Planet Arduino

Being new to Arduino I was a bit overwhelmed by the different ways to do things. So this is what I came up with!

I am using an Arduino UNO R3 clone but the connections I believe are the same for most Arduino’s or can be easily modified for your particular model. This project is the beginning of a UROV that I am building from the ground up and this is my first attempt to work with Arduino. I do not want to turn my UNO into a webserver if I can avoid it because of the shortage of memory and this project is just a few of the sensors that I want to use for my project. I am going to start out by using the premise that my project will eventually use RS485 to communicate serially from my UNO to the PC via a tether.

The Dht22 sensor is installed in the humidor.

The arduino takes a reading every 20 minutes, and uploads the data to your webserver.

The PHP script will record the data to the database. If the temp or humidity is out of desired range, it will send you an email alert.

Alerts must be manually cleared latter by logging into the web site, so you are not spammed, before you get a chance to fix it.

When you add water, push the select button on the LCD sheild to record it. This will be saved to the db as well. Power resets will also be recorded to the database.

See screen shot for example web report.

I’ve been looking for ways to control my Service droid robot, my Service droid robot has an ATmega2560 (with Arduino bootloader) and a Raspberry Pi. My goal is to control it over wifi. But I wanted to start with some more simpler things first. I’ve recently found some python code on letsmakerobots.com that lets me sent data over I2C from a Raspberry Pi to a micro controller.

Before getting this to work you need to configure I2C on the Raspberry Pi. Adafruit has written a nice guide how to do this. I also installed the python-SMBus package: sudo apt-get install python-smbus.

LANp combines an LED RGB Bar from an old scanner, an Arduino and Ethernet/SD Shield to make a full RGB Lamp.

It has a built-in webserver that has an RGB colour picker, which changes the LED bar in real-time.

There is some photos and a YouTube video to show it all working.
