Remove the level shifter, and add 4.7k pull-ups to the 3.3v vcc on scl and sda lines. I2c chips only drive the line low, and require external resistors to pull the line high. This lets you mix voltage levels on your i2c bus fairly easily. Then you can go back to figuring out what your code is doing On my Raspberry Pi, the i2c bus is 1. Use the command i2c-detect -y 0 or i2c-detect -y 1 to verify if your Raspberry Pi detect your Arduino

Read about 'connecting RPI to arduino using i2c' on element14.com. Hi all, ive been researching on how to connect an arduino nano to a Rpi and the tutorials Ive found only explain very basic stuff. Does anyone kno Hi,nach dem die Kommunikation zwischen dem Arduino Uno und dem Raspberry Pi über USB so toll geklappt hat dachte ich mir ich kann auf mal I2C testen da ich dann auch Mikrocontroller ohne USB verwenden kann.Nach dieser Anleitung bin ich vorgegangen und e The one exception would be if you plugged in a 3.3V I2C Grove module that is non-5V tolerant into a 5V I2C Grove connector you could fry the device. In this post we discuss four simple grove projects. Project 1: Connection a Grove Fan to the Raspberry Pi. We chose three simple, yet visually interesting Grove projects. The first module is the Grove Fan module. It is The Raspberry Pi originally exposed one I2C bus on its GPIO connector, P1. It had another I2C bus dedicated to the camera connector, S5. However, with revision 2 of the Raspberry Pi, another connector was added. This was P5, squeezed in next to P1, and it also carried the second I2C bus, making it easier to get at and use. However, for some reason the two I2C buses got swapped over between. I am looking to setup a smart home and after doing a lot of research on the subject I've decided to go with a single Raspberry Pi connected to multiple Arduinos over I2C (Each Arduino would be placed into each room). The Arduino will be responsible for controlling everything in the room (Sockets, Lights, Sensors: [Temperature, Motion, etc.]). The Raspberry Pi would receive its commands from a Web Interface or other services and control the Arduinos or get information from them. This data.

If you have any problems for the serial connection or questions regarding. In this example, I am using 5 Arduinos. 1 acting as a master unit (to use I2C lingo) and 4 as slave units. The slave Arduinos wait for the master Arduino to request data then send it promptly. I am using a potentiometer plugged into the Analog 0 pin of each slave Arduino to simulate a sensor In our experiments, we took an MPU6050 and MPU9250 sensor from Invensense and connected them to a Raspberry Pi 3 as shown in the figure below. The MPU 9250 was selected as it hosts a magnetometer in addition to the accelerometer and gyroscope. The second IMU (MPU 6050) is also connected to the SCL and SDA lines. It is possible to connect multiple I2C devices on the same lines as long as they. I am trying to connect an Arduino Nano directly to a Raspberry Pi 2 over USB. This seems like it should be possible using Windows.Devices.SerialCommunication. I tried the serial sample which list all the serial devices however the Arduino does not show as a device. I can connect them using I2C but direct serial communication would be much. We want to use a 4×20 caracters Arduino LCD on the Raspberry Pi. We will use the I²C protocol and a small python class to access the display. As you can see in this picture, the LCD display has an included I²C board. You could buy it here. Wiring is based on our add a RTC clock previous tutorial . The two modules (RTC and display) could be used in pair, thanks to the I²C protocol. You.
