Sound Reactive Cheap Ir Led Strip

Sound Reactive Cheap Ir Led Strip

well, the idea came after the led strip arrived from AliExpress and they were not neopixels but RGB LED strip with 44krys or 24 key remote types, Dumb me lol, I ordered the wrong one.
I wanted them for a party, but with remote!!! Naaah. So I folded my sleeves and googled it.

Got esp based IR Web server that maps the same remote buttons over the IR emitter pin connected to an IR led.

but I wanted something different like a sound reactive, again i got a lots of Tutorials with ws1811 or neopixels and some even with MOSFETs and LED`s, but i was out of time so i tried a Dumb approach of Mapping Audio though A0 PIn of esp and Mapping the output in buckets to enable some combinations of IR remote Buttons MOstly rgb only but i bet you are going to make it better than me.

1. a LED Strips obviously with Power supply

2. esp8266 / node mcu

3. Ir Emitter led

4. A resistor

5. Programming cable

6. arduino ide

7. a soldering iron (some basic soldering)

8. a 7805 ic (for using led supply as esp supply )

9. A mmicrophone module or aux y split for Sound input

• First of all, connect the Nodemcu with computer or laptop.
• Now install the driver of nodemcu( google it).
• After this open, the Arduino IDE (Of course you need to download it and install it)Click on "Tools" on Arduino toolbar click on "Board" Select "Board Manager" and search for esp8266 install it (will take some time to finish)
• Now, select "Sketch" from Arduino toolbar select "Include Library" from there select "Manage libraries"Search for "IRremoteESP8266" and install it

• Now the configuration is done only from "Tools" we need to go to "Boards" Select "NodeMcu 1.0(ESP 12-E)" or something else version of ESP8266.

• First of all, we need to install irLED library for esp.

GO here

Identifying your led strip either 24 key or 44 key(bigger one ) remote

for getting the remotes code go HERE

With library installed we need to prepare our IR LED by connecting it as shown in Image. Basing on it connect IR LED, then upload the following Sketch and point the IR LED to the controller. The LED strip should blink (turns on and off). // works both with 24 and 44 keys Remote.

HERE is the code to Do so.

#define IR_OFF    0xF740BF  //Resective ir codes in 32 bits<br>#define IR_ON     0xF7C0
#include<IRremoteESP8266.h

IRsend irsend(4); // IR pin

void setup() {
  irsend.begin();
}

void loop() {
  irsend.sendNEC(IR_ON, 32);
  delay(5000);
  irsend.sendNEC(IR_OFF, 32);
  delay(5000);
}

We will use only Analog pin of Espe8266 A0 for Taking Input as Analogue signal and Using it to trigger ir led based on Sound

Connect Out Pin to a0

Connect 5V to Vin (AS node mcu does not have 5v output )

that's it we will align the IR LED connected to D2 pin to the Reciever of LED strip.
