Dear respected brother,
I am beginniner to use Arduino, sir i upload built-in led blink example sketch to Arduino uno and pro mini, both are blinking well, then I upload empty sketch to clear example code, system shows message that sketch upload done 100 %, but both boards runs previously blink example code. I tried to different systems (PC, Laptop,mobile) to clean an upload new sketch, but results are same, where I mistaken i don't understand. Pls help me to solve if you interested.

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

[@fredsampson8064]

What is the maximum / minimum distance this will measure?

[@Dream_Ideas_DIY]

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 )....
