Bar Graph

Yeah, I was afraid it might be kind of daunting. Interrupts are sort of a "level 3" topic.

You may be able to fudge something in the interim. For example, you might add an extra equivalent pause to each delay() call, or you might do the screen refresh on each step of the LEDs. This isn't optimal (the maximum blink speed will be much slower), but the timing will be more consistent.

OK I'll try those options and see how it goes thank you for your help

OK i think i got it going so far. I had to put a delay of 400 in every LED cluster and remove the very last sensor delay. They are scrolling alot slower but it does work.

Code: Select all

#define OLED_DC 11
    #define OLED_CS 12
    #define OLED_CLK 10
    #define OLED_MOSI 9
    #define OLED_RESET 13

    #include <Wire.h>
    #include <Adafruit_GFX.h>
    #include <Adafruit_SSD1306.h>

    Adafruit_SSD1306 display(OLED_MOSI, OLED_CLK, OLED_DC, OLED_RESET, OLED_CS);

    int sensorPin = A0; // select the input pin for the potentiometer
    //int ledPin = 13; // select the pin for the LED
    int sensorValue = 0; // variable to store the value coming from the sensor



    void setup(){

    display.begin(SSD1306_SWITCHCAPVCC);
      // init done
     
      display.display(); // show splashscreen
      delay(10);
      display.clearDisplay();   // clears the screen and buffer
      delay(10);
     
      display.setTextSize(5);
      display.setTextColor(WHITE);
      display.println("KITT");
      display.display();
      delay(10);
     


       pinMode(6, OUTPUT);
       pinMode(5, OUTPUT);
       pinMode(4, OUTPUT);
       pinMode(3, OUTPUT);
       pinMode(2, OUTPUT);
       pinMode(1, OUTPUT);
       pinMode(0, OUTPUT);

    }


    void loop()
    {
              // Read analog input:
    sensorValue = analogRead(sensorPin);
    // Scale input to width of display:
    int w = map(sensorValue, 0, 1023, 0, display.width());
       // Draw filled part of bar starting from left of screen:
    display.fillRect(0, 0, w, display.height(), 1);
       // Erase the area to the right of the bar:
    display.fillRect(w, 0, display.width() - w, display.height(), 0);
    // Update the screen:
    display.display();



       sensorValue = analogRead(sensorPin);
       digitalWrite(3, LOW);
       digitalWrite(4, HIGH);
       digitalWrite(2, HIGH);
       delay(sensorValue);
       delay(400);
       sensorValue = analogRead(sensorPin);
       digitalWrite(4, LOW);
       digitalWrite(2, LOW);
       digitalWrite(5, HIGH);
       digitalWrite(1, HIGH);
       delay(sensorValue);
       delay(400);
       sensorValue = analogRead(sensorPin);
       digitalWrite(5, LOW);
       digitalWrite(1, LOW);
       digitalWrite(6, HIGH);
       digitalWrite(0, HIGH);
       delay(sensorValue);
       delay(400);
       sensorValue = analogRead(sensorPin);
       digitalWrite(6, LOW);
       digitalWrite(0, LOW);
       digitalWrite(1, HIGH);
       digitalWrite(5, HIGH);
       delay(sensorValue);
       delay(400);
       sensorValue = analogRead(sensorPin);
       digitalWrite(1, LOW);
       digitalWrite(5, LOW);
       digitalWrite(2, HIGH);
       digitalWrite(4, HIGH);
       delay(sensorValue);
       delay(400);
       sensorValue = analogRead(sensorPin);
       digitalWrite(2, LOW);
