Abstract

WiFi modul ESP8266 se u ovom radu koristi kao bazna komponenta za povezivanje preostalih komponenti sustava. Mikrofon koji se koristi ima operacijsko pojačalo MAX4466, a platforma upotrijebljena za upravljanje LED trakom WS2812B je Blynk. Sustav radi na način da WiFi modul pokreće instancu lokalnog web servera preko koje se bira WiFi mreža na koju će se modul spojiti radi mogućnosti komunikacije modula i platforme Blynk. Implementirana su 4 efekta LED trake na osnovu rezultata audio signala mikrofona. Odabir efekta i razina svjetline LED trake se postavljaju u Android aplikaciji Blynk platforme.

Abstract (english)

WiFi module ESP8266 is used in this paper as a base component for connecting all other system components. Microphone that is used has operational amplifier MAX4466 and platform for controlling LED strip WS2812B is Blynk. The system works in such a way that WiFi module initiates a local server instance through which we choose the WiFi network to which the module is to be connected for the communication capabilities of the module and the Blynk platform. There are 4 implemented effects for LED strip based on the audio signal readings of the microphone. Selection of an effect and brightness of LED strip is set in the Blynk Android application.
