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.

In this example the power to the light bulb was on when the timer was counting down and turned off after it finished. Can it also be done so that the power turns on when the timer finishes?

I am looking to use a set up like this to actuate a pull solenoid for a few seconds at a delayed time of 1-60 days

Can someone please help me find the same lcd display like this in the video? I can't find the exact type of display, please help me

[pietrobassoli]

Hi really fantastic prj but could U help me to find a correct LCD I2C U write DISPLAY code for nano and where i can buy it A LOT Piero ITALY

[ankitjain-bvpd]

Kindly use RTC in this project as well

[minaagniabudiani]

Why my lcd screen show the timer 255:255:255, how to repair that

[BrownToiletIsh]

I have a problem, instead of turning off the electricity when I set a timer, it turns on.

[BrownToiletIsh]

Can you please send me the links for the materials

[PeteConstantine]

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?

[franzcastellon]

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...

Do you have a project with a iot solar monitor system

[bubu]

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?

Hello, make a video tutorial for Led Display countdown with Arduino and RTC P10

[niknur]

How to make on delay timer using this method? Do I need to decode or change something else?

[bagaindocgem]

it is possible to set 500 hours countdown? and how?

[toksgagik]

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.

[electroman]

its working. i made it clear. some modification

[benlayshar]

i would like to know how to set the timer for like 1000hours

[soovui]

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.
