Arduino 4-legged Robot - Stalker

I am going to build an Arduino Quadruped Robot. As usual, I will share my source code and show as many pictures as possible, to help those of you who are also building Quadruped robots. The way I do things might not be the best ways, and I am sure you can come up with better solutions, please let me know if you do!

First Android App controls android via bluetooth LEDs

A fairly simple one. I will only describe how the seek bar works, and part of how commands are recognized by arduino (arduino code). I will do another one about bluetooth another day.

Weibo Security System (IR sensor, arduino, php, VB)

23/05/2012

I am renting at the moment but doors have no locks, so i am planning to build a system that sends me a warning whenever the doors is cracked open. I am think to use Weibo (twitter in China), and email. it will also activate the CCTV system and start recording.


The following is the diagram that roughly explains how it works.

现在租房，但门没有锁所以打算做个微博警报器，门要是一打开，电脑就会发微博并 @梁小航OSCAR （我）。原理大概像这图吧，画得不好。最难的部份：用第三方软件发微博的代码已经拼出来了，下一步就是写 PHP 跟 VB 的 interface，最后就写 Arduino跟sensor的代码。。
