Hey, thanks for sharing this project! Works great altough I think as you've described in response for another comment the sensitivity would be better without I2C but with I2C it works fine for me. One thing I noticed is that the spectrum goes to around 9 kHz and that's it. Would it be possible to make the spectrum to go as far as 16 kHz? If so, what changes would be necessary. Thanks!
Thank you for your effort! It’s not really a big deal because in essence it works well, it’s just a detail. But also when I was working on the project today I noticed that the visualization stops working when I try to declare a variable for storing potentiometer data using the analogRead() function. According to your schematic I used the A0 pin for the Jack connector so the potentiometers use pins A1, A2 and A3. But when used all I get is the bottom row of the spectrum and a periodical wave of pixels that turn on and off and that’s basically it. Once analogRead() for the potentiometers is removed everything works fine again. Btw, the potentiometers are for adjusting volume and EQ and the values are displayed on an LCD.
i constructed two pieces but they didnt work wirng was according to circuit diagram. included libs also uploaded the code it uploads successfully but dont wok just one static line shows up, is there any change in ciruit diagram
I'd like to do a 10-band spectrum analyzer using 10 strips of individually addressable led strips as the output rather than the lcd display. Could this be adapted for that?
in demo clip you have shows LCD all pins soldered while in circuit diagram data pics nor used D0 D1 D2 D3 not used id lcd. can it be difference of NAANO and NAN0 V3.0? i have simple nano with atmel 328p and it uploads on new bootlogger doesnt work on oldbootlogger please help
Hi Hazi, I've built your system but all i'm getting on my lcd screen is the top row of characters are completely filled out, and the bottom row does not show at all. Have you had this before? I've made 2 input units ( the 3 resistors and the cap) and i've used 2 different lcd screens. I'm using this arduino nano : "Nano 3.0 Atmega328 5V 16 MHz " I have tried it on my genuine Arduino uno, same result. Also, when i println my A0 to the serial monitor, i only get the value 14. nothing else. I fixed it by altering the code so there is no need for a button and wired rw to ground. Also removed the potmeter and used a digital out instead. Works great.
Hello, i see you've used an lcd display for the job, would it be possible to use a 0.96 inch oled display ( 7 pin ) in the 4SPI mode ?if so which pins should i connect ? ( ive got GND, VCC , D0 , D1 , RES , DC and CS )
Hi Hazi Tech, I really like your projects and I build most of them. They work great. I am trying to do a Charity project for my local archery club where I design an adjustable countdown timer with audible sound and I am stuck with the design and I was wondering if you can help me out as you are an expert with Arduino. The countdown clock must be able to set what ever time is program with audible notification. eg. if I set the time for 4 minutes and 10 seconds, I push a button to start, a single audio signal blast and after the 10 seconds there is 2 audio blast and a green light turns on. While the time is counting down and it reaches 30 seconds remaining, a amber light comes on and at the end of the 4 minutes time a 3 audio sound blast and a red light comes on. Then the operator needs to repeat the time again
@@HAZITECH this is ok pls we can try bass trable and volume with lcd screen u like audio technology/music? and correct equalizer spactrem on big display
