More traditional arduino boards such as an uno or a nano have a 5v logic level which means when you set a pin high it will measure as 5v.
Arduino logic level converter schematic.
Thanks for your help.
But how does a system or controller working with 5v logic level example arduino communicate with another system that works with 3 3v example esp8266 or any other different voltage level this scenario often occurs in many designs where there are multiple micro controllers or.
It s perfect for level shifting between devices that are sharing a data wire like i 2 c or a one wire interface.

For example i want to connect input pin to heater when heater is on from 12v circuit i get high 12v signal which processes by arduino but like everyone knows arduino can handle only 5 3 3v.
We ll examine the schematic and board layout explaining what each pin on the board does.
At the end we ll go over.

If i want to connect 4 rpi or arduino to each one lcd i needed 4 logic level converter.

Covered in this tutorial.
But other common boards such the esp8266 have a 3 3v logic level which as you can probably guess means that when you set a pin high it.

Hello stephane if you are using i2c then no.
I would like to control electrical equipment of car by arduino.
Logic levels normally refers to the high or low state of your arduino pins but not all logic levels are the same.
Modern logic voltage levels largely vary from 1 8v to 5v.
I need logical shifter not buck converter to connect arduino to car 12v circuit.
Then arduino going to change state of equipment by.
In this tutorial we ll take an in depth look at the bi directional logic level converter.
First nice job and sorry for my english.
