The I2c can run at different logic voltage levels.

In this article I’m going to discuss the two methods of interfacing the Arduino with the raspberry Pie and handling there 3.3v and 5v logic difference. I would appreciate your support in this way! I may make a commission if you buy the components through these links. Oled HDMI touch display for raspberry pi: Wireless Keyboard and Mouse for raspberry pi: They have several digital I/O ports, they have several analog i/o ports, they have analog to digital converters, they can handle interrupts, they can do timing very precisely, so by putting the two of them together, amazing advanced level projects can be designed. By interfacing these 3.3v and 5v logics, we create a powerful combination the raspberry pie obviously is a full-fledged microcomputer capable of running python, capable of connecting to the internet, natively several of these have Bluetooth and Wi-Fi on them, but one thing in which they are not powerful is i/o this is the place where Arduino excel because Arduino are well known for their i/o basic input output operations. As we know that a raspberry pie uses 3.3v logic on its GPIO pins where most of the Arduino boards uses 5v, although there are 3.3v Arduino boards.

it is a very common application to interface 5v and 3.3 volt logic. The i2c has voltage levels that varies the most, commonly used voltage levels are 5v and 3.3v. There are many i2c buses with 4 pins but not necessarily they have the same order. The inter-integrated bus has no standard connector for I2c unlike things like USB, there are a variety connector you can use, there is a small Molex connector that many manufacturers have latched on it but it by no mean a standard, a lot of people simply use DuPont pins and even in that case there is no standard as to what the pin note. In this article we will be interfacing 3.3v logic raspberry pie with a 5v logic Arduino board. By connecting Arduino with Raspberry Pi we can do so many amazing things. Arduino and Raspberry Pie both are the most famous and frequently used boards. But I never used them together in a single project.
