It is recommended to get a logic level converter for dealing with the conversion between 3.3V and 5V. Theoretically, because the ESP8266 module pins are 3.3V and the data-in wire is 5V. I wrapped resistor around the data-in wire. Connect your set 2's ground wire to the ground of the ESP8266. Take your 1000 uF capacitor and connect it across both terminals.Ĭonnect your set 2's data-in wire to a 470 Ohmn resistor and continue to connect to the RX pin on your ESP8266. The wires on the other direction are for connecting to other strips.Ĭonnect your set 1's power wire to the positive terminal of your power supply's terminal connector and connect set 1's ground wire to the negative terminal. The red means power, black/white means ground, and green means data-in.set 2: 1 red, 1 black/white, and 1 green.It might take some time for you to wiggle it into the breadboard.įind the wires of the strip with the white arrow pointing away from you. Hardware Setupįlush your ESP8266 onto the breadboard. To cut a led strip you want to cut following the white vertical line between the 3 rows of orange-looking thingy. So to make this work, I cut my 5 meter strip into a 4 meter strip, so I only needed 72W (18*4), which will work with my power supply. However, I only had a 5V power supply rated at 15A, which can only support 75W (5*15). Using the power law, P = IV, this means I needed 90W (18*5) from my power supply. In order to provide enough power, the 5V power supply has to be able to support a minimum current (amps).įor example, I had a 5 meter strip that had a power rating of 18W/meter (you can find this information on the back of your led strip package). It is very important to match the length of your LED strip with the right 5V power supply because the longer your strip, the more power it requires.

#Reactive audio visualizer software serial
I'd only recommend serial for really simple visualization. You can use serial instead of wifi for this project, but the read and write speed of serial connection via USB is too slow to visualize this project. For example, an plain Arudino Uno will not work because it does not have wifi support. You can probably replace the ESP8266 with other compatible module that has wifi support. We are going to be using Python to send UDP packets to our ESP8266 module. I used a 15A and it came with a terminal connector (read below regarding current) I used 4 meters (read below regarding length)

Unfortunately, Devon's DIY involved a frequency to voltage circuit that I had no idea how to build, so I decided to use an open source project, audio-reactive-led-strip, which essentially replaced the frequency to voltage circuit with a out-of-the-box Python code. So today I decided to f*ck it, let's do it. I remembered watching his DIY LED Music Visualizer | Real-Time Animations and wished that I could also do it myself.
