We’ve all seen them. The nice graphics on some blogs and how-to sites that include really nice graphics of an Arduino board with all its pins.
I want some! They’ve got to be Visio stencils or SVG files or something.
Anyone know where I can get them??
This is what I’m hoping to get accomplished….
- Temp, Pressure, Humidity monitor for the house with stats by Cacti. Ethernet Arduino required!
- Cat food dispense- dispense 1 cup daily, possibly allow cat to initiate dispensing up to 1 cup limit.
- Shower timer- time showers by listening to the water noise
- Power monitor- find a way to monitor power usage either by outlet or at the fuse box. I know there are solutions but they’re expensive and non-hackable…
- Weather station that updates to the internet- biggest hurdle here is parts…
- RFID door locks
- PC hardware monitor…I want to log the various temps on my machine but sadly all the sensors aren’t accessible via software. I hate writing windows software so this could be a creative way to do it.
The BMP085 is an analog barometer/atmospheric pressure sensor coupled with a temperature sensor. It’s analog and uses a two-wire I2C interface. I got mine from Adafruit. They include some pin headers you can solder to it or you can wire it up directly.
A great tutorial from Adafruit is here. Continue reading “BMP085 Analog Barometer & Temperature Sensor”
This was my first sensor. It’s a digital temperature and humidity sensor. It uses three pins, two for power and one for data. It worked perfectly…except….the libraries provided by Virtuabotix ($9.99 via Amazon.com) didn’t work with the Arduino IDE v1.0.
So if fixed it!

This was the first code I found to make my Arduino Ethernet do something via a web browser. I was so excited. My microcontroller could talk via ethernet!

This example shows the code to control a servo on digital pin 2 via a potentiometer on analog pin 0.
You can change the pins around via the variables in the beginning of the sketch.
