Hello. I need one capacitive proximity sensor and two inductive proximity sensors for my Arduino project. The sensors need 6-36 V to work and I know that Arduino works with 5 V. How do I connect all three of my sensors to one Arduino board? I was planning to use a 9V battery for each of my sensors but I don't know how to connect them to Arduino at the same time? ---

@amiraakm Please post the datasheets for the sensors ---

HI, @amiraakm Welcome to the forum. > [@How to get the best out of this forum](https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum/679966): > > See also [FAQ - Arduino Forum](https://forum.arduino.cc/faq) for general rules on forum behavior and etiquette. Hello, Welcome to the Arduino Forum. This guide explains how to get the best out of this forum. Please read and follow the instructions below. Being new here you might think this is having rules for the sake of rules, but that is not the case. If you don’t follow the guidelines all that happens is there is a long exchange of posts while we try to get you to tell us what we need in order to help you, which is frus… What model Arduino are you using? Can you please tell us your electronics, programming, arduino, hardware experience? Thanks.. Tom... πŸ˜ƒ πŸ‘ β˜• πŸ‡¦πŸ‡Ί ---

Hi, thank you. I'm using ARDUINO UNO R3 ATMEGA328P-AU. I have experience with C programming, but practically no experience with hardware or arduino. I just started learning Arduino last month. I was planning to make a garbage bin that can identify metal cans apart from plastic bottles. ---
