In the long past I saw my mom waking up to turning on the water pump at midnight almost everyday and waiting to full fill the water box and then, back to sleep, to go work few times later.
As a child I didn't happy watching this situation. So, when I saw an article, reading an electronic magazine called by "APE - Aprendendo e praticando eletrônica", there was a project explaining how to build a water level using operational amplifier, that time is was LM741. I bought it and installed in my home. I did not know anything about electronic, everything I have learnt was reading the project path on this article.
When my mom has arrived at the end of the day the project was in working and filling the water tank accordangly, turning on and off the water pump.
Since that time and nowadays, electronics projects are part of my life.
Hello, my name is Andre Pereira da Silva, I am industrial technician, have electronic engineering course on UERJ and studying Physics on UFRJ, Rio de Janeiro, Brazil.
Here we are one of the most poor country known in the world, with severe inequalities and maybe, the worst educational system, carrying an historical cultor for corruption in any level of the society. But this is changing. More and more people here are trying to do a better Brazil to the world. Working in good education system, in tecnology and changing the politician culture to achieve a knowledgment to more people we can.
If you are planning to come to Brazil, take care. But you will find many good persons to talk about tecnology, like me.
This file can be found on SDK2.0 archive at SDK2.0->boards->frdmk82f->driver_examples->gpio->led_output. In KDS_V3 uoy need to import the project and find those files to change, I mean, "pin_mux, board and gpio_led_output"
