Thank You, worked like a charm.

Bonjour j'ai un problème l'heure récupérer elle une différence d'une heure avec celle du mon pc

sir aap is not opening

doest this work for any programs or only for PIN 13

It looks like this app isn't available How can I solve this brother?

Special thanks for the tip about changing gps baud rate.

My lcd won't turn on

عمل رائع و ممتاز . أخ أحمد هل هناك طريقة لتحويل hex إلى code source .وشكرا مجددا

Bro i have installed all liquid crystal library but i get error like " no maching function for call to Liquid Crystal_I2C ::begin()

I am getting authentication failed for write:timeout in communication while uploading card details

Thank you so much ❤, Ahmed bhai apka ye method mere liye bohat hi helpful rha hy.

❤

i cant store data, anyone can help

Thank you for the video. Very helpful!

how long will it take to connect to satelite sir ???

Where can I develope circuits such as in your thumbnail?

Can any one say where we have to give phone number or no need to give the phone number in code please help me

how to solve this? [HTTPS] GET... code: 403

Hi, I'm planning to switch to an Arduino Mega 2650, but for some reason I'm not getting data from the tx pin. It's connected to D2, should I use the rx on the gps and connect it to pin 3?

Sir can I use 4g sim instead of 2g sim

hello sir can you teact me on how to use the lcd

perfectly working

Battery used?

Hi, I created your project but it doesn't work. There are defects in the connection diagram

nice video , please can you provide us an example of a real time monitoring system based on dht11 , co2 gaz sensor mq135 and mq2 and a flame detector please i need some aid for my project

Bro... Guide me about gsm sim 800L...its not working

non funziona e poi i pin dello schema non sono gli stessi del programma

Can it work with gsm too?

Sir How i can contact you?

Could you please say what did use battery to connect with gsm or gps module

Sir which sim we have to use 2g 3g 4g

Sir give code for esp8266

Dear Ahmad, Thanks for the very helpful video. I have a few sim800L GSM modules (3.3V and 5V) which I was trying to sort out for a wireless alarm notification. I did have a GSM wireless chinese alarm with a dodgy battery. It also stopped showing a GSM/wifi connection. I now think this is all due to a requirement for a battery due to the 2A burts. Despite what some videos show the 5V does not connect and reboots even if attached to a 5V USB power adapter attached to the arduino, or PC. I am now thinking that maybe the issue for all mobile phones, sat nav etc. needing a battery may be this 2A burst for the GSM modem. Do you think this correct? In relation to this, can any ordinary lithium 18650 battery be attached. I note that there is circuitry often attached to the lipo batteries. Can 18650 batteries be used without this circuitry to get phones etc to work of the mains usb adapter?

Hello, I'm using an ESP32 too but mine is 38 pins, which board should I choose in the Arduino IDE?

nice one

How you are powering the esp through vin pin or cable also how much power you are supplying then what is the source of power like laptop or lithium battery

Am doing rfid rc522 attendence system using arduino with data logger ....in this am getting the SD card initialization failure ....what was the problem in this ..could you please reply me ..whats the problem...am not getting the output

So clickbaity and fake title. There's no AI and there's no automation at all. In fact, it's embarrassing to put AI in the title.

Ahmad, Built the clock, loaded the sketch, but at the line "char *number[12]={"6","5","4","3","2","1","12","11","10","9","8","7"};." When I verify, I get the following error message "warning: ISO C++ forbids converting a string constant to 'char*' ". However, the program does compile and run. Should I be concerned about this message? It is way beyond my level of programming to really follow what it is doing. Thanks.

Great, guy! Thank you!

in my case, i have used step down buck convertor and i had set it to 4v, it still facing the power issues(7 times blink and reset), then i have the increased the voltage to 4.35v still i had faced the power issue. but totally, i removed the step convertor and connected directly to 5v by using this capacitor trick. finally it worked!!!

Enter Last Name, ending with # Authentication failed for Write: Timeout in communication. Authentication failed for Read: Timeout in communication. I get error like this,How to overcome this

THANKYOU SO MUCH

IS SIM800l SUPPORT 4G AIRTEL SIM

The problem is that I can't change the state of the relay. Theoretically, when I press on a switch on my phone, the relay should be open/closed. Instead, nothing happens. I've checked the pins connected to the relay; they are powering on/off, so I doubt that it is a coding issue. But nothing is there in coding part or connection. So how to resolve ta issue. Please help

Did you insert the 2g sim into gsm module

greate

My esp32 read file 29%after heng what is problem ???

Good Job Men, Thank You
