wow, thanks for this cool explanation.. I curious with the mechanical of motor,,I believe it has 3 pins, and also has limit switch to detect the rotation and became sensor to stopping the motor, right? can you give me logic for microcontroller to make it stops? I used arduino mega,,I've try to use general limit switch + arduino program for the logic to stopping the motor, but I've failed to make it stop,, I believe you can help me for this,,thanks before for the advance
Its just a limit switch, so just read as an interrupt. The challenge is it will fire or miss the trigger, the way these motors is designed. the cut will trigger an early interrupt and sometimes you will miss a trigger because its not perfectly circle its oval. So you have to rely on some clever logic that takes both the time and interrupt into consideration, and if its too early ignore the int, if there is no int for long, stop it anyway.
@@HacktronicsIndia oh ok, got it,,so I need to combine with time delay too, right? I'll try it, but I believe that the stability of voltage will become factor of consistency of motor rotation, I mean the precision of stopping point. This will also affect how much delay I need to set. Thanks for advance, really appreciate it
@@mamenit6121 Yes you need a stable voltage supply, that's why we have used a 3A module in the project. So basically its a combination of lots of things
We have our servers on AWS, that's why the device is agnostics of the payment gateways, also difficult to do so much computation on ESP32. So our own API, talks to the bank API on AWS, the node device responsibility is just to operate the motors, and thus it makes them more secure. Also if one payment gateway is down, we can switch to another one, without affecting any functionality, and as we run on AWS lambda, the downtime of our API is almost rare.
We are working on a new simpler board with just UPI, if you want to purchase, please contact support@hacktronics.co.in. Code & Schematics not included, we will configure it with RazorPay.
I am building a system that uses RFID to make payments and am facing a lot of issues with the same. If you can guide me then it would be great. Hoping for a positive response from your end.
I am not validating, payment gateway is validating. We are interacting with various banks and payment gateways using their API for the same. Earlier if you see, we have a video where we just rely on SMS without any gateway, but that is school project, this is industrial once, and hence can't rely on SMS, need proper authentication and validation, that's where the intermediaries (Banks & Payment Gateways) comes into picture.
@@HacktronicsIndia hi thanks for the Info, if you want to get a payment notification on your device your device should get connected to internet or else you should have iot sim how Paytm sound box works
@@abhishekcgowda9773 It needs wifi, you can use a single Jio dongle to connect multiple vending machines, there is no eSIM concept here. The vending machine controller needs to be connected to internet. Also everything is automatic, so Paytm sound box like thing is useless, because no one would be there to monitor the vending machine.
This is not a consumer product, hence not for sale. This is just to show Hacktronics R&D capabilities. The board is programmed with our payment gateway account. This will be used by some manufacturers who incorporate our technology to create B2C products, and we will charge some percentage say 5%, based on sales to cover the payment gateway charges, accounting charges (for payment calculation and transfer), server charges, admin dashboard, software and support for customer like in case of failed payments, etc. The blank PCB we will offer later for projects like Mobile Phone controlled robotics car, or RFID based home lock, etc, as it has RFID, motor drivers, LED, buttons, I2C, WiFi & Bluetooth.
Contact support@hacktronics.co.in, however this is currently not for sale. Currently we are working on Admin dashboard, QA, business and legal aspects, as special licenses are needed to act as payment aggregator for end users.

Which controller you have used? Can you please post buy link for motor?

When payment is successful which online server will check it payment is successful or failed

How do payment successfull the information say to machine sms via which software will be used pls helps to my MSD projects.

you wont hear from him, if you call him the only thing he says " this is not a commercial project " and hung up

Hi
We are developed food vending machine,

Doubt is how you validateing UIP payments
