Working on a project with 2 potentiometers 2 push buttons 2 LEDs and 1 buzzer

fishbulb0 · June 8, 2025, 7:26pm

I'm running into trouble with this. The general idea is to have one potentiometer select the color for the LEDs and a button to light them and then the other potentiometer to select the tone for the buzzer and the other button to sound the buzzer. When I tested these separately they worked fine but when combined in the same program it seems the buzzer doesn't respond properly. I've read that this might be down to threads or the board simply only being able to respond to one input at a time. Someone suggested that I implement "interrupts" to solve the issue but I'm not sure how. Anyway, its a relatively simple program and I'm still pretty new to this platform. I don't consider myself a coder so much as an artist that's interested in programming and electronics. You can review my code here: Arduino code for 2 LEDs 2 buttons 2 potentiometers & 1 buzzer - Pastebin.com

Any advice would be greatly appreciated! Thanks!

Please, move your code from the link to this page (so the code will stay after your link goes away).

LEDs (RGB or WS2812) use combinations of red, green and blue light to create color. One potentiometer would not allow for adjusting all three colors.

Same issue with WS2812. How do you use one potentiometer to represent three colors?

xfpd · June 8, 2025, 7:59pm

Using delay() interferes with (blocks) other code. For your code to read the potentiometer while playing a tone, delay() must be eliminated, allowing the program to flow without stopping (on delay()).

sonofcy · June 8, 2025, 8:04pm

Look up button bounce and maybe use a library for that.

fishbulb0 · June 8, 2025, 11:03pm

could this be solved by replacing the delay() function with millis()?

dougp · June 9, 2025, 12:01am

Isn't this the same as:

if(percent2 == 3) ?

qubits-us · June 9, 2025, 12:31am

@fishbulb0 ,

bored, removed all use of delay for you..

Your project simmed..

good luck.. ~q

I appreciate your effort but that did not work lol

xfpd · June 9, 2025, 3:10am

It "worked" for me. Describe your observations.

@fishbulb0
Didn't you bored to enter this almost same block 100 times?

I recommend you to read something about arrays - then you can able to replace them all by 5-10 lines of code.

qubits-us · June 9, 2025, 12:14pm

seemed to work for me..
care to elaborate??

alto777 · June 9, 2025, 12:56pm

Who said that and how much did she know about your project and your problem?

Just curious.

Claudio_FF · June 9, 2025, 1:20pm

And did he also tell you what other (concurrency) issues arise when using interrupts? Leave interrupts as a last resort, and only use them to handle truly fast asynchronous signals.

I'm working on a simple program that uses 2 potentiometers, 2 push buttons, 2 RGB LEDs, and 1 buzzer. The basic idea is to use 1 potentiometer and 1 button to select the color to display on the LEDs and the other potentiometer and button to select the tone to sound the buzzer. Here is my code let me know what you think is going wrong:

#include <SPI.h>
#include <Wire.h>
#include <Adafruit_NeoPixel.h> // include the Neopixel Library in this Sketch
#include <ezButton.h>

#define PIN2 5 // This is the Arduino Pin controlling the other LED pixel.
#define POTENTIOMETER_PIN A0
#define POTENTIOMETER_PIN2 A2
#define BUZZER_PIN 11 


//This sketch is to make a potentiometer position determine a color of a LED
// that shows when a button is pressed

//If possible, another potentiometer to determine tone

#define NUMPIXELS 1
#define BRIGHTNESS 50
Adafruit_NeoPixel pxl = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRBW + NEO_KHZ800);
Adafruit_NeoPixel pxl2 = Adafruit_NeoPixel(NUMPIXELS, PIN2, NEO_GRBW + NEO_KHZ800);
ezButton button1(7);  // create ezButton object that attach to pin 7;
ezButton button2(9);  // create ezButton object that attach to pin 9;

Since there's no processor difference that would matter based on your code, I think you're wrong. However, without a schematic, we can't tell if you're overloading the 5V pin on the Nano, which is certainly more likely with a Nano than an Uno. So show us how things are wired, please.

fishbulb0 · June 10, 2025, 6:45pm

I'm not great with schematics. I have the two RGB LEDs connected to the 3 and 5 digital pins with 470 ohm resistors. The two potentiometers connected to the A0 and A2 pins. The two buttons connected to the 7 and 9 digital pins. The buzzer is connected to the digital 11 pin. I have a 1000uf capacitor connected to the 5V and ground pins and wires running from those to the positive and negative rails of the breadboard. Finally, I have a 9 volt battery connected to the ground rail and a slide switch which runs to the voltage-in pin.

Brazilino · June 10, 2025, 6:54pm

This is a poor choice, because 9V batteries are quickly drained.

The Uno and the Nano are almost the same board in different clothes. My first shot would be: the battery was good before and now it's not anymore. Why don't you try 5 or 6 AA batteries instead?

fishbulb0 · June 10, 2025, 7:04pm

Solid advice I will take into consideration. However, something else I feel could be relevant: this is a new version of the Nano I haven't used before and I noticed some peculiarities. Most obviously, the port it uses is a USB-C. Second, when I try to upload my project to the board it's unable to when I set it to recognize it as an Arduino Nano but it uploads when I set it to recognize it as an Arduino Uno. It seems a little fishy
