Nice ♥♥♥

[@ThinkingThings-q4p]

Thank you! Cheers!

[@faizanhaque8805]

amazing video buddy! make more amazing projects like this

[@ThinkingThings-q4p]

Thanks so much, I really appreciate it! A like, sub, and share would help me a lot at this stage!

[@Amy-kh3zl]

Nice video!!!
can you make a simple/mid project using esp32,how to use potentiometer with it,and further explain how to use joystick and the pins?👌👍

[@ThinkingThings-q4p]

@@Amy-kh3zl Thank you for the feedback!! Yes, that's a great suggestion! :) I just started, subs shares and like would really help me a lot to grow and keep making video like this! :)

[@ThinkingThings-q4p]

I made the Joystick tutorial! :)

[@Adrian-od8iu]

same code for windows? also still waiting on your code, i have some cool ideas to add

[@ThinkingThings-q4p]

Yes, i am using the Arduino IDE that you can use also on Windows. I am planning to make a GitHub to release the code, stay tuned!

CODE???????????????????

[@ThinkingThings-q4p]

Hi!! Thank you for your interest, I am planning to create a GitHub repository soon, to release codes. Stay tuned!
Consider that any sub like and share woul really help me a lot at this stage!

Meanwhile I am pasting it here below.
Consider that a like a share and a sub would greatly help me at this stage.
Let me know if it works.

Hello! Thank you so much for your interest! I'm planning to create a GitHub repository soon to share my codes, so stay tuned for updates.
Your support through subscribing, liking, and sharing would mean the world to me and help me grow at this stage!

[@karelbenda5322]

@@ThinkingThings-q4p My support through subscribing, liking, and sharing only makes sense if your channel is useful to me. If the author doesn't bother to publish the code, I won't support, like, or subscribe. It makes no sense. No code = no like or channel subscription.

[@ThinkingThings-q4p]

@@karelbenda5322 Thank you for your feedback! I understand how helpful having access to the code can be, and I truly appreciate your perspective. My channel focuses on sharing ideas, demonstrations, and inspiration for DIY projects. As I mentioned, I plan to create a GitHub repository soon to share my projects more broadly.
Of course, the choice to subscribe is entirely yours, and I respect that. Thanks again for your input, and I hope to see you around!
