I know what you blog needs. Pictures of your new band. And the friends and acquaintances of your new band. Yes.

Okay I have called him... scratch that off the TODO list.

Ardunio and the SHT15

For my ongoing thermostat project I require some sort of temperature and humidity sensor. Because I'm fairly new to all this I decided to get a 2 in 1 sensor from Robotshop called the SHT15. I went with the SHT15 because it had both a temperature and humidity sensor and uses a "digital 2-wire" interface. When I first purchased it I didn't realize that "digital 2-wire" didn't mean I2C, but that's another story.

In order to get the sensor to communicate with the Arduino I needed to write some custom code that manipulates the data and clock lines by pulling them high and low at the correct times. I haven't had any experience doing this before so it was a learning experience for me.

Connecting the SHT15 to the Arduino is pretty simple. The data and sck lines each goto a digital input/output on the Arduino and the VCC goes to +5V. Pretty simple. Here is a picture of my breadboard.



As you can see I had to solder on some breadboard wires onto th…

Arduino LED MIDI Controller

It's been a while since I've made a post so I have decided that it was about time I did. This time I'll be talking about my Haunted House I made.

I started with the idea to take a Halloween decoration (small haunted house) and add some LEDs to it and make them blink. What I ended up with was a haunted house with 6 LEDs in it all controlled by MIDI. I used an Arduino to receive MIDI signals from my computer and turn on/off LED lights based on those signals.

Check out the video...




The "MIDI to Arduino Breakout Board" as I call it in the video I designed myself. I used various resources on MIDI around the web and came up with this schematic.




Digikey Part list:

2 x DIN5 - CP-2350-ND
2 x 6N138 - 516-1600-5-ND
1 x diode - 1N914B-ND
2 x 220 ohm resistor
1 x 270 ohm resistor


As you can see it isn't very complicated. The hardest part was finding in DIN5 part numbers at Digikey. The code on the other hand was a bit more complicated. The trick was to decode the …

Thermostat project

It's that time of year again. Winter has hit full force here. I've been on an Arduino kick lately and came up with an idea for a project to battle the cold weather. A thermostat connected to your home network!! Why would you want to do that you ask? The answer is simple, I want to be able to control the temperature of my house from anywhere! If security is a concern then you could limit control to your local network (but that's another discussion).

Hardware:
First you would start with a gumstix connex 200xm along with a rs232 expansion board and an ethernet expansion board with a microSD interface for more storage. You could also go WiFi if you so desire. You will also need a temperature and humidity sensor with a serial interface.

Software:
The software system would be as simple as running a LAMP (Linux, Apache, Mysql, PHP) server. Of course I would have to develop some software to get the temperature readings from from the sensors and for controlling the furnace. …
