The project is for study purposes. The objective is to demonstrate the sales automation process using Bitcoin and the Lightning Network.

Hardware:

Raspberry Pi 3 Model B;

Display 7" Official Touch Screen Para Raspberry Pi;

Water pump RS 385;

Bridge H L298N;

Software and Web Solutions:

Linux Raspbian in Raspberry Pi;

Apache Server + PHP in Raspberry Pi;

Html, Php, Javascript e jQuery .

In Raspberry Pi, I created a local web server (localhost) and in the root I put the files:

index.html

qr.png

payment_received.html

start_pump.php

stop_pump.php

coke.mp4

QR code from BTCPAY

BTCPAY Dashboard

In BTCPAY I create the invoice (payment button), so it generates a Lightning Network qr code for payment. I also set up a return url (notification.php), which is the destination BTCPAY will inform when a purchase order has any changes, such as payment receipt.

In the notification.php file is just the PUSHER code. It is the PUSHER that warns Raspberry that BTCPAY has received a payment.
