So could copy and paste the code here😢

additional futures i added bro if you want LED you can add it

Don't upload empty code bro upload any other code... After uploaded code automatically delete previous code bro ❤️

8867126724 send hi in whatsapp bro I will send code and circuit diagram bro

code work

Hi sir Code and circuit diagram I given in description please check it out sir 👆

Hello bro

Thanks for u r support bro ❤️😘

Error404 Bro please check your circuit connections once

@@Dream_Ideas_DIY i am using a power bank to power arduino could this be the issue?

@@error-ts3xt no issues bro ❤️

Hi appu thanks for watching ✨❤️

NZH creations TQ ❤ Keep Supporting

Maximum distance 4 meters / minimum distance 2 cm... if the object comes near in 15 cm it will beeps a buzzer are display as( TO CLOSE ).... FULL CODE AND CIRCUIT DIAGRAM given in diacription bro

@@Dream_Ideas_DIY Thanks a lot, I look forward trying this out. Keep up the excellent posts bro!

@@fredsampson8064 TQ bro 🤩🥰❤️❤️ keep supporting

S say bro

What happening bro

It's gives error...

Same probkem
