In case that is not there you can download it form HERE. For enabling the I2C communication we will need WIRE LIBRARAY, which should come with Arduino programing tool by default. The SDA is the data carrier signal, basically the transmission wire.Īfter we have connected the hardware properly now it is time to start the programing. The SLC is the clock signal which synchronizes the data transfer between devices and it is generated by the master device.

The two wires are: Serial Clock (SLC) and Serial Data (SDA). Simply said the signal from the master goes to all of the slaves but only the slave with the correct address is going to react on the signal. Therefore the master can easily know with which slave it communicates. I2C uses only 2 wires because each device has a unique address assigned to it. Reason for I2C easy implementation comes from the fact that only 2 wires are needed for communication, we do need to connect the devices to the common ground as well but the ground is not directly used in the communication. I2C communication is very popular and broadly used, because of its easy implementation in electronic devices.

After the basics are explained we will show an example how to blink an LED using the I2C through a serial monitor. Here we will talk about I2C communication between two Arduinos.įirst we will mention how to set up an Arduino as either a master or a slave. Added five demos: RotationResist, FaceUphill, RemoteControl, Balancing, and SumoProximitySensors.Welcome to our Instructables page. Fixed a bug in Zumo32U4ProximitySensors where the wrong array length was used.

1.1.1 (): Moved the library out of the a-star repository into its own repository.1.1.2 (): Updated the Demo example so it can compile in Arduino 1.6.7.Also incorporated some minor fixes to the QTRSensors and LSM303 libraries. 1.1.3 (): Fixed a bug that caused the buzzer's isPlaying method to malfunction sometimes when link time optimization is enabled.1.1.4 (): Fixed a bug that caused errors from the right encoder to be reported as errors from the left encoder.The examples have been updated to use this class. 1.2.0 (): Added a Zumo32U4IMU class that abstracts some details of the inertial sensors and supports different IMU types.Removed the previously bundled LSM303 and 元G libraries.

Reorganized the library's directory structure and replaced most of the bundled component libraries with Arduino Library Manager dependencies.

Use the Library Manager in version 1.8.10 or later of the Arduino software (IDE) to install this library: If you have the Zumo Shield, then you should not use this library and instead refer to the Zumo Shield documentation here. The Zumo Shield does not have an integrated microcontroller, so it must be connected to an Arduino-sized board to run. Please note that this library does NOT work with the Zumo Shield for Arduino, which is a very different product.

The user's guide for the Zumo 32U4 robot is here: It has an integrated AVR ATmega32U4 microcontroller, motor drivers, encoders, proximity sensors, line sensors, inertial sensors, buzzer, four buttons, and display screen (graphical OLED or LCD). The Zumo 32U4 robot consists of the Zumo chassis, the Zumo 32U4 Main Board, and the Zumo 32U4 Front Sensor Array. This is a C++ library for the Arduino IDE that helps access the on-board hardware of the Zumo 32U4 robot (both the newer OLED version and the original LCD version).
