Thank you. I did this project in minutes and now the clock is running ok in my bedroom. Make sure you placed all the library files in the right place before compiling/uploading the code. It's better to adjust the brightness using the code:
P.intensity(0);
for the brightness; because the LED will be too bright for our eyes.

In France, we changed time and switched to winter time for that I have to reprogram my ESPIs there a way to automatically switchthank you for your reply

hello from france

hi, may I know, how many times this clock connects with the NTP server each day ?

Is it possible to add an external button to change the time zone (e.g. + 3600sec) Without it, you have to correct the code every six months.

welon

pls someone help me with the code to change time from 24 to 12 hours

can I use NodeMCU in place of ESP32 ? What changes are required with code ?

Cool project but why do the minutes up date at 59 seconds and not at 00

small tip:
P.setIntensity (0); for the brightness (insert in line 92)

Работи. Само трябва да се внимава да се запишат правилно, wi-fi адреса и паролата. На мен един интервал между буквите ми създаде много главоболия. И chatGPT неможа да ми помогне. :)
