Now i just need some help for finding the IR part, Detection range: 2~30cm. For some indication, I was inspired by the Arduino module ( https://www.amazon.fr/Infrarouge-Obstacle-Évitement-détection-visionnage/dp/B07D3Q5B95/ref=asc\_df\_B07D3Q5B95/?tag=googshopfr-21&linkCode=df0&hvadid=356456254063&hvpos=&hvnetw=g&hvrand=13637426532506141596&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9055787&hvtargid=pla-831819342408&psc=1&tag=&ref=&adgrpid=71692084549&hvpone=&hvptwo=&hvadid=356456254063&hvpos=&hvnetw=g&hvrand=13637426532506141596&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9055787&hvtargid=pla-831819342408)
