[@vankavinaykumar]

Can you create a video on how to make a vending machine, like generate a QR code which accept payment of certain amount and once that payment received ee can turn on something may be led or something for certain duration

[@drelectronics13]

Definitely it's the best tutorial so far , I hope you ll make a small series on this to implement on other things instead of just using it as payment box❤

[@techiesms]

Thanks. And what kind of small things are you thinking to make with this?

[@puneethku2241]

Hi bro i have seen your video quite straight forward. Although am an embedded engineer am impressed my suggestion is that better you start tutorial stuff where i will be your first student.

[@avinashgahlowt4665]

Do you call any get api of UPI to know that his much payment has been made or the payment is successful,in short how does the box knows that payment has been made, cz qr has the static info so then how the data reached to box regarding the payment

[@dharmikbhavani7272]

Don't you think a stencil for this is little overkill for such simple soldering job. Also not all heating devices are oven its name is reflow.

[@roboticskanti]

Hmm very interesting project 👍 keep going….

[@techiesms]

Thank you 😇

[@sandeshmadnur2353]

i love your videos sir ♥♥ keep growing

Thanks a ton

[@Stalwart-e6s]

Bhaiya , do you run online course? if not, we would certainly want so that school kids can also learn these things.

[@Venudgowda]

Sir, why you are choosen MQTT protocol, we do with simple SMS. Right.

[@ammaramjawala5484]

Would it be easier with s3box? Also once can generate dynamic QR (fixed amount)

[@sabarib6932]

Sir what is the main reason we are using MQTT server We can use HTTPCLIENT also whats the difference

[@hackerbot9123]

Wonderful project 🔥

[@techiesms]

Glad you like it!

[@nemesis851_]

5 months ago you mentioned you would figure out how to get Squareline Studio working with GigaShield Display

[@techiesms]

yes, I remember but a lot of projects are going on in parallel so didn't get time to learn that x

[@eShrut]

Whats the role of mqtt here, who is sending payload to mqtt topic? PayTM? or you have a app for it? why esp32 is used if simcom board is there.?

[@lalmohanpadhy4380]

Is it possible to make without sim

[@techiesms]

You can make with WiFi as well

[@ShivRajNetwork]

[@adityanathpandey4060]

If wifi is not used then atmega 328 p smd version could be a cheaper option?

Upi printing video you have used Rx Tx pin in connection to connect printer. But this video sound box you connect rx tx pin to sim module. So can I used Bluetooth to connect any thermal printer which is available in Amazon?

[@techiesms]

Well not exactly sure about that So can’t say anything

[@basicelectronics6324]

Awesome 😍😍

[@techiesms]

Thanks 🤗

[@anithasshenoy6662]

Project is very nice. Worth the effort and money. But how do you get information from the bank that payment has been made / or what is source of such info ?

[@techiesms]

I didn’t get your question Can you please elaborate

[@anithasshenoy6662]

@@techiesms thk fro responding. When some one makes payment , by scanning or by phone number, how do you get that information ? is it by actually connecting the bank account of the dealer ?

[@techiesms]

@anithasshenoy6662 in UPI along with the payment, there are a lot of information shared about that payment to the payment gateways via web hooks and that how we can know everything No need to connect any bank account for that

[@anithasshenoy6662]

[@SaddamHusain-ih3sf]

Great project sir

[@sisotechh]

Good One! And what if multiple people were trying to pay from it. It would say only of 1 person right, who paid first?

[@techiesms]

We tested this and found that it plays all the amount received one by one

[@proudtobeindian9778]

[@gauravdashora5757]

Can we connect Bluetooth Printer to print payment received ?

[@techiesms]

I made a separate video about printing payment slip Check that out

[@gauravdashora5757]

That video you have used Rx Tx pin in connection to connect printer. But this last video sound box you connect rx tx pin to sim module. So can I used Bluetooth to connect any thermal printer which is available in Amazon?

[@nagarava]

I want to use wifi without using a sim800, please modify code

[@techiesms]

Watch out the episode 2 of webhooks series and in that I have used WiFi only.

Hi. You are an expert in radio-electronic equipment. I need to make a device, myself!!!, to measure microwave radiation anywhere from 1 GHz and preferably up to 40 GHz. Not an instrument! It's a probe!!! An instrument is complicated. A probe is about understanding what it would be.
