Hello, i am looking to assembly a talking distance sensor with a range of 1 to 20 Ft, i think i need a waterproof lidar sensor, the control board and a mp3 playing board,instead of pulse a button each ft, the signal from the board will select the file ( instead of print or send to the lcd,will activate the recorded sounds ) have some one experience with this circuit?

Have you considered using the bottom-end RasPi? I see the RasPi Zero-W are back down to almost reasonable. You could use them headless. They have the sound capability already built-in. You could use files... or just use synthesized text-to-speech. You could also use a cheap ultra-sonic sensor.
However, what you ask is strait forward. A student of mine did projects doing the voice recorded playback and using ultrasonic sensors. Both projects are common. It shouldn't be too much of a stretch to combine them.
