Hello.
I'm Pepper Daddy from the Coding Beginner Rescue Team.
While following along with the exercises in a course, you may sometimes think you did everything exactly as shown in the video, yet it does not work, or you may encounter an unexpected error. In such cases, please don't spend too long trying to figure it out on your own—feel free to leave a question.
However, if you also provide the information below, we can narrow down the scope of the problem much more quickly.
Which course and which exercise
How far it proceeded normally
What result you expected
What actually happens
The command you ran and the error message
If possible, include the code you wrote and a photo of the wiring
For example,
❌ "The GPIO exercise isn't working."
Rather than
⭕ "I'm working on the GPIO output exercise. The program runs normally without any errors, but the LED does not turn on. I used GPIO pin XX, and the current wiring and code are as follows."
Or,
❌ "SSH connection does not work."
Rather than
⭕ "The Raspberry Pi and PC are connected to the same router, and ping works normally. ssh jcrt@192.168.x.xWhen I run it, Permission denied (publickey)is displayed."
It would be helpful if you provided details like this.
As you write your question, organizing “what is working properly and where the problem starts” is itself good debugging practice. If you still don’t know, that’s okay. Just write down as much as you know, and we’ll look into it together.
If you get stuck while taking the course, feel free to leave a question anytime.
Thank you.
