In this tutorial we will learn how the I2C communication protocol works and also we will make a practical example of it with the Arduino Board and a sensor which uses this protocol. You can watch the following
Well you generally don’t but since we can connect up to 128 devices (7 bit Address system) on the same I2C line and let’s say we want to connect two different LCDs on the same I2C line, than we can’t use two PCF8574 with same addresses and we need to modify one of them. So...
Description: The TCA9548A I2C Multiplexer Module is to enable to connect devices with the same I2C address (up to 8 same address I2C) hooked up to one microcontroller. The multiplexer acts as a gatekeeper, shuttling the commands to the selected set of I2C pin with your command. The multiple...
I'm going to show you how to emulate an Xbox controller with an Arduino, using a USB capable microcontroller and the ArduinoXInput library.
Connect the Seeeduino to the PC via a USB cable. Your connection should look like this: Step 4 Download theGrove I2C Motor Drive V1.3 Libraryfrom Github and install library. If you do not know how to install library for Arduino, you can refer to our guide onHow to install library. ...
I notice that the configBlock gets written to the chip every time you want to take a measurement (in the function startMeasurement). The configBlock's first byte is the device address. Is there a nice way to change the device's address t...
Learn how to use I2C to configure and read temperature and humidity from the HDC2010 with the Arduino See a demo of the HDC2010 and the LCD display See a step-by-step guide through the code so you can reproduce these results with the HDC2010 on your own ...
Connect Arduino to PC via USB cable Open Arduino IDE, select the right board and port Copy the below I2C Scanner code and open with Arduino IDE // I2C address scanner program#include<Wire.h>voidsetup(){Wire.begin();Serial.begin(9600);Serial.println("I2C Scanner");}voidloop(){byte...
The ESP8266 is 3.3V device so preferably use 3.3V I2C slaves. Many, but not all, I2C devices are are 3.3V these days. “In general, in a system where one device is at a higher voltage than another, it may be possible to connect the two devices via I2C without any level shifting ...
Once we connect the module we need to program the Arduino Board to work with the Real Time Clock. However, when it comes to programing a communication between Arduino and an I2C module the code isn’t that small and easy. Luckily, there are already several libraries for the DS3231 RTC wh...
