If things still don't work, check the serial monitor to check if there are any back traces. If the ESP32 suddenly does not work, check your power supply.

It is recommended that you use an ESP32 to make sure that you have enough horse power to sample the audio at a high enough frequency and work fast enough to achieve a desirable LED strip frame rate. There is no need to choose the exact same resistors used in this project, I've just used what I had lying around. and also to all the other people that made tutorials online that aided this project.įeel free to modify the code to produce any pattern you like and optimize it to suit your needs. Huge Shoutout to Scott Marley for all the tutorials on Fast LED and Arduino FFT. We are offsetting the virtual ground of the OP AMP so it gets to amplify the full wave To simplify things, we are only using a single supply (assuming most of us do not have a split supply). You can tell when the signal is cut off when the lights are too bright.ģ. Reminder: Do not set the gain too high or the audio signal will be cut off because the of the amplified signal needs to be in the limits of the OP AMP amplification range. Control the gain accordingly to the 'loudness' of the audio signal to make sure that the LED strips are able to react to the audio signal given( They can achieve a gain of about 20) The potentiometers are used to control the gain of the OP AMPs. The left and right audio channels are connected to inverting input of the OP AMPs.Ģ. The value may vary based on the brightness you setġ. It will heat up if you draw too much current from it and might possibly burn out. The AMS 1117 is only meant to regulate 5V to 3.3V for the ESP board. It is recommended that you use an external power supply not the 5V from the Vin pin of the ESP32. Make sure that your 5V power supply can handle at least 2A on most situations, your pc USB power supple should be enough if you don't set the brightness too high. I apologize for providing a hand drawn schematic.
