Hello! I'm a beginner in arduino and I really tried my best to do it on my own, but I'm running out of my own wits so I really need to ask for help now.
So basically my project is to build a lamp that changes its color depending on the time. So I made it rtc-controlled. I think I may be having code problems, or missed out connections but I am not sure where. I really don't know where I made a mistake so I am now asking. This is currently my breadboard and my code.
It would really mean a lot for me to get help in this. Thank you in advance and I truly appreciate it.
I am using Arduino Uno, a couple of N-type MOSFETS, a 12V LED strip, and a DS3231 RTC.
#include <Wire.h>
#include "RTClib.h"
RTC_DS3231 rtc;
#define REDPIN 5
#define GREENPIN 6
#define BLUEPIN 3
#define FADESPEED 50
void setup()
{
pinMode(REDPIN, OUTPUT);
pinMode(GREENPIN, OUTPUT);
pinMode(BLUEPIN, OUTPUT);
Serial.begin(9600);
Wire.begin();
rtc.begin();
if (! rtc.begin())
{
Serial.println("RTC is NOT running!");
}
pinMode(8, OUTPUT);
}
void loop()
{
int r, g, b;
DateTime now = rtc.now();
Serial.print(now.year(), DEC);
Serial.print("/");
Serial.print(now.month(), DEC);
Serial.print("/");
Serial.print(now.day(), DEC);
Serial.print(" (");
Serial.print(now.hour(), DEC);
Serial.print(":");
Serial.print(now.minute(), DEC);
Serial.print(":");
Serial.print(now.second(), DEC);
Serial.print(")");
Serial.println();
Serial.println();
delay(1000);
//lights code
//blue light
if (now.hour() == 05 & now.minute() == 0 & now.second() == 0)
{
for (r = 0; r < 256; r++) {
analogWrite(REDPIN, r);
delay(FADESPEED);}
}
else if (now.hour() == 18 & now.minute() == 0 & now.second() == 0)
{
for (r = 0; r < 256; r++) {
analogWrite(REDPIN, r);
delay(FADESPEED);
}}
// golden light
else if (now.hour() == 06 & now.minute() == 45 & now.second() == 0)
{
for (b = 255; b > 0; b--) {
analogWrite(BLUEPIN, b);
delay(FADESPEED);
}
}
else if (now.hour() == 17 & now.minute() == 45 & now.second() == 0)
{
for (b = 255; b > 0; b--) {
analogWrite(BLUEPIN, b);
delay(FADESPEED);
}
}
//midday light
else if (now.hour() == 8 & now.minute() == 0 & now.second() == 0)
{
for (g = 0; g < 256; g++) {
analogWrite(GREENPIN, g);
delay(FADESPEED);
}}
//cloudy light
else if (now.hour() == 15 & now.minute() == 0 & now.second() == 0)
{
for (r = 255; r > 0; r--) {
analogWrite(REDPIN, r);
delay(FADESPEED);
}}
}
