Yes that is better. However the 100K resistor seems to have changed to a 220R resistor.This is normally caused by the ground not making contact in the circuit. The arrangement of solderless bread board is notorious for things not actually having the wiring you think you have.This is especially true of the connections to any break out board.
Hi,Welcome to the forum.Have you googled;arduino music light showThere are numerous examples of what you want to do.Tom...
don't see anything at the entrance
What are you looking at, the entrance is not a proper word in this context. What are you using to look at it?
That is not an entrance if anything it is an exit.
I don't think you are getting any signal into your analogue input, measure on the input pin of the Arduino with an oscilloscope to see. But then I don't suppose you have one.
Hi,I notice on your proto board that you do not have jumpers on your red and blue power bus lines.The gap indicates that there is a break in the bus.Have you a DMM to check your circuit voltages.Tom.....
I will connect directly to gnd, just to test xDor would i have to connect anything else to the positive in this scheme? because in fact there's nothing there, so there's no load on the blue bus
the protoboard has many other things connected
Just make sure all your gnds are connected together, it is a current and voltage reference point for ALL your components.Tom... PS, Now is the time for a proper circuit diagram, hand draw a circuit of your project, reverse engineer so you make an exact representation of your project.
That is a classic beginner mistake. You take things one at a time. If you are having trouble with one aspect of your project, then you must build the circuit and write your code so it is only that aspect that is being used.
You are our eyes and hands, without you we can't succeed.
that's why I'm sending you an image of how he was assembling previously
I believe the problem was the capacitor
as I expected, it's less than what I thought the exit would be, but it's still some change,
Thanks for that and the feed back. I noticed the elastic band on the breakout board. If I had to do that I would not rely on the contacts that the bread board makes and solder a wire direct to it and plug the wires into the bread board.
The one on the detector? What exactly was the problem?
This is because the music has to reach 0.7V Peak to peak before the forward voltage of the diode is exceeded. One simply way to improve this is to use a schottky diode in place of the normal one as this type has a lower forward voltage. Or you could use an op amp in an active rectifier circuit to reduce that to zero.Maybe the simplest thing would be to set the A/D converter to use the internal 1.1V voltage reference so you get a bigger range, but that might not discriminate enough. That is produce a reading of 0 or 1023 with little in between.
schottky diode, is the one in the picture good?
op amp is the same as the one in the picture?
active rectifier circuit, I don't know anything,
A / D converter, does the image fit?
Maybe the simplest thing would be to set the A/D converter to use the internal 1.1V voltage reference so you get a bigger range, but that might not discriminate enough.
We don't really need a picture.
If you don't know then the first thing you should do is to put the words into google, it will come up with lots of stuff. Try reading this:-https://en.wikipedia.org/wiki/Precision_rectifier
