Take a stab at writing the pseudocode, I'll do the same and we'll compare notes.
When do you think you'll be ready for that?

The second sketch you posted is just needing the delay timing change. It appears the purpose of this lesson is to introduce you to pseudocode. Certainly a good thing to know, and use.

Pseudocode Traffic Lights

•	Traffic lights should have green come on first for about 3 seconds
•	Then the green light goes off and the yellow light comes on for 2 seconds
•	Then the yellow light goes off and the red comes on for 3 seconds, and the loop keeps going until the pedestrian crossing button gets pressed.
•	When the pedestrian button gets pressed the red light comes on for 5 seconds and then the original loop starts again.
•	After each light there will be a delay before the next light comes on.
•	When the void loop function runs it should have 
digitalWrite(greenLED, HIGH);
digitalWrite(yellowLED, LOW);
digitalWrite(redLED, LOW);
delay(2000)
•	Then
digitalWrite(greenLED, LOW);
digitalWrite(yellowLED, HIGH);
digitalWrite(redLED, LOW);
delay(1000)
Then
digitalWrite(GreenLED,LOW);
digitalWrite(yellowLED,LOW);
digitalWrite(RedLED,HIGH);
when button is pushed
 	if (button=HIGH); 
	RedLED, HIGH);
	Yellow and green(LOW);

I don't recall anything about a pedestrian crossing button. It's fine to use Uncle Google for research and inspiration but you need to modify what you find to fit your needs. Do you understand this line?
if (button=HIGH);

I'm glad you brought up naming your pins by their function. Do that going forward regardless what the text book does. Get into that habit now.

On Edit:

Something that will help you better understand the purpose of a lesson is to modify it. Challenge yourself. You just learned a new concept or function. Modify the code using that new knowledge to prove to yourself you understand it. Don't move on to the next lesson until you feel you mastered what you just learned.

And I'm going to challenge you right now.
At a busy intersection there can be pedestrian signs that light up Walk and Stop to tell the pedestrian when it's safe to cross the street. Let's add 2 more LEDs to do that. We'll use a white LED if you have one and a second red LED. We will modify the top portion of code to include the new LEDs. We will also need to add another delay. Here's the code we need to modify.

    digitalWrite(3, HIGH); // Turn the green LED on pin 3 ON
    digitalWrite(4, LOW); // Turn the yellow LED on pin 4 OFF
    digitalWrite(5, LOW); // Turn the red LED on pin 5 OFF
    delay(10000);
    digitalWrite(3, LOW); // Turn the green LED on pin 3 OFF
    digitalWrite(4, HIGH); // Turn the yellow LED on pin 4 ON

I'll even modify my pseudocode for you

  • Turn off Red1 and Red2. Turn on Green and White
  • Delay for 6 seconds
  • Turn off White and turn on Red2
  • Delay for 4 seconds
  • Turn off Green and turn on Yellow
  • Delay for 2 seconds
  • Turn off Yellow and turn on Red1
  • Delay for 10 seconds
    Repeat

Don't freak out. Using what you know, try to figure out how to do this. Let me know if this doesn't make sense of you get stuck.

This is how you learn.

Original pseudocode for comparison

  • Turn off Red and turn on Green
  • Delay for 10 seconds
  • Turn off Green and turn on Yellow
  • Delay for 2 seconds
  • Turn off Yellow and turn on Red
  • Delay for 10 seconds
    Repeat

I read up on your Student Kit. It didn't come with a white LED so use the blue instead.

It mentions an online platform you have access to. It states the following:

What is the difference between the open-ended projects 
and the exercises inside the lessons?

The difference between the open-ended projects
 and the exercises inside the lessons is that the exercises 
are focused on making sure the concepts have been understood. 
They provide a hands-on way of learning.

Are you utilizing this online resource? Is it not helpful?

I noticed it didn't come with a 9V power adapter but comes with a 9V battery. Are you using the battery? You might want to consider this. Get a 9V, not a 5V or 12 V

Hi,
here where I live the pedestrian button works like this:
The normal traffic light for vehicles is from green to yellow, from yellow to red and from red to green.
When someone presses the pedestrian button it's like this:
When reaching the red a buzzer starts to play and the time of the red is twice what it was normally and the buzzer is ringing while in the red.

Reads the pedestrian button every time and saves the information if it was pressed.

Changes from Green time to Yellow time to Red time,
if the information says that the button was pressed, increase the time between red and green and turn on the buzzer until the red turns off.

27

I was wanting to leave the button out of it for now. I don't know if Kid has been introduced to inputs yet. I was asking if he/she could add and control 2 more outputs.

We can circle back to this code and add the button later if needed

28

I did not see anything about the online resource.

29

I can say that I am completing the projects but when I go back in a couple of days, I don't understand the project, it's been well over a year, and I still can't get passed lesson 5.

30

Click on the link in post #3 and read the details. You actually paid for more then you are using

31

How about choosing a project you've already done, and posting it here using the </> tags?
Then you describe your difficulty in understanding it.

32

the battery is for the multimeter.

33

I have looked and I don't see anything about getting online with the Student Kit.

34

About 3/4 of the way down it reads:

How do I access the online content?

Each kit comes with a unique activation code, displayed on the inner lid of the packaging, which has to be redeemed in order to access the online content.
In order to access the online content for the first time, you will need to go to studentkit.arduino.cc, enter your activation code, select your role (educator or student), and create an account. After that, you can access the online content by logging in to studentkit.arduino.cc, with your account.

How many educators and students can be added to the platform?

Each kit allows one user (educator or student) to access the online platform. When activating your kit, you will be asked to choose if you want to use it to teach or to learn, which will determine what kind of content you see on the platform.

Start a notebook and write stuff down. That always helped me. I actually kept 2. One was my sloppy copy I used to take notes during class. I just scribbled my notes to keep up. The other one I rewrote what was in my sloppy copy all nice and neat, elaborated key takeaways, and cleaned up anything I drawn or graphed. That's the one I would study to and reference.

I agree with ruilviana. Let's take a step back and start over. We'll try to make it more structured and elaborate on what's important.

37

this is where I get lost, when you have to do the project on your own.

EXTENSION IDEAS

  • Discussion – Many modern traffic lights incorporate cameras and sensors to help determine when the light should change. Think how sensor input could be used in traffic light circuit. Where would the sensors plug into the circuit? What would we look for? What conditions should cause the lights to change?
  • Traffic Light Improvements – Identify flaws in the design of their traffic light. Then, esearch ideas and solutions to fix these flaws. Modify the circuit or code to implement solutions and improve the traffic light. For example, one flaw in the circuit is that the pedestrian button must remain pressed for the green LED to flash, but walkers cannot continue to press the button down and cross the street at the same time. How could the code be modified to read the button press but also allow walkers to cross the street? Some of the solutions to address the traffic light flaws will be addressed in Lesson 4.
  • Double Traffic Light – Many larger intersections operate multiple traffic lights at once, giving drivers increased visibility to know when to stop and when to proceed. Add another red, yellow, and green LED to the circuit in series with the original LEDs. Both red LEDs should light at the same time, both yellow lights at the same time, and both green lights at the same time. Notice what happens to the circuit as a second traffic light is added to the circuit.
  • Optimize the Code – Optimizing code is an important programming skill. It speeds up the code run time and makes the code more efficient. Look at the final sketch from Lesson 3 in the Arduino IDE. Look for ways to optimize the code by removing unnecessary commands. For example, if an LED is already off, they don’t need a second command telling the LED to turn off. Test the optimized code on the traffic light circuit to confirm it still operates as expected.
  • Pseudocode – Write pseudocode for an algorithm. Then, if you are working in groups, compare and discuss the pseudocode. Ask questions such as, “Is everyone’s code the same? How many ways are there to do a task? Which is more helpful, being broad with general instructions or being specific with detailed instructions?”

Hi there, I started off the same way as you even with the self-same kit, don't try to rush the process it comes eventually. You start copying and pasting code, then making tweaks, then realizing that doesn't work so you try to tweak it, and so on and so forth. And as for those lessons...they are not good... the UI is amazing but the same can't be said for the practicality of the lessons. Here is how I would learn Arduino if I had to do it again.

  1. Basic Circuits - Schematics, breadboarding, and such
  2. Multimeter basics - Knowing what you are turning when the instructions tell you to
  3. At this point I purchased one of those Grove Beginner Kits for Arduino and used the Arduino lessons for that...DON'T DO THIS!!! Buy a Raspberry Pi Pico W or Regular both are very cheap and very versatile, with both C++ and Python

So the code in post #22 is something you wrote? I thought it was something you got off the internet.

Do they provide a circuit or code to modify? I'm not sure what our starting point is. Have you used buttons yet?

40

Can you add these two LEDs?

41

Yes, the post #22 was my writing.
