Greetings, and welcome to another tutorial in our series on the raspberry pi 4 Python programming. The previous guide covered the basics of transmitting data over the radio using the nrf24l01 chip in Pi 4. We also learned about interfacing Arduino and raspberry pi 4 and sending radio signals between the two devices. However, this tutorial will walk you through building a Raspberry Pi-based mobile phone with a microphone and speaker for making and receiving calls and reading text messages (SMS). This Project also serves as a proper GSM Module for the Raspberry Pi interface, with all the necessa ...

We're glad you could join us for another lesson in our series on programming for the Raspberry Pi 4. The previous chapter covered how to interface the USB barcode scanner with raspberry pi 4. We looked at different types of barcodes and what each stripe represents as well as the different types of barcode scanners available today. We also built a python program for the intelligent shopping cart and now our familiarity with barcodes and scanners and how they function has significantly increased. The benefits and drawbacks of its use were also discussed, but what we're interested i ...
Hello friends, I hope you all are doing great. Today, we are going to start a new section in our Raspberry Pi Programming Course. In this section-VIII, we will implement advance protocols in the RPi4 board. Today's our first lecture in this section and we are going to interface a USB Bar Code Scanner with Raspberry Pi 4.If you have visited any big grocery store, you must have seen, it's
quite important as well as difficult to maintain the products in stock
at all times. To ease the job, barcode technology is used because it can
easily maintain an organized database of your items, costs, ...
A low-literate audience can nevertheless have their voices heard and their questions answered by using an IVR system, as has been proven time and time again. However, achieving such aims in a development setting calls for a cheap system that welcomes input from various parties. RASP-IVR is an inexpensive IVR system that operates on a PI 4 and a local Global System for Mobile Communications modem. RASP-IVR was designed as an open-source, community-driven solution. It's unusual to find a customer-focused company that still uses human operators rather than an interactive voice response system. Cr ...

Welcome to the following tutorial in our raspberry pi four programming tutorial. In the previous tutorial, we learned how to build a raspberry pi four website monitoring tool. We say how beautiful soap is applied in browser automation tasks such as tracking website activities. But in this guide will discover how to utilize our Raspberry Pi 4 as a wifi repeater. If you want a lag-free wireless network, a wifi Wireless Adapter is exactly what you need. You may want to set up a wifi repeater if your signal is weak in certain rooms of your home or if you have entirely lost service in ...
Introduction
Welcome to the next tutorial in our raspberry pi programming. In the previous tutorial, we learned how we could run Xbox cloud on our pi 4. We found that we can run any game easily without lag or having raspberry pi shut down, proving that pi 4 is quite a powerful minicomputer. However, this tutorial will demonstrate how to use Python on raspberry to monitor websites. This Python program will execute on Pi 4 and watch over a website, alerting you whenever it changes or goes down. This is accomplished by keeping a straightforward webpage duplicate locally and monitoring for update ...
