
} else {
|
||||
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
## Step 2
|
||||
|
||||
Open the ``||logic:Logic||`` Toolbox drawer again. From the **Comparison** section, drag out ``||logic:0 < 0||`` comparison block onto the Workspace, and drop it into the ``||logic:if then else||`` block, replacing ``true``.
|
||||
Open the ``||logic:Logic||`` Toolbox drawer again. From the **Comparison** section, drag out ``||logic:0 < 0||`` comparison block and drop it into the ``||logic:if then else||`` block, replacing ``true``.
|
||||
|
||||
```blocks
|
||||
forever(function () {
|
||||
if (0 < 0) {
|
||||
|
||||
} else {
|
||||
|
||||
}
|
||||
forever(function () {
|
||||
if (0 < 0) {
|
||||
|
||||
} else {
|
||||
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
## Step 3
|
||||
|
||||
Open the ``||sensors:Sensors||`` Toolbox drawer. From the **Color Sensor** section, drag out a ``||sensors:color sensor light||`` value block onto the Workspace, and drop it into the first slot of the ``||logic:0 < 0||`` comparison block, replacing the `0`.
|
||||
Open the ``||sensors:Sensors||`` Toolbox drawer. From the **Color Sensor** section, drag out a ``||sensors:color sensor light||`` value block and drop it into the second slot of the ``||logic:0 < 0||`` comparison block, replacing the `0`.
|
||||
|
||||
```blocks
|
||||
forever(function () {
|
||||
if (sensors.color3.light(LightIntensityMode.Reflected) < 0) {
|
||||
|
||||
} else {
|
||||
|
||||
}
|
||||
forever(function () {
|
||||
if (0 < sensors.color3.light(LightIntensityMode.Reflected)) {
|
||||
|
||||
} else {
|
||||
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
## Step 4
|
||||
|
||||
If the value of the reflected light is greater than 40% (white or very light) then our robot is outside the line, and we should steer it to the left. In the ``||logic:0 < 0||`` comparison block, click the operator drop-down menu to change from ``<`` to ``>`` comparison, and change the compared value to `40` replacing `0`.
|
||||
|
||||
|
||||
If the value of the reflected light is greater than 40% (white or very light), our robot is outside the line, so steer to the left. In the ``||logic:0 < 0||`` comparison block change the compared value to `40` replacing `0`.
|
||||
|
||||
```blocks
|
||||
forever(function () {
|
||||
if (sensors.color3.light(LightIntensityMode.Reflected) > 40) {

Open the ``||motors:Motors||`` Toolbox drawer. Drag out **2** ``||motors:tank large motors||`` blocks onto the Workspace, and drop one of them into the ``||logic:if||`` part, and the other into the ``||logic:else||`` part of the ``||logic:if then else||`` block.
