In this tutorial we will learn how the I2C communication protocol works, as well as, make a practical example of Arduino I2C communication with...
Connect I2C sensor/device to Arduino (SCL, SDA,VCC, GND pins) 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();Se...
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...
If you want to build your own temperature monitoring system or to measure the altitude of your drone or simply want to measure the atmospheric pressure in your area, then one of the best module for you to use in your project is the BMP280 Pressure sensor

How to Connect a Serial LCD to an Arduino UNO: In this instructable I will show you how I connected a serial LCD 16X2 to an Arduino UNO. There are lots of instructables and tutorials showing you how to connect a regular LCD to an Arduino but not many sho
A how-to on using an I2C LCD display with the ESP32 using Arduino IDE from Random Nerd Tutorials: This tutorial shows how to use the I2C LCD (Liquid Crystal Display) with the ESP32 using Arduino IDE. We’ll show you how to wire the display, install the library and try sample code ...
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...
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...
