Code isn't running

crystxl_satellite · May 9, 2022, 1:49pm

Hello people who are reading this post! I'm sorry if this may be a duplicate but my code doesn't seem to run. I am using Mac book pro 13-inch 2019 with Mac OS Monterey 12.3.1. I am also running this code on the esp8266 and I'm currently trying to make friendship lamps following this tutorial: https://www.instructables.com/CoronaLamps-Simple-Friendship-Lamps-Anyone-Can-Mak/ I downloaded the code on the website and have modified it. It uploads perfectly fine without any errors except that it simply won't run anymore..

Things I've tried to do:

remove all the special symbols
make a simple version
restart application
restart computer
reset the esp8266
eat ice cream
fix the syntax

but it still wouldn't solve the problem. (and I barely know how to code..)

Here is the original code:

//import the libraries
#include <Adafruit_NeoPixel.h>
#include "config.h"

//define the Neopixel pin, this will be different then the pin we soldered the Neopixels to, as they are marked differently
#define PIN 5


//initialize the information for the Neopixels and Adafruit IO
Adafruit_NeoPixel strip = Adafruit_NeoPixel(12, PIN, NEO_GRB + NEO_KHZ800);
AdafruitIO_Feed *lamp = io.feed("lamp");

//how long we want the lamps to stay on when activated (600,000 ms = 10 minutes)
const long interval = 600000;

//setup the timers and status for the lamp
unsigned long previousMillis = 0;
int tap = 0;

//set one of the lamps to 1, the other to 2
int lampVal = 2;

//the value that should activate the lamp. Don't mess with this, the code will figure out what this should be in the setup
int recVal = 0;



void setup() {

  //Start the serial monitor for debugging and status
  Serial.begin(9600);

  //figure out what recieved value should turn on the lamp (lampVal of other lamp)
  if (lampVal == 1) recVal = 2;
  if (lampVal == 2) recVal = 1;
  
  //Activate the Neopixels
  strip.begin();
  strip.setBrightness(255);
  strip.show(); // Initialize all pixels to 'off'

  //setup the touch sensor as a interrupt and input
  pinMode(12, INPUT);
  attachInterrupt(digitalPinToInterrupt(12), touch, CHANGE);
  
  //start connecting to Adafruit IO
  Serial.print("Connecting to Adafruit IO");
  io.connect();

  //get the status of the value in Adafruit IO
  lamp->onMessage(handleMessage);

  //connect to Adafruit IO and play the "spin" Neopixel animation to show it's connecting until and connection is established
  while(io.status() < AIO_CONNECTED) {
    Serial.print(".");
    spin();
    delay(500);
  }

  //when a connection to Adafruit IO is made write the status in the Serial monitor and flash the Neopixels white
  Serial.println();
  Serial.println(io.statusText());
  flash();

  //get the status of our value in Adafruit IO
  lamp->get();
  
  
  previousMillis = millis();
}

void loop() {

  //keeps the ESP8266 connected to Adafruit IO
  io.run();

  //set the starting timer value
  unsigned long currentMillis = millis();

  //tap = 1 means that we have established that the other lamp was tapped
  if (tap == 1) {

    //check to see if the timer if over 10 minutes. If it is, turn off the Neopixels and reset the tap status
    if (currentMillis - previousMillis >= interval) {
      off();
      tap = 0;
    
    } else {

      //if the timer isn't over 10 minutes, continue playing the rainbow animation at a slow speed
      rainbow(200);
      
    }
    
  }
  
}


//the interrupt program that runs when the touch sensor is activated
ICACHE_RAM_ATTR void touch() {

  //while the touch sensor is activated, save the lampVal (either 1 or 2) to the Adafruit IO feed and turn the Neopixels to purple
  while (digitalRead(12) == 1) {

    lamp->save(lampVal);
    
      for(int i=0; i<strip.numPixels(); i++) {
        
      strip.setPixelColor(i, 102, 0, 204);

Changes made:

Modified the code so it would work with 6 lamps
Changed a bit of the colours on the Adafruit Neopixels
Added some more status
Also renamed some of the variables

What happens then? What error occurs when you open the serial monitor?

Maybe ice cream wasn't enough!?

Idahowalker · May 9, 2022, 3:30pm

What problem?

StefanL38 · May 9, 2022, 4:27pm

Well if you modify the code. You have to know what the modification is doing.
The least thing you have to do as your own effort is

posting the original code as a code-section here in the arduino-forum
posting your modificated code
and write a description where in the code you made modifications.

without that additional information you load a lot of unnescessary work on the shoulders of your potential helpers.

Now think about it what descision will your potential helpers make:

to help you
or
to help some other user that follows the forum-rules like described here:

The original code has some problems. In line 66 and line 263 they use "i = i++" in a 'for' loop. That expression produces UNDEFINED behavior and can do anything. Some of the more common correct ways to add 1 to 'i' are:

i = i + 1
i += 1
i++

After fixing the two loops and uploading the sketch to a "D1 mini" clone I got this output on Serial Monitor:

It doesn’t run for me either, so the code and hardware must be ok.

crystxl_satellite · May 13, 2022, 12:10pm

I ate two slices of ice cream cake but it still doesn't work...

StefanL38 · May 13, 2022, 1:17pm

too unserious. No longer tracking this thread

crystxl_satellite · May 14, 2022, 1:30am

The problem that the code won't run
