Code not working as expected,

[amitf]

here is a sketch
hope this work. i haven't tested it

#include "RTClib.h"

RTC_DS1307 rtc;
const int StartTime = 9;
const int refresh = 30; // time in minute to change brigtness
const int steps = 4; // increaserease or decreaserease every half hour by 3 step
int TotalMin;
int currentHour;
int currentMinutes;
int increase;

int j [3] = {9, 10, 11}; //rgb led pins red D9, green D10 , blue D11

void setup () {
  for (int i : j) {
    pinMode(i, OUTPUT);  // setup ur rgb led pin
    analogWrite(i, 255); // turn on lights one by one
    delay (500);
    analogWrite(i, 0); // and turn off after half second delay (comment out if you dont like it )
  }
  Serial.begin(115200);
  if (! rtc.begin()) {
    Serial.println("Couldn't find RTC"); // will print
    Serial.flush();
    abort();
  }
}

void loop () {

  DateTime now = rtc.now();

  currentHour = now.hour(); // storing hours
  currentMinutes = now.minute(); //minutes
  TotalMin = (currentHour * 60) + currentMinutes; //total minutes

  int decrease = ((((TotalMin - (StartTime * 60)) / refresh) * steps) - 70) * (-1); // justa a formula to decrease the value
  increase = ((TotalMin - (StartTime * 60)) / refresh) * steps;
  if (currentHour >= 9 && currentHour <= 17) {
    analogWrite(9, 255);
    analogWrite(10, 100);
    if (currentHour >= 9 && currentHour <= 13) {
      analogWrite(11, increase);
    }
    if (currentHour >= 14 && currentHour <= 17) {
      analogWrite(11, decrease);
    }

  }
  else {
    for (int i : j) {
      analogWrite(i, 0);

    }


  }

  delay(60000); // 1 minute delay
}

to understand the code properly you only need a little knowledge of for loop, if-else, operators and variables

[amitf]

also it will look more beautiful if green also fade in evening which will give a reddish look

like this

[amitf]

you need to set the time to RTC before uploading this code

[arshath786]

Thank you everyone. Managed to solve it.

[arshath786]

Hi Stefan, your code worked for me. However, I now have troubles integrating the RTC into my circuit. Here's the information I have.

1. On one Arduino board, the code worked flawlessly. The port COM5 was in use. But on the arduino board inside my lamp, when I connected my laptop to it, it said COM5 had an error connecting to it and only COM7 worked. But I had not changed the USB port I used on my laptop.

2. On the board inside my lamp, when I tried to get an RTC reading, it started going haywire and printing out random characters and dates. The date was stuck at 165/25/165. I used the exact code you have me in the solution I have marked. Can I know what is wrong with my situation? I am also pretty sure the circuitry is correct.

Pictures for your reference.

Much appreciated.

[StefanL38]

changing the comport between connected devcis is very normal. The comport number does not depend in the USB-port. It depends on some internal device-ID of the USB-to-TTL-chip

The fact that your serial monitor shows the correct characters like "Current Daten & Time" and sometimes strange characters is a hint on bad signal quality. Or a may a slightly uncorrect baudrate.

You are using a breadboard inside your lamp. Breadboards are for prototyping but not for longterm use. It might be that there is bad contact somewhere. That would explain the wrong numbers in time and date. I2C is the abbreviation for intercircuit-circuit-communication.
I2C was developed to interchange data on short distances across PCB-tracks If normal wires are too long the signals gets too much bended and the communication no longer works.

But sometimes correct characters, sometime bad characters on the serial monitor?

In your lamp are you using arduino IO-ins 0 and IO-pin 1 for anything?
These are the two IO-pins that are used for the serial communication.
You should keep away anything else from IO-pins 0 and 1.
Keep IO-pins 0,1 free.

What kind of a lamp ist this? What voltage ? what current?

If you look at the baudrate of the serial monitor what is it adjusted to?

If you look at the baurate inside of exact that code that you have really uploaded into the Lamp-Arduino what is written there?

void setup() {
  Serial.begin(9600);
  delay(3000); // wait for console opening

What is shown in the serial monitor if you upload a very simple code that does nothing more than just printing "Hello World" to the serial monitor?

[arshath786]

Hi @StefanL38 , here is some information for your analysis.
The baud rate (9600, no line ending) is correct, I have triple checked. The lamp operates from a 12V power source, and the circuit is managed by transistors. Below is the circuit diagram.

The circuit by itself works well, when I used the delay function. In this case, I have not yet integrated the RTC with the circuit. I just connected the RTC to the breadboard and Arduino board, separately from the circuitry of the lamp. I just wanted to see if the RTC functions with this Arduino board too, but as you know, the strange characters showed up. Pins 1 and 0 are kept free. When I tried to print "Hello World," the system replies that "serial does not type a name". When I tried to input the code you gave me for the RTC, it says "the selected serial port does not exist, and you're board is not connected,".

Hope you can sort through this for me, thank you.

[anon57585045]

@arshath786

the system replies that "serial does not type a name"

Did you mean, "Serial does not name a type"?

This is why we request that you copy and paste the entire message instead of paraphrasing it.

[arshath786]

Yes my bad, sorry

[StefanL38]

person: calling a doctor on the phone "doctor make me feel good again"

doctor: what kind of problems do you have?

person: I feel pains

doctor: where do you feel pain

person below

doctor below what?

Do you get it? From this poor information it is impossible to really help.

@arshath786

When I tried to input the code you gave me for the RTC, it says "the selected serial port does not exist, and you're board is not connected,".

You seem to have difficulties withe connecting your board.

Now your information is not that poor but your posting is still missing important information

If you get a compiler-error provide all details for analysing the error

Hi newcomer, the Arduino-Forum community can be of great help. If the community is able to support you in a way that helps solving your problems depends on detailed information that you should provide. trying to be quick by posting a too short posting is just slowing down finding the solution. Because all that happends is that you are asked for the detailed information and have to provide it anyway. Only difference the answer and the solution comes later The most important thing is to pos…

[arshath786]

Really sorry about that Stefan.

Here's the error code.

you shouldn't use a onedrive drive you should use a local non-onedrive-drive

         AVR Part                      : ATmega2560

Your arduino-IDE seems to be adjusted for arduino Mega 2560
your pcitures show a Arduino Uno which is a diffent board and must be chosen as the board

But I'm not really sure I can't see it from your picture.

All in all the lines you have posted as a whole don't make sense to me

please do the following

• close the arduino-IDE
  -reopen the Arduino-IDE

load one single sketch
click compile and upload

and if the compiling/uploading-process aborts

immidiately

click copy error-messages
then post this logfile as a code-section

A successful upload to Arduino Mega 2560 looks like this

I supsect a bad USB-cable or insufficient power-supply.

You are using 100 Ohm resistors as base-resistors
This is a pretty low value
5V / 100 Ohm = 0,05A = 50 mA
An IO-pin can draw a maximum of 40 mA. And you should stay below 20 mA if ever possible.

A base-current of 10 mA should be plenty enough to drive your LEDs
Though this must be checked inside the datasheet

10mA means: 5V = 0,010A = 500 Ohm.

@StefanL38 The problem is not the Lamp circuit, because it works fine by its own. I'm separating the circuitry of the lamp and the RTC, and I just tested the RTC by itself to see if it functions. This time when I tried what you said, there was no error stated, but there were many red lines in the messages. Sorry to keep troubling you.

If the log finishes with

avrdude done.  Thank you.

the upload is OK.
So what is your serial monitor showing?

[arshath786]

The same garble. I don't know what to do....

[StefanL38]

unprecise information

post the output to the serial monitor as a code-section

did you try a different USB-cable?
did you try a different computer?
did you try re-booting your computer?
