Line In vu meter build / update

Download Link : drive.google.c...
The above download includes all vu meters and libraries and android app. Please upload your build version only.
My number one request /comment over the life of this vu meter ( which is about 3 years old) A line in version of the microphone version. This is exactly that.
i have tried to make it as easy as possible. so its not just an upgrade version, its also a complete build video.
You have numerous choices - push button or bluetooth, uno or mega - all are line in., the fix is a direct replacement for the microphone. same level inputs etc.
The parts list is very small, so watch the video to work out exactly the parts you need

Hello, Huge respect to You for the project, time spent and improving. You've helped me a lot with this movie. Big thumb UP from me!!! I admire Your enthusiasm and the amount of work put into this project. Best of luck to You!!

[@cine-lights]

I appreciate that thank you.. this version has been requested so many times it just had to be done. Also the way it's been done opens up a chance of a stereo version.

[@robertjamroz7637]

@@cine-lights the stereo version can be done by combining L and R channels using resistors as far as I can remember about 30 - 47K, but it's probably at a signal with a higher voltage than the one from the headphone port - or use arduino to mix the signal by connecting to the next port - but unfortunately this is not my ability :)

[@cine-lights]

@@robertjamroz7637 basically you would repeat the same connection process for the second channel.. and then add the second channel to each vu meter... it's a lot of code rewriting but will see how it looks first.

Hello, very nice project. But I cannot manage making it work. The 40 leds strip lights up, the button make the patterns change, but it doesn't react with the music. I do not understand the aim of putting 2 résistors between 5V and ground on the pin A5, on 7:37 However, I use the right résistors and the right capacitor. In the sketch you have a pot on pin 4, but I Don't see it on the video. What is its role ? It would be great to add a pot for brightness and another one for the sensivity (so that you can use the volume you want then set the sensivity for a godd response of the vu meter) Can you help me please ?

As i am typing this... i am working on version 2 of the mono, and the stereo version is 95% complete...i cant say anymore..., other than version 2 of the mono vu meter is aiming at 20 vu meters, and 15 standby patterns with alot of control.. and the stereo isnt far off that.

Thank you. I guess its time to fix my thing. I really dont rememer if I put resistors and capacitor into my build like that. Does it fix the gain level or something? Also when I connect my mega to the computer output I get some noise. Bought a galvanic coupler for that, jack version costs like 10 if anyone has problems when using the same output for speakers and VU meter. Also @cine-lights white acryl or glass makes it so much better doesn't it? ;)

[@cine-lights]

Hi Fambaa. my only wish is to be able to share what i see... and my camera doesnt do it... The problem with this build is everyone wanted the microphone as line in... now re-writing the code to accept the new levels using a direct line in like the stereo vu meter would be a headache. so using a few resistors and capacitor to drop the levels to microphone level was easier for everyone. the only code writing was to disable the analogue reference.. which was this " // ".. im working on the stereo version as i write this, some vu patterns do not look good in stereo..... But a little teaser... this vu meter in stereo does look good

[@YouCountSheep]

@@cine-lights Well my version is stereo and you can see it working. I think I had the code from someone else who used yours as base and modified it. He credited you as far as I remember. Idk exactly righ now what was changed. Something on the input I think, but it doesnt solve the problem when you turn up the volume of the line in. Code is still too sensitive. So If you turn down your headphone volume you sometimes see no lights at all and if you crank it up too much the bar VU meters are always full. Thats my issue right now. I have a slight idea how to change it by telling the Arduino to calcuate different values for the inputs I guess. But I havent looked at coding stuff for the better part of a 3/4 year now lol. That was kinda my idea. I mean this lightshow doesnt really need to be a real representation of loudness levels right, just approximate.

[@YouCountSheep]

Oh btw for the kickstarter. Bluetooth for control and sound for line in is definately the way to go. Bc real talk. Microphone will pick up any sound, at parties, for DJs ect. Line in is the convenient thing to do. And shhh. I was planning to build a bluetooth speaker with a fixed power cord, just bluetooth for sound but with VU meter, just a floating idea in my head right now, but what if there is an app that utilizes a bluetooth player control signal to switch to the next pattern ;)

[@cine-lights]

I understand what your saying... my tv has different volume control for headphones and speakers.. my computer i have volume control for the speakers.. so i can adjust speaker out to the leds, and reduce speaker volume .. its looking pretty amazing.. im heading into arduino mega space though.. The added leds for the second channel means less leds for the uno... hmmm... so Arduino uno users i will post a video for the mega... but you have to choose which vu patterns you want on the uno..

[@cine-lights]

The kickstarter vu meter is in process, so will be on sale soon. its based around the arduino uno.., but easily upgradeable.. which means adding bluetooth and line in is easy.. just choose your prefered vu meter and download the code from here... The manufacturer of the That particular vu meter has some amazing things lined up.. one of which arrived in the post today.. so reviews soon

Nice .. is this line in version more sensitive than the msgeq7 breakout board version .... Loving that you always share the code ... There must be thousands of VU meters out there in the wild inspired by you.

[@cine-lights]

The msgeq7 board is a very good board. It separates the channels so you get better sound reaction and choose which frequency you wish the leds to react too. I like the msgeq7 board, but it's hard to find a good one and then its the price. Yes you can make one from a chip. But I try to keep my builds cheap and easy...

It's gonna be with a sound sensor but also with others like temp,light etc. But I'm trying to do with 2 strips one on the inside and one on the outside of the frame. Just tested the justvu code and it works great with the potentiometer still I gotta get the sensor (on their way) and might need a power supply for 90 'pixels' (for now I'm using some phone chargers in parallel) I did see that the chargers make noise soo it's not the system you made.

Hi Steve Yes you will need another Capacitor and 2 resistors of the same value.

Greetings from the UK... The problem i have with quite a few of my projects is i dont keep them.. The vu meter in this video i built only a few days ago and started to use and its the only one i own... so everytime i do an update i have to build another one to use as a test rig. thankfully i have a partial one built already so adding another channel will take 5 minutes. i know some of the vu meters will not look good in stereo, but i will be aiming for about 12 vu meters only to start with so it can be built with an arduino uno and nano to start with.. then in time i will add the standby patterns.

[@stevedimitrakopoulos8923]

[@EGORka140764]

Good Idea and solution. In your scheme, the UNO board is powered by applying a voltage of 5 volts to the VIN contact. But all sources write that the recommended voltage is 7-12 volts. ( The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board..) Will the board not work properly from supplying 5 volts on contact VIN?P.S. Sorry my bad english. :)

[@cine-lights]

Hi Kolobov Igor. On ths setup all we are doing is powering the board so it will run standalone. As the leds are 5v we will use a 5v power supply to power both the board and the leds separately. we are NOT running the leds from the arduino as the arduino outputs a max of 2amps and our leds in this setup requires alot more, attempting it will crash the arduino and possibly damage it. yes you can power the board with the 2.1 dc power jack connector using 7-12v input, which is regulated to 5v but the you would require 2 power supplies so seems pointless. As we are using a regulated 5v power supply which we know is good we can use the Vin pin or any of the other 5v pin on the board to power it.
