Before we get started into programming I2C using two Arduinos. We need to learn about the Wire library used in Arduino IDE.. The library <Wire.h> is included in the program to use the following ...

Today we will correct that and learn more about I2C. We’ll also see how it can be used to exchange information between two Arduinos and how it can be used to allows one Arduino to control another one.

I2C protocol makes it easier to connect more ICs using only 2 wires SDA and SCL and allows communication between them at relatively low speed. The I2C bus or TWI (Two Wire Interface) allows a single ...

[Johngineer] found himself in need of an I2C sniffer, but didn’t have one available. Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino … ...

This is a beginner friendly project for those interested in using i2c or IIC protocol with Arduino Master and Arduino Slave. The use of other i2c peripherals such as 0.96" OLED display and MPU 6050 ...

[Wayne] wrote in to share an item he just finished working on, an I2C GPS shield for the Arduino. While other GPS solutions have existed for quite some time, his caught our eye due to its feature l… ...

(lcd display to arduino wiring) Arduino Setup. For this experiment it is necessary to download and install the “Arduino I2C LCD” library. First of all, rename the existing “LiquidCrystal” library ...

Some Arduino boards feature the I2C pins in different places, ... Implementing Arduino's Wire library into your projects is an easy process that shouldn't take up too much time.

RS-485 in Arduino. For using RS-485 in Arduino, a module called 5V MAX485 TTL to RS485 which is based on Maxim MAX485 IC is needed as it allows serial communication over long distance of 1200 meters ...

Another difference between the Rev3 and R4 WiFi is the number of their serial ports and I2C buses. The Rev3 has a single serial connection, shared by the USB port and the RX/TX pins. There's also ...
