I am Thailand.This project I interest in long time.Now I want to learn this project for my knowledge and using it in my home...in my think it so proud and cool ..I am so sorry in my Eng is not very good to communication...If u see please u gives all detail to me...Thank a lot sir

In video you have taken 7 segment display common cathode but in the link there is common anode which we have to take

[moazelsawaf]

Thanks a lot sir ❤️

This is the first time for me to know that i can program a microcontroller in arduino and use it in a circuit without the arduino....

I liked your watch, but why use the jumper to set the clock time? Thanks

[joeydelmarsjr.]

im working with the chip MSM9004-02, but i dont know what exactly gets
connected to pins labeled as, clock, load, data, and blank.

Давно не заморачиваюсь с подобным. Ардуино и RTC работают в трёх часах и ещё двое wi fi часов на ESP8266.

Try to combine atmega328p with GPS module. You'll be able to make digital clock which doesn't need any setting.

Hi,
I made your watch, but the digits appear confused and unrecognizable, the oscillator is working, the dot is flashing correctly, i cannot find the problem

[jaswanthsaialavalapati]

can you please give circuit diagram for above experiment

[joeydelmarsjr.]

i have a MSM9004-02 in my car that is severed from the stock radio, so it doesnt work. Can i some how make it into a stand alone clock? I have located the pin out of the chip to 10pin connector vcc 5v and LCD voltage, rest, load, clock, and ground. what do i need to make it work independently?

Use an opaque material film to reduce the brightness of the display, it is better to see the hours at night!

[aknulakc]

there is no circuit diagram for Atmeg328p-pu chip to capacitors and crystal

Good work. You literally built a dumbed down arduino uno.

[siddhantsoni]

Brother I need circuit diagram of this pls provide me asap

[brd]

I know electronics this way. If it is 7 segment display, I think in a line of format that in what way can it be lighted or how will it get lighted. This is the way I think. This is simple feasible thinking.

Here You are programing a blank atmel chip with arduino board .Is it possible without flashing the bootloader to the bank chip ?How blank mcu chip supports arduino programming directly ??

[gaithalmohsin]

I need circuit diagram of this project

[mitropoulosilias]

yes but you lose time when replacing battery??

Very good work !!! congratulations by Felipe from Brazil
