Completely lost and confused on should be simple project



is this what you were asking for? I used two potentiometers to simulate the joystick cus the exact component isnt available

My guess is that the potentiometers on your print have a joint plus and minus...
Unlike the two single pots in your fritzy.
Add a red wire and a black wire from pot 1 to pot 2 to mimic the copper tracks on your joystick print.

Hi! Welcome to the Forum.

I've simulated your code on Wokwi and it works. So, as @build_1971 suspects, it seems the problem is on the circuit.

Hi im sorry i dont understand where to wire this

Did you have a look on your joystick print?
At the side we cannot see on the picture? (In post #1)?

Your joystick module is uncommon to me. Even Googling "joystick module" images I was unable to find one similar to yours. It has 4 pairs of pins and we need to know which pins are they... (circled in yellow).

I can see 2 GND, 1 VD, 1 UA? What abou the others?

you can take the module out of the breadboard and take a picture of the bottom...

oh ok thank you its like this -

i fixed the GND issue but taking out the GND wire at the bottom right because i dont think i need two and now it doesnt shut off the board. however the circuit still doesn't function correctly now the LEDs dont turn on at all

Connections seemed ok.
L/R+ to VCC
L/R to A0
U/D+ to VCC
U/D to A1
GNDs to GNDs

But this looks odd:

Red and black on the same lane gives a bad feeling...

i took that wire out
you said

L/R+ to VCC
L/R to A0
U/D+ to VCC
U/D to A1
GNDs to GNDs

that is how the wiring is currently set up

struggling to read the schematic so i dont know why its not working

thank you for so much help

still cant locate issue

how can i make it easier to read?

Other things that look odd in the pic of post #1:

  1. Red wire connecting A5 to (+) rail
  2. Not sure what is connected here:

that blue wire is a disconnected error on my end the red wire goes into A3 not A5

This is my second post here as some issues were resolved and i wanted a fresh post for the remaining. I have rebuilt this circuit and rewrote the program multiple times and I cannot figure out what is wrong. I am fairly new to arduino and i am attempting to program this joystick to control four LEDs. I will attach schematics and other visual aids and paste my code here-

`// joystick pins
const int LRpin = A0;
const int UDpin = A1;

// variables for analog readings
int LR;
int UD;

// neutral readings for calibration
int LR_neutral;
int UD_neutral;

// red, yellow, green, blue LED pins
const int Rpin = 11;
const int Ypin = 10;
const int Gpin = 6;
const int Bpin = 9;

// LED brightnesses
int R;
int Y;
int G;
int B;

const int deadzone=10;

void setup() {
  // put your setup code here, to run once:
  // Initialize serial communication
  Serial.begin(9600);

  // get neutral readings for calibration
  // make sure you are not touching the joystick when
  // the program starts!
  LR_neutral = analogRead(LRpin);
  UD_neutral = analogRead(UDpin);
  
}

void loop() {
  // put your main code here, to run repeatedly:
  // read analog pins
  LR = analogRead(LRpin);
Serial.println(LR);

  UD = analogRead(UDpin);
Serial.println(UD);

  if(UD>=UD_neutral+deadzone){ // joystick is up
    B = 0;  // blue LED off
    R = map(UD,UD_neutral,1023,0,255);
  }
  else if(UD<=UD_neutral-deadzone){
    R = 0; // red LED off
    B = map(UD,UD_neutral,0,0,255);
  }
  else{
    R = 0;
    B = 0;
  }

  if(LR>=LR_neutral+deadzone){ // joystick is up
    Y = 0;  // blue LED off
    G = map(LR,LR_neutral,1023,0,255);
  }
  else if(LR<=LR_neutral-deadzone){
    G = 0; // red LED off
    Y = map(LR,LR_neutral,0,0,255);
  }
  else{
    G = 0;
    Y = 0;
  }

  analogWrite(Rpin,R);
  analogWrite(Ypin,Y);
  analogWrite(Bpin,B);
  analogWrite(Gpin,G);
  
}

Can you describe what issues you are seeing?

For these, you might want to take an average and compute the final value before assigning to LR and UD neutral. Try 5 samples and if you want more precision, go for 10.

  • LEDs pins are outputs.

pinMode(Rpin, OUTPUT);
pinMode(Ypin, OUTPUT);
pinMode(Gpin, OUTPUT);
pinMode(Bpin, OUTPUT);
