The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

Arduino says the carrier board is suitable for smart cities and buildings, remote maintenance, and fleet management. More technical details can be found on the product page and documentation website.

If you’ve ever been laying out a network I2C devices inside a project box or throughout your robot’s body, you’ll probably know that I2C is not without its pitfalls. But for many … ...

This Arduino project is designed to utilize a DS3231 RTC module and Liquid Crystal I2C to display the time and temperature. A push button is required to manually turn on and off the LCD. There are two ...

This paper presents the design of an Intellectual Property (IP) that converts a serial output signal into a parallel output signal for a liquid crystal display (LCD). The IP is intended for ...

However, checking the pinout for Gravity I2C devices, it seems that every single pin is in a different spot, in particular, ground and power being reversed.

A while ago I received a couple of I/O port expander modules that use the I2C protocol. Using that Chinese module, you can use only the SDA and SCL pins ...
