What to do when you have two I2C devices with the same address? Need additional I2C channels? Here’s a easy to use analog switch to enable 3 separate I2C channels. A MAX4562 and a handful of pullup resistors might be
We have been working on our Real Time Clock and LCD display as a snap on “shield” (no wiring). This will provide not only a time date function, but clock and display functions to other projects. We ran across another
With a bunch of help from John Boxall of Tronixstuff.com, we finally got the Time / Date functions working on our Arduino, with the DS1307 breakout board from Sparkfun. Thanks John.

I ported our temp / humidity (and not quite right barometric pressure) project over to the Mega 2560 a few minutes ago. So many more I/O pins. I love it! Will continue working on time date functions, and getting the
Today is Arduino day. First off, I grabbed the new BMP085 module from Sparkfun, and modified the examples to talk to my lcd instead of serial output. It’s displaying “Temperature -2678 Pressure 52029” which can’t be right, so I whipped
From http://www.arduino.cc/en/Tutorial/X10 This library enables you to send and receive X10 commands from an Arduino module. X10 is a synchronous serial protocol that travels over AC power lines, sending a bit every time the AC power crosses zero volts. It’s
