Juan Ramón González is a technical engineer of computer systems and lives in Seville (Andalusia, Spain). For the past 9 years, he has been working on free software-based projects for the regional Ministry of Education by using Python, C++, and JavaScript, among other programming languages.

He is one of the main members of the CGA project in Andalusia (Centro de Gestión Avanzado or Advanced Management Center), which manages a network with more than 4,000 servers with Debian and 500,000 client computers that run Guadalinex, a customized Ubuntu-based operating system for Andalusian schools.

As a software developer who has a passion for electronics and astronomy, he started one of the first projects to control a telescope with the Arduino microcontroller by using a computer with the Stellarium software and a driver developed with Python to communicate with the telescope. This project's sources are published on the collaborative platform GitHub. You can see the whole code and the prototype at https://github.com/juanrmn/Arduino-Telescope-Control.
