A third year Electronic Engineering project completed by myself at University of Exeter, titled "Research, Design and Prototype an Energy Efficient Dual Axis Solar Tracker", 2011.

This prototype was achieved by initial background and related research which also overviewed the use of solar energy. The research includes reasoning for dual axis solar trackers such as increasing the efficiency of a solar panel as it can rotate and angle to face the sun. From this research it was decided that including programming would be appropriate for the system and so the use of a programmable interface controller (PIC) was selected to control the system.
After research, part selection and design ideas, a flowchart outlining the main intentions for the programming was drawn up. This was then implemented by programming the PIC using a code written in Assembly language. This code was written in sections and tested to reveal complications with more than two analogue readings. So an alternative solution was developed making use of more than one PIC to achieve the aims that were set down in the original design. Testing the system was made possible by the use of natural sunlight and by using desk lamps to simulate the sun.
