-# Support code to run on EV3 brick
-
-## Kernel module
-
-Kernel module is based on LEGO's `d_usbdev` module, with the addition of slightly modified `g_mass_storage`
-module from the Linux kernel. The module and supporting sources are licensed under GPLv2 (since
-they are derived from GPLv2 code).
-
-### Modifications
-
-* the `d_usbdev` uses the composite framework to register an additional mass storage function in addtion
-  to the pre-existing custom USB HID function
-* the `g_mass_storage` module has the following changes:
-  * additional `/sys/.../lun0/active` entry is added, which allows for signaling drive eject to the host
-* `d_usbdev` has an additional `ioctl()` to pretend data came from the USB host - this can be used to direct
-  the VM to do stuff
-
-### Kernel modifications
-
-The kernel itself has modified FIFO queue sizes. The LEGO kernel uses `1024` for `ep1in` and `ep1out`,
-and then `64` for `ep2` and `ep3`. Note that this is non-standard modification done with a kernel patch,
-that I didn't manage to find.  The MSD requires `512` for `ep2` and `ep3`. I have binary edited the kernel
-to do so.
-
-Note that there's 4k of FIFO memory in the hardware. If you set the queue sizes with a sum of more than
-4k, the kernel will hang, and you will not know why.
-
-## UF2 Daemon
-
-The [UF2](https://github.com/Microsoft/uf2) daemon is based on 
-[UF2 ATSAMD21](https://github.com/Microsoft/uf2-samd21) bootloader code. It exposes a virtual
-FAT16 file system over Linux Network Block Device interface (`/dev/nbd0` to be precise).
-This device is then exposed via the `g_mass_storage` module to the host computer.
-
-The Daemon is licensed under MIT.

-/*! \page imagelayout Image Layout
- *  The image consists of three different components in this fixed order: imageheader, objectheaders and byte codes.
- *
- *  The imageheader tells something about image version, filesize, no of objectheaders (objects) and no of global variable bytes.
- *
- *
- *  Objectheaders contains different informations depending on the nature of the object:
- *
- *- The VMTHREAD object (former TBC_TOPVI)                                                                              \n
- *  - OffsetToInstructions tells were to find the corresponding byte codes (offset from image start)                    \n
- *  - OwnerObjectId must be zero                                                                                        \n
- *  - TriggerCount is used but must be zero                                                                             \n
- *  - LocalBytes describes the number of bytes for local variables                                                      \n
- *
- *- The SUBCALL object   (former TBC_VI and TBC_VI_ALIAS)                                                               \n
- *  - OffsetToInstructions tells were to find the corresponding byte codes (if alias this is equal to mother object)    \n
- *  - OwnerObjectId must be zero                                                                                        \n
- *  - TriggerCount is used and must be one                                                                              \n
- *  - LocalBytes describes the number of bytes for local variables                                                      \n
- *
- *- The BLOCK object     (former CLUMP)                                                                                 \n
- *  - OffsetToInstructions tells were to find the corresponding byte codes (offset from image start)                    \n
- *  - OwnerObjectId is equal to object id it belongs to (not equal to zero)                                             \n
- *  - TriggerCount is used to determine how many triggers needed before the BLOCK object is activated                   \n
- *  - LocalBytes must be zero (locals are defined in the owner object)                                                  \n
- *
- *  Byte codes are described in a different section.
- *
- *  Little Endian are used (addresses and data are represented with LSB on lowest address and MSB on highest address).
- *
- *  Offset to instructions is number of bytes from start of image to start of object instructions.
- *
- *  Index to global variables are byte based and counted from start of globals (zero based).
- *
- *  Index to local variables are byte based and counted from start of object locals (zero based).
- *
- *  Object ID's is not zero based - First object (VMTHEAD) is named 1.

-# Patched EV3 image
-
-The file `ev3-fs.patch` summarizes the changes done to the original V1.09D image.
-You can see some text files are edited, the `d_usbdev.ko` is updated (sources in `../kernel`),
-`uf2d` added (sources in `../uf2daemon`), and a stock `nbd.ko` module is added.
-
-Additionally, the `edimax01.ko` is replaced by now much more popular `rtl8192cu.ko` (also stock).
-
-The init script has a hook for running a shell script from `/mnt/ramdisk/`. This can be used
-for testing different modules etc.
-
-The kernel command line has been modified to:
-* disable DMA for the MUSB driver - otherwise the mass storage device is very unstable
-* increase the size of dmesg buffer to 128k

+# Line Detection
+
+## Objective
+
+Design ways to improve driving safety by helping to prevent drivers from falling asleep and causing an accident.
+ 
+![Car driving on highway](/static/lessons/line-detection/car-driving.jpg)
+
+## Connect
+
+Make sure that you can answer the following questions:
+
+* Can autonomous cars react to different traffic light signals?
+* What can happen if a driver falls asleep while driving?
+* How can we detect when a driver is falling asleep?
+
+Think about what you have learned, then document it. Describe the problem in your own words. Creatively record your ideas and findings.
+
+## Construct
+
+Start by constructing this model. Read the building instructions [here](https://le-www-live-s.legocdn.com/sc/media/lessons/mindstorms-ev3/building-instructions/ev3-rem-color-sensor-down-driving-base-d30ed30610c3d6647d56e17bc64cf6e2.pdf) first.
+
+![Color sensor on the driving base](/static/lessons/line-detection/color-sensor-driving.jpg)
+
+## Program
+
+Autonomous cars need to recognize and respond to traffic lights automatically.
+First, create a program that will make your robot stop at red lights.
+Make sure your robot is only responding to the color red.
+Once you have succeeded, program your robot to drive forward again when the light changes from red to green.
+
+There are two coding tasks for this lesson:
+
+1. Create a program that will make your robot stop at red lights.
+2. Create a program that drives the robot forward until the Color Sensor sees red. The robot then stops.
+
+## Coding task 1 - Stop at red lights
+
+**Goal:** Create a program that will make your robot stop at red lights.
+
+### Step 1
+
+Create a program that drives the robot forward until the Color Sensor sees red. The robot then stops.
+
+Place a ``||motors:steer large B+C||`` block from ``||motors:Motors||`` under ``||loops:on start||``. Change the speed to 20%.
+
+```blocks 
+motors.largeBC.steer(0, 20)
+```
+
+### Step 2
+
+Place a ``||loops:while||`` loop block under ``||motors:steer large B+C||``.  
+
+```blocks
+motors.largeBC.steer(0, 20)
+while (true) {
+}
+```
+
+### Step 3
+
+Place a ``||sensors:pause for color||`` from ``||sensors:Sensors||`` inside the ``||loops:while||`` loop block. Change the color to red.
+ 
+```blocks
+motors.largeBC.steer(0, 20)
+while (true) {
+    sensors.color3.pauseForColor(ColorSensorColor.Red)
+}
+```
+
+### Step 4
+
+Place a ``||motors:stop all motors||`` block under the ``||sensors:pause for color||`` block.
+
+Study the program...what do you think the program will do?
+
+**Hint:** The motors will run until the Color Sensor senses the color red, then all motors will stop. The motors will run until the sensor reading in the while block is true.
+
+```blocks
+motors.largeBC.steer(0, 20)
+while (true) {
+    sensors.color3.pauseForColor(ColorSensorColor.Red)
+    motors.stopAllMotors()
+}
+```
+
+### Step 5
+
+Click `|Download|` and follow the instructions to get your code onto your EV3 Brick. Press the **center** button on the EV3 Brick to run the program.
+
+## Coding task 2 - Detect light changes
+
+**Goal:** Program your robot to drive forward again when the light changes from red to green.
+
+### Step 1
+
+Place a ``||loops:while||`` loop block under ``||loops:on start||``.
+
+```blocks
+while (true) {
+    
+}
+```
+
+### Step 2
+
+Place a ``||motors:steer large B+C||`` block from ``||motors:Motors||`` inside the ``||loops:while||`` loop block. Change the speed to 20%.
+
+```blocks
+while (true) {
+    motors.largeBC.steer(0, 20)
+}
+```
+ 
+### Step 4
+
+Place a ``||loops:while||`` loop block under the ``||motors:steer large B+C||``  block.
+
+```blocks
+while (true) {
+    motors.largeBC.steer(0, 20)
+    while (true) {
+        
+    }
+}
+```
+
+### Step 5
+
+Place a ``||sensors:pause for color||`` block from ``||sensors:Sensors||`` inside the ``||loops:while||`` loop block. Change the color to red.
+
+```blocks
+while (true) {
+    motors.largeBC.steer(0, 20)
+    while (true) {
+        sensors.color3.pauseForColor(ColorSensorColor.Red)
+    }
+}
+```
+
+### Step 6
+
+Place a ``||motors:stop all motors||`` block under the ``||sensors:pause for color||`` block.  
+
+```blocks
+while (true) {
+    motors.largeBC.steer(0, 20)
+    while (true) {
+        sensors.color3.pauseForColor(ColorSensorColor.Red)
+        motors.stopAllMotors()
+    }
+}
+```
+
+### Step 7
+
+Place a ``||loops:while||`` loop block under the second ``||loops:while||`` loop block.
+
+```blocks
+while (true) {
+    motors.largeBC.steer(0, 20)
+    while (true) {
+        sensors.color3.pauseForColor(ColorSensorColor.Red)
+        motors.stopAllMotors()
+    }
+    while (true) {
+        
+    }
+}
+```
+
+### Step 8
+
+Place a ``||sensors:pause for color||`` block inside the new ``||loops:while||`` loop block. Change the color to red.
+
+What do you think the program will do?
+
+**Hint:** The motors will run until the Color Sensor detects the color red, then it will stop all motors. The motors will also run and not stop when the color sensor detects the color green.
+ 
+```blocks
+while (true) {
+    motors.largeBC.steer(0, 20)
+    while (true) {
+        sensors.color3.pauseForColor(ColorSensorColor.Red)
+        motors.stopAllMotors()
+    }
+    while (true) {
+        sensors.color3.pauseForColor(ColorSensorColor.Red)
+    }
+}
+```
+
+### Step 9
+
+Click `|Download|` and follow the instructions to get your code onto your EV3 Brick. Press the **center** button on the EV3 Brick to run the program.
+ 
+## Contemplate
+
+To simulate what could happen if a driver falls asleep while driving, your robot could sound an alarm signal when it crosses the line. This feature is often available in new cars.
+
+Program your robot to perform this function.
+
+Think about what you have learned, then document it. Describe your pseudocode for this task. Creatively record your ideas, and findings.
+
+### Programming hint
+
+```blocks
+motors.largeBC.steer(0, 20)
+while (true) {
+sensors.color3.pauseForColor(ColorSensorColor.Yellow)
+music.playSoundEffect(sounds.systemGeneralAlert)
+}
+while (true) {
+    while (true) {      sensors.color3.pauseForLight(LightIntensityMode.Reflected, LightCondition.Bright)
+        motors.largeB.setSpeed(10)
+        motors.largeC.setSpeed(-10)
+    }
+    while (true) {
+        sensors.color3.pauseForLight(LightIntensityMode.Reflected, LightCondition.Bright)
+        motors.largeA.setSpeed(-10)
+        motors.largeA.setSpeed(10)
+    }
+}
+```
+
+## Continue
+
+Program your robot to drive on “autopilot” along a given route. You will need to create a program that recognizes and responds to a dark line (or white line). You will create a line-following program and your robot will need to travel along the line without losing contact with it.
+
+You will need to constantly debug your program in order to make your robot travel as smoothly as possible along the line.
+
+### Programming hint
+
+```blocks
+while (true) {
+    while (true) {   sensors.color3.pauseForLight(LightIntensityMode.Reflected, LightCondition.Bright)
+        motors.largeB.setSpeed(10)
+        motors.largeC.setSpeed(-10)
+    }
+    while (true) {
+        sensors.color3.pauseForLight(LightIntensityMode.Reflected, LightCondition.Bright)
+        motors.largeB.setSpeed(-10)
+        motors.largeC.setSpeed(10)
+    }
+}
+```
+
+## Share
+
+Consider the following questions:
+
+1. What challenged you? 
+2. Where there any surprises? 
+3. How could you improve your program?
+4. Could your program have been more streamlined? 
+5. Have you used too many blocks?
+6. Is there a more efficient way of building your program?
+7. How could your program be used in real-world scenarios?
+
+Think about what you have learned, then document it. Creatively record and present your ideas, creations, and findings.

+Design, build and program a robot that can move itself:
+
+Your robot will:
+
+* Go a distance of at least 30cm
+* Use at least one motor
+* Use NO wheels for locomotion
