[Johngineer] found himself in need of an I2C sniffer, but didn’t have one available. Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino … ...

To display the caller’s information, [Dilshan] is using an Arduino Uno and common 16×2 HD44780 LCD. As a nice touch, the code will even blink the Arduino’s onboard LED when you’ve missed a ...

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, ...

An Arduino, Microchip PIC or any microcontroller with built-in or bit-banged I2C interface can also be used with the I2C LCD interface. A different port expander is used to create an SPI device using ...

As promised in the first part of this article, now it is time to see in detail how we can use the Alphanumeric LCD Display in our Arduino sketches. The idea beside this project is to give a simple ...

Use an ATtiny85 to display sensor values on an I2C LCD (equiped with PCF8574): GY21P (Si7021+SHT21) I2C sensor, temperature and relative humidity DS18b20 Dallas sensor, one wire, temperature I had ...
