Started using a ESP8266 from NodeMCU and the specs looked good... until compiling and finding all the RAM is basically used by the system. Wanted to make a web radio that connect to wi-fi and decodes an mp3 stream and plays it. Seems a common gripe that although the specs of the ESP8266 look great... most (CPU/RAM/ROM) is used by the system. (ha... sounds like Windows 10)

Found a great decoder (Helix mp3 decoder) that just needed a minor tweak as it wanted to compile for Windows 32 and not Arduino but found the small amount of RAM it needed used too much as I also had a SSD1322 256*64 4BPP OLED to display the decoded PCM data.

I moved the test to an Arduino Due and it basically blitzed it... even at 84Mhz instead of 160Mhz the decoding is great. Plan B will be using the ESP8266 as intended to just connect and via serial deliver the MP3 stream to the Due.

Was hoping the ESP8266 was going to be a Arduino killer... cheap and great specs. In saying that... it does make the UNO ancient history although the number of spare pins on the ESP8266 are very limiting. The ESP32 may be the solution (getting one this week) as has duel core and I think over 250K available to the user.

The stand-alone MP3 decoder boards go for ~$30+ so if a $6 ESP32 can download and decode MP3 stream, display OLED, output sound it will be a cheap solution. Also... can get small 128*64 1BPP OLED displays from China direct for ~$4.

Hello, because not tests to do the HTML inside the NODEMCU which sends by TX RX to Arduino
This way the communication will be stable and have infinite outputs to control lights

Estimado, buen día, estoy necesitando combinar el led a traves de wifi con un pulsador usando la esp8266, es decir, que el led se pueda encender desde internet o bien desde un pulsador, me podrias ayudar?, muchas gracias.-
