Arduino talking to an I2C LCD display

By Anton Piatek, on January 17th, 2011%

I had a spare Matrix Orbital 20×4 character LCD floating about so I decided to try and connect it up to my Arduino. The display is a LK204-25, which is a brilliant little serial display, with support for a 25 button keypad and six outputs that can be used to control power to something else.

Fix your Arduino Uno for Linux

By Anton Piatek, on December 13th, 2010%

Are you using an Arduino Uno on Linux? If so, you may have noticed that writing to the serial port in a loop can cause the Arduino Editor/Programmer software to appear to lock up, or even Linux having trouble using the serial port for your Uno.

It turns out there was a bug in the . . . → Read More: Fix your Arduino Uno for Linux

Arduino 1-wire temperature sensors

By Anton Piatek, on December 13th, 2010%

So you have played a bit with your Arduino, and have heard about other people using it to monitor the temperature, but weren’t sure how they did it – Here is how I did.

Maxim make a very simple 1-wire temperature sensor – the DS18B20 (the replacement to the DS1820). This 3 pin sensor looks . . . → Read More: Arduino 1-wire temperature sensors
