Verify contrast (it could be too low preventing you to see text), you can adjust contrast using the blue potentiometer on the I2C backpack. Check the I2C address ...

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...

This is a simple Arduino sketch for scanning slave address like FRAM (FM24CL16B), RTC module, I2C module for LCD, and more. I've tested on most ATmega328p MCU based boards (5V, 16 MHz) like Arduino ...

An LCD can be made to connect to a microcontroller using two wires with the aid of the I2C interface which includes pins for an SPI interface version for flexibility. The I2C LCD interface is used ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

In this project, we have the above mentioned components and the working is quite east to understand .The input will be taken from the user through the matrix keypad. At first we have to give The Hour ...
