Introduction and video solution to exercises

[RishitModi]

Hi JdeRobot Team!

I'm Rishit Modi, a 2nd-year CS student at VJTI, Mumbai. I’ve been enjoying the RoboticsAcademy exercises and am now diving into Visual Circuit.

While setting up on Ubuntu 20.04 (WSL), upon running the
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
command, as mentioned in the installation guide,I ran into a deprecation warning indicating that Node.js 14 and its installation script are outdated and should be replaced with a supported version.

I resolved this by installing Node.js v14.4 by first installing NVM (version manager) and then using it to download and switch to Node 14.4.0 specifically.

I’m moving on to solving exercises using Visual Circuit now. Would you like me to submit a PR updating the installation steps with this workaround? It could help others avoid the same issue.

Best,

Rishit Modi

I have set up the frontend and backend locally as per the user manual of Visual Circuit, but while trying out the Build your first application tutorial, upon doing the build and download step, it shows the error of failing to fetch.

The terminal shows no errors/warnings, hence I haven't been able to debug what's causing it. Could you please guide through what should i do to resolve it?

Attaching a video run-through of the same.

Could you please verify the backend on port 8080? In your video, it is running on 8000. You can refer to the README for instructions on running it locally.

Thank You @BkPankaj
Yes you're right its running in 8000.
I had been referring to https://jderobot.github.io/VisualCircuit/install/ for the purpose and maybe there's a typo there.

I will refer to the READMEs and redo the setup and get back to you.

It does work now.

Thank You.
