Thanks for sharing this. Please could you help with the link to the LiquidCrystal_I2C library that you used in this project ???

​@IoTLearner Sir I have not used the leds yet, when I tried to start the system, the lcd was not working (it was just lit up, no words were on it) is it because I didn't used the leds or my lcd display is not working?

hello sir, i dont have any idea i follow your instructions. idunno if my rfid reader is working but the LED light is ON when i upload the code to my nodemcu and rfid reader it doesn't read my rfid tags. can you help me about this..

Great work. Works well. Just a small issue being my esp8266's onboard blue led light is flashing non stop. Do you perhaps know how to stop it or disable it?

Can you tell some beginner projects to check interest in IOT?

which acc to you have better pay and future web dev or IOT ? As I have seen everyone doing web dev but no one talking about IOT

This was exactly what I needed, thank you so much!!!

I have knowlege of software development with MQTT if any one has hardware side knowlege we can connect and contribute

@IoTLearner bhaiya. i really need your help. I'm CSE 3rd year student. currently i found interest in IoT. i made many basic project on home automation. since i am a computer science student i have done C,C++,python, web development course but this didn't excite me.. i don't want to code only. i want to code for things which can result some movement, changes in position etc. bhaiya i am afraid that if i choose IoT then i have to start from scratch and also it has low income and my 3 year of hard work in coding will go waste..and if i choose web dev then perhaps i can't be able to enjoy it. 1. if i choose IoT then which field should i choose? embedded (hardware) or software part? 2. should I not change my domain from Web Development ?? plz, reply .eagrly waiting for your reply.

I’m getting an compilation error: Liquidcrystal_I2C.h : No such file or directory

Sir i am doing the project(rfid based smart attendence system using firebase and nodemcu) but i face one difficulty when i scan the rfid card for first time card is detected and all the values are stored in webpage but for second time when i scan the card again then in serial monitor i show an error is generated (path not exist) sir plese give me the solution to solve it.

Firebase.setInt(firebaseData, uidPath+"users/"+temp, 0) does not work. But when I input it as a whole string like "/users/temp" then it works. Anytime I use a variable and concatenate strings, it doesn't work. Why does this happen?

hello, im following your board, but my nodemcu cannot read the RFID, why is it? and it shows in the serial monitor "fi....⸮⸮" please help

Which language choose to start iot please tell me 🙏

if you don't know how you have written and taking data from others working sources then don't make video after spending time with your video not one thing you have not explain so all things are ruined .

Not able to understand how to write client id . You have written something else while showing something else. explain it in comment that are creating confusion and this thing also not working best on this issue

kindly let me you have taken data from real sensor or vertual sensor and vertual raspberry pi board . I have not any board write now can I do this for learning purposes this thing
