Libre Mechanics it’s an Open Knowledge project created to offer a useful platform of information related with the development and research of Mechanical Engineering themes and similar fields, higly related with the use of Open Source and Software Libre tools. Here you will find a wide variety of projects, publications and scientific material available as references for developing their own projects, also guides and tutorials that allow you to take advantage of free software tools available today.
The solar tracker made with a control board low-cost Arduino using recycled materials.
A project focused on a quick and easy construction taking into account the subsequent reuse of all the elements used.
The constant control of a servo motor based on a series of photo-sensitive sensors determine the behavior of the system, the photocell powers a rechargeable 9-volt battery that supplies the energy necessary to activate the servo motor and an additional fan installed to check feeding of a photo cell.
The flat surface that supports the photo cell is automatically aligned at 90 degrees to the major source of light detected and follows the course of this in either directions of rotation of the motor. When the light source (the sun) is lost in the west the system automatically returns to its rest position to the east ready to receive the rising sun the following morning.
The following code was used in Arduino:
| int v1 = 35; | if (valor3 < 700){ | } | ||
| int v2 = 0; | a = 1; | if (a==1){ | ||
| int analog = 0; | } | v1 = v1 – 1; | ||
| int p= 0; | } | } | ||
| int servo = 2; | } | if (a==3){ | ||
| int valor1 = 0; | if (valor2 > 700) { | v1 = v1 + 1; | ||
| int valor2 = 0; | if (valor1 < 700){ | } | ||
