If you don't understand, what I wrote, you should read a tutorial or similar about switches and pullup/pulldown resistors. Maybe you can start here: [ learn.sparkfun.com/tutorials/pull-up-resistors ] | |

| Feb 27, 2018 at 14:12 | comment | added | user675319 | I'm a little confused with the resistor... If I have 9V as external supply, then I have to reduce this to 5V before carry this current to Arduino pin? | |
| Feb 27, 2018 at 13:07 | comment | added | user675319 | So I only need to use a resistor to control the voltage from sensor to arduino , thank you Chrisl. It's complicated to calculate resistance value? I've read that typical are 10k ohm, but I guess it depends on voltage provided by external battery... | |
