In general when we want to integrate Java with Arduino we can use the serial port for interaction, where arduino will receive commands and also write sensors information. This is greatly explained on JavaFX 8: Introduction by Example book on Arduino chapter. The problem with this approach is that you will end having to maintain two distinct codes in two different languages. Another approach is use JArduino , which allows you to write Java code to directly interact with arduino! What you should do is follow the procedure from README file in JArduino page to install the firmware in your arduino board, then build a maven project that has jarduino as a maven dependency to start building Java applications that uses arduino. Since it is Java we can use JavaFX, JavaEE and all the Java APIs! Problems I always start writing before having something working (that's the reason why I had more than 50 draft posts on this blog). So I faced some unwanted issue and I had to figure out a few...

I have been having fun with Arduino these days! In this article I am going to show how did I use an electret mic with Arduino to create a Dancing Lights circuit. Dancing Lights   I used to be an eletronician before starting the IT college. I had my own electronics maintenance office to fix television, radios, etc. In my free time I used to create electronic projects to sell and I made a few "reais" selling a version of Dancing lights, but it was too limited: it simply animated lamps using a relay in the output of a 4017 CMOS IC. The circuit was a decimal counter  controlled by a 555. 4017 decimal counter. Source in the image When I met Arduino a few years ago, I was skeptical because I said: I can do this with IC, why should I use a microcontroller. I thought that Arduino was for kids. But now my pride is gone and I am having a lot of fun with Arduino :-) The implementation of Dancing Lights with Arduino uses an electret mic to capture the sound and light leds...
