Today we will learn about another Serial Communication Protocol: I2C (Inter Integrated Circuits ... for demonstrating I2C communication in Arduino, we use Two Arduino UNO with Two 16X2 LCD display ...

After uploading the sketch, open the Arduino Serial Monitor (Tools > Serial Monitor). The sketch will automatically detect the I2C address of the connected LCD module and initialize it. You should see ...

As you can see in the schematic all three TC74 sensors have their SDA and SCL pins connected in series to pin A4 and A5 on the Arduino board. The two 4.7K pull-up resistors must be used when using I2C ...

If a device is found, it is reported to the Arduino serial monitor. This sketch is the first step to get the I 2 C communication working ... and plug-in I 2 C devices while the i2c_scanner is running.

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

The Nextion library folder (named "Nextion-master Arduino Uno Software Serial") contains a file named 'nexconfig.h' which is already configured to allow the communication with the display through a ...
