for instance Arduino, you would need atleast 6 I/O pins to talk to the LCD. However, if you use an LCD module with I2C interface, you only need 2 lines to process the display information. Now a days, ...

One day you write that the macro MSBFIRST isn’t defined, and before you can go to press, it’s defined right there in Arduino.h. Great stuff! The I2C (“Wire”) library has also gotten the ...

By using a protocol called Inter-Integrated Circuit (I2C), the Wire library greatly reduces the number of wires required to connect devices. The protocol is supported on all Arduino boards ...

[Tobie’s] part of the hack is to use an Arduino and a few buttons as the controller. It’s easy to set up and we think the breadboarded controller approximates the size and weight of an LCD ...

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, ...
