Just wanted to chime in and let you know that this is excellent. I had something set up with an amazon relay/timer that 'worked', but the shortcoming was that once tripped, it would just count down to zero and stop, even if the trigger was re-tripped, which was a problem. This worked perfectly, and when tripped, it turns on and counts down, but if re-tripped, it resets the timer, so if it keeps getting re-tripped, it keeps resetting and will only finish the countdown and stop when it's no longer being tripped, which is exactly what I needed.
You deserve love and appreciation
Great tutorial. Learned a lot. I’m curious though, does the power for the lightbulb also power the Arduino? If it does, how does it back feed through the relay?
Hello, thank you very much for sharing your knowledge. I would like to know if it is necessary to include some resistors, to protect the circuit.
Hi, could you add the auto reset at the end of the time.
Thank you
Video quality much better this time👍👍
What simulator did you use sir?
Thanks a lot for sharing,r u able to make a another video teaching us by adding in a features a delay trigger mode in second, min and hours too.
One question , How are you powering the arduino nano?
Hi can I add push botton switches to power te lights
Do you have a project with a iot solar monitor system
Can I do this with 12v current? I need this to shut off and on my refrigerator compressor every 15minutes and the current passing through to the relay is 12v
Thank You So Much 💓
its is possible to add Bluetooth on this project of your? and how to code it?
Can I use this circuit without the relay module?
how do I code if I use 0.91' oled i2c display instead of LiquidCrystal I2c?
after pressing the button I can't set anything... can you help me with this? and the question is whether 12V can also be connected to this relay?
Kindly use RTC in this project as well
its working. i made it clear. some modification
Where does the electricty comes from?
Hi, can we use the timer for multiple LED or Relay?
can you please tell how EEPROM han help in this, I am trying to make an Inching project where relay switch turns off after an unchangeable coded timer and it may not reset as the power to micro controller cuts off accidentally.
Hi, how to prevent the time goes to negative number? my test got 0-1 hour after seconds got 0 . Thanks.
Can you please make driver drowsiness detection system using raspberry pi and usb camera
Hi really fantastic prj but could U help me to find a correct LCD I2C ......could U write DISPLAY code for nano and where i can buy it .........THX A LOT Piero ITALY
Hello would you share your gerber file to order in jlcpcb and assemble your components for this project? Thank you and good job!

Nice project
Bro pls make A arduino volume bass controller with effects...
Beautifull and usefull !
Bonjour j’aimerais avoir le programme du projet
i would like to know how to set the timer for like 1000hours
What software were you using to design the circuit? Does that allow you to run simulations?
Bro i also want to know about that.
Have you gotten some info
Please let me know when you do so :)

I can't find a code. Can you help me?
how this looping ?
Hello bro
Bro the screen is showing blocks
Great video! I was wondering, I have a spare OLED (128x32, SSD1306) screen, would it be possible to use it as well? I know the code will change but, can you do it? Thank you so much!
same problem, have you done it already ?
impressive
Can you please give me the library Countimer.h
where the code for the timer works, I do not have anything showing on the LCD. any thought where to look for my error? The LCD Pot seems to adjust contrast as well. since i am newer, i may be missing something obvious.
yes me too
Me too
Yes I have same issue
Can i make this project using esp8266
bro why i cannot download your code,
what is the name of the simulator
Nice project 👍👍
Cant download the code help me pls.
Bro with servo motor please...... 😢
sir small help is need
The first time I tried this worked perfectly, but the next day I tried with both my UNO and UNO R3 and the timer initializes to 254:254:254 instead of 00:00:00. I do not even know where to begin diagnosing this problem. Please help!
I had problem on lcd can't display can you help me
Do we have to set time again and again in this project
All vdo related this topic are same, please change if you can
I want timer on side and off side both
Suppose
10 second on (manual set)
30 minutes off (manual set)
Again 10sec on 30 minutes off
This process continues run until manual switch off.
I have a problem, instead of turning off the electricity when I set a timer, it turns on.
I actually wanted turn on timer
Can you send what you have done
Where's the complete code

@@Mahi.333 hey it's better if you use chat gpt. I waited for so long. No reply
جميل
Super brother
it is possible to set 500 hours countdown? and how?
ya i would like to know how to set the timer for longer
ya same i would like to know if you can set for like 30days
ya man same here i know is possible i just dont know how to do it i hope he make a how to video
My 16x2 display don't have sda scl converter circuit connected that is connected in your lcd, plz make this circuit with this same 16x2 lcd without sda scl wires,
Buy an I2c module
@@anokhautomation4453 i know that😅 but by modifying the code it will also work.
Replace the I2c library with the regular liquidcrystal library and initialize the pin numbers, code will be the same
@@ViralScience That's the answer i was watin for, Thanx👍
@@ViralScience عندي الشاشة 2*16 مع المحول ولكن لا لا ويظهر شيء اين المشكله . شكرا لتعاونك معنا مقدما
@ViralScience I have the screen 2 * 16 with the adapter, but nothing appears, where is the problem? Thanks for your cooperation in advance
Can i have the code please?
Lcd .begin (); error , how to solve
same problem here
Subpar bro
Good
HelloViral Science can you help me with a software-related matter? I want to create a project. In my project, I will be using a Nextion TFT screen, Arduino Uno, Green LED, Blue LED, DC motor driver, and DC motor components. In addition, I will use one yellow button and one red button.
The program's operation is as follows:
I will input a value, such as 5000 milliseconds, into the "n0" object on the Nextion screen. I will also enter a value between 0 and 255 into the "n1" object, which will be related to the motor's speed. Based on these values, the motor will run between 0 and 255 revolutions for 5000 milliseconds and then stop. After entering these values, to start the program, the "b0" object on the Nextion screen and the Arduino, connected to the analog "pin1" yellow button, will serve the same function. Whenever the analog "pin1" button or "b0" object is pressed, the motor will start running again and stop when pressed again. In case of an emergency while the motor is running, there will be a red button connected to analog "pin2" to stop the motor. When the "pin2" button is pressed, the running program will stop immediately, and the green LED will turn off. To restart the program, we will need to press the "Dual State Button" button. All of this system will be controlled by the "dual state button" object on the Nextion screen. When the dual-state button is open, the system will be ready to run, and the position of the dual-state button will be indicated by the green LED connected to digital "pin 12". I want to create a project that operates in this way. What is the cost of such a project?
hello good day
hi Viral Science HOW can you set the timer for like 700 hours or longer please make a vid on how to set the timer for longer my brother
yes viral science how do you set the time for more then 99hours ?
Do some maths. Like one way to brute force it is to create a variable called totalReached. So like, when you count to the max a variable can in milliseconds, you record that, and do :
unsigned long totalReached = 0;
totalReached = totalReached + 1;
And when you want to check for 90 years, lets say max timer is 24h,
If (time == *max value in milliseconds* && totalReached == (90years*365days/years) {
cookMeASandwich;
}
Idk something like that
For god sake give me the code i really need that
This is the only video on TH-cam about arduino without code. I guess you don't want to share it
i got the code and schematics,
i think you forgot to wear your glasses or u can't hear properly.😅😅
As he already mentioned how to get the code, library and schematics of this project.
can someone please help me. I'm trying to make a feeder for my rabbits and need to feed them every 8 hours. I'm trying to come up with something that will go on for few seconds then stops then goes on again after 8 hours and so on. Please help me. Thank you so much!
I will sell it in my country. 😊
THIS IS NOT WORKING, DONT BE FOOLED BY OTHER COMMENTS.
Noice.Dont pin this
lol u hearted
