GOOD JOB

I wanted to make your clock, but your code has an error when compiling.'class TM1637Display' has no member named 'setColon' any help please Bob in the UK

this is a great tutorial for beginners

Excelent,Gracias ,,

Can i use 4x18650 batteries to power the stepper motor driver board?

Thank you for making this video

My rated current is 1.4 Amp. Do I still need to reduce it by 10%?

Ho

vey nice animation

Project ke Report h kya

Hi friends Thank to this channel I have tested the project and it realy works

how to download the code for this project

Brother, it's so amazing how u created a custom library . U need to take a look at the embedded systems field

Gold tutorial. I was having so much trouble understating how to use these and you made it simple and it worked for my project! Thank you for the time you put into this!

$api_key_value = "tPmAT5Ab3j7F9"; where to get this? thanks

Bro please can I get ur Whatsapp number please i have some projects at hand that i need some guardian from you is about this color sensor

why do i hear clicking sound? no audio output from sd card

Love this video! Which stepper motor did you use?

Sir if we have to add Lcd 16x2 I2c module then what will have to change in code and connection for circuit please reply sir

hi Tectutor. Working ds3231-rtc-with-arduino-including-digital-clock-using-LCD displayI got your code which calls for ds3231.h and IDE errs : cant find . I fetched this ds3231.h file and got in my disk. How I must tell IDE to consider this file that resides in my computer?. HOW Thanks Dr J

How about a gate?

Hi brother, im currently working with stepper motors, im unig arduino sheildv4 with arduino nano. and IM unable to control the motors. the motor is is making little sound. when i try to change the wire (figuring out two coils) it vibrates the motor a lot. not sure where the issue is. can you help me in providing some code to get started with that board? Im surprised why there is not evena single comment yet. Keep going buddy. i wish to see you grow

My project is working but if we press switch button they automatically close the alam window in 1s.

thanks a lot.... I made this for my sem project💝

Great

I have been looking for a thoroughly explained tutorial on the working of TTP223 Touch sensor and I have to say this is one of the best.

Cool project! A couple questions that I hope won't take too long to answer. 1) Are the buttons momentary contact or latching? How would I go about turning this into a sunrise alarm clock--can I just hook an LED cluster to another output pin and start ramping up its rightness a few minutes before the alarm goes off?

Before you post it why don't you learn how to speak English

It work for 1 kilo meter if you have a transmitter with antenna

Give the circuit diagram

I’m new to this , what is the program you use to put your code on ? 4:57 , like in where I should create the code , does it work if I use any IDE or is an specific one ???

can i use 1,8 inch screen instead of 1.44 inch???

can i use 1,8 inch screen instead of 1,44 ?

Very good video. 👌

Extremely helpful video! Thanks!

How can I control servo with this using Bluetooth?

The arduino code give me Error code -1. Can you help me please?

Thank you for the great class teacher! Worked perfectly. Big hug.

Very good work, sir ! Is it possible to change the lux value of BH1750 sensor in W/m2 ? Thank you

Great to see you making videos again.

Perfect, great description.

I tried to do the same wiring and setting according to the video, but why the PWR/Alarm keep blinking and the the motor doesn't rotate🤧?

i luv u it was super helpful

Thank you so much for this wonderful and clear tutorial! You are an EXCELLENT instructor. I have many years of electronics experience (mostly vacuum tube stuff) but little automation or Arduino experience. However, thanks to your tutorial, everything made perfect sense. In particular, I want to commend your clear and plain identification of the details. Things like exact driver module model and wiring pin outs, schematics and so forth. This kind of info can take a lot of time to root out, and the manufacturers seem oblivious to the need to post it. Your pacing was just right - not too slow, not too fast - and you DID NOT ASSUME that "people already know that". Many do, some don't. Also, the Arduino code was extremely helpful, plus your handy tip on discovering motor winding orientation is worth the price of admission! Well done and thank you. Great job!

Please send components list

Thanks for sharing this information. Very helpful. And you are a great teacher.

Please upload next video on making a project on how to convert RFID signal into audio when RFID tag is detected using Arduino atmega ,df player mini and RFID sensor + tag if you don't this I will add 5 subscribers to your channel please please 🥺 I have tried it so many times but I failed😢

http request post is not shown in your video

I am not sure how changing the names in the files actually customises it. I followed all the instructions, loaded the code and it wouldn't compile.... a total waste of time! Plus looking below, other people have had problems, but you do not respond???
