![]() According to the specifications and requirements that were set out, it only failed to meet one and subjectively meets two others. The test consisted of uploading the code onto the board and visually inspecting for the light beam going across the strip. To test if the LED strip was functional, there is an example provided by the Internet that simply propagated a beam through the LED strip. The test consisted of uploading the code onto the board and visually inspecting for the blinking LED. To test if the ESP8266 was functional, there is an example provided by the Internet that simply blinks the on board LED on and off. Once data is available, beats are visualized according to the currently selected Mode. If not, the loop ends and it polls until data becomes available. If successful, the program checks if data is available from the server. ![]() Inside the main loop, the first thing it does is check whether the Wi-Fi client successfully established a connection with the server. An initial setup function is run only once and it initializes the Blynk app connection, the client, and the LED strip. The system cannot be tethered to a PC or a power socket and needs to be convenient to place around a house.įigure 12 below is the firmware flowchart for the ESP8266. The system needs to run until it is turned off by the user. The project also requires the use of Blynk, a platform on iOS and Android that is used to control devices, in this case the ESP8266, over the Internet. There are four different visualization modes and some have the ability to be customized in terms of speed and color. Because it reacts to audio in general, there is no limit to the number of songs it supports. The project works with any audio but really only makes sense with music. The audio signal processing must be done by the Processing app using the Minim library and the Fast Fourier Transform (FFT) within it. The ESP8266 and the PC running the Processing app must be on the same network. There is a logic level shifter between the ESP8266 and the LED strip because the former is 3.3V device and the latter is a 5V device. The ESP8266 communicates with the LED strip via SPI with only the SDO (data) and SCK (clock) lines. Thus, the LEDs will take the value and give out the color and the intensity of the light accordingly.The project needs to have an LED strip react to audio in real-time and over Wi-Fi. The sound sensor senses the frequency of the sound and sends the data to the serial monitor. As soon as you play the music, via any media. The sound sensor is to be kept near the speakers may be your laptop or your home theater. Upload the following Arduino Code to evive. Make sure to connect the RGB Strips in parallel. Glue the paper upon the semicircle using hot glue. Take a sheet of butter paper and fold it in half. Cut the butter paper of the length equal to the diameter of the circle. We are going to use butter paper for the same. Now we need to cover the LED strips so that the light from the LED can disperse. Glue it on the rectangle using hot glue and make small holes in the bottom sphere. ![]() Now take two RGB Strip of the length of the rectangle. Similar glue the other one to the bottom edge. ![]() Take one of the semicircles and glue it on the top edge of the rectangle using Hot glue. Once you have the circle or the sphere, cut it from the center so that you can get two equal semicircles. Upon this, we will be mounting our RGB strips.Ĭut a sphere of the diameter same as the width of the rectangle. Take the cutout of a rectangle using the cardboard sheet. Using the concept of sound reactive RGB Lamp, we are going to make LED lamp that will change the color and the intensity of the light according to the music. ![]()
