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

Video quality much better this time👍👍

Superb work sir

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.

Big Fan Dada❤❤🔥Want to Meet with you...

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.

Thx!! you saved my life //from korea

Nice project 👍👍

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

Nice project

Hi, could you add the auto reset at the end of the time. Thank you

Super brother

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.

Do you have a project with a iot solar monitor system

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

Where's the complete code

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?

For god sake give me the code i really need that
