The Sun F(ol)lower had an upgrade: It has a new, dedicated board. It simplifies the cabling a lot, and makes it quicker to (dis)assemble. As is, this board can be used as a prototyping board for reading 4 sensors (analogic input) of 10kOhm (to complete the voltage divider) and control 2 digital outputs. What's next: Now that the main board is up and running, the project can move to the next stage: -Improving the algorithm for light sensitivity in various light conditions; -Add a solar panel; -Redesign the structure to hold the servo motors, solar pannel, sensors and all the components.

Altimeter using a BMP 085 atmosferic pressure sensor and an Oled display SSD1306 128x32. This is a really simple example using two I2C devices. I've used bits and pieces from the example sketches from the devices libraries. More about connections and code here: https://github.com/LCLLajas/Simple-altimeter-with-oled-display

A quick prototyping platform with two 360º digital servo motors, 4 LDR's and a two axis joystick. The system tracks a strong source of light and the sensitivity to which it responds can be adjusted.

This is my first Instructable... A colour selector using an Arduino, Processing and an RGB LED. It enables the user to mix colours in all the visible spectrum. You can check the full Instructable here: http://www.instructables.com/id/RGB-color-selector/
