Is it possible use the LCD on every pin, and change the speed of the I2C software bus, by the "Testato_SoftI2CMaster" library. "Testato_SoftI2CMaster" library need to be installed also if you want use ...

With the use of I2C, both devices just need to be connected to two PCF8574, which is an I2C IC that can be found on I2C expanding board or I2C interface that is usually used on LCD. And then, the I2C ...

There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra com… ...

Only two wires can be used from the microcontroller while the I2C bus can handle up to seven I2C LCD interfaces. An Arduino, Microchip PIC or any microcontroller with built-in or bit-banged I2C ...

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, ...

We might think that an AVR microcontroller – e.g. the ATMega328p adopted by the Arduino UNO boards – has the sufficient number of pins to manage an alphanumeric LCD. In a complex industrial machine ...
