Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to how to tweet from Raspberry pi. We also discussed some methods used by the tweepy library to perform some API calls in our project. We will learn how to print from a Raspberry pi in this lesson. Let us get started There are several benefits of having a print server. Print servers may link numerous computers to one or multiple printers, either physically or wirelessly, allowing you to access the printer with various devices and send print instructions from all the other connected computers. It is not easy to print from an Android smartphone to a cabled printer; however, a printer server makes it simple. A print server is useful in small workplaces where employees may print from any busine ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to configure our raspberry pi for voice control. We also discussed some methods of reducing vexing noises so that the voice command program understands you. However, in this lesson, we will learn how to tweet from Raspberry pi. What will we learn? Assume you wish to add tweeting into a Raspberry Pi software you're developing. This article will show you how to build a Twitter app, get access privilege tokens, and post a tweet. On our Raspberry Pi, we'll make a simple program that tweets the result of the uptime command. This is a made-up example, but it demonstrates what is needed to tweet from a raspberry pi. For this session, a repo has been set up. Because we'll be referring to code withi ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to make a button-controlled "music box" that plays different sounds depending on which buttons are pressed. In this lesson, we will configure our raspberry pi for voice control. What will you learn? Like the Amazon Echo, voice-activated gadgets are becoming increasingly popular, but you can also construct your own with a Raspberry, a cheap USB mic, and some appropriate software. Simply speaking to your Raspberry Pi will allow you to search YouTube, view websites, activate applications, and even answer inquiries. What will you need? Because the Raspberry Pi lacks a soundcard or audio port, this project requires a USB microphone or a camera with a built-in microphone. If your mic only has an ...
Hello readers, I hope you all are doing great. In our previous tutorial, we discussed the implementation of LED interfacing and blinking program with Raspberry Pi Pico using MicroPython programming language. So continuing with our previous tutorial, in this tutorial we will learn how to control the LED brightness using PWM (pulse width modulation technique). As we mentioned above, in our previous tutorial we implemented the LED blinking program with a Raspberry Pi Pico board. Blinking an LED means turning ON and OFF and thus the process involves only two states that are ‘1’ (HIGH) and ‘0’ (LOW). But, sometimes it is required to change the digital output between these two (ON and OFF states) for example changing the LED brightness. PWM or Pulse Width Modulation technique is used to change t ...
Welcome to the next tutorial of our Raspberry Pi programming course. In our previous tutorial, we learned how to create a timelapse video with still images and understand how phototimer and FFmpeg work. In this lesson, you'll make a button-controlled "music box" that plays different sounds depending on which buttons are pressed. What you will learn Connect button pushes to function calls using the Python gpiozero package and uses the Python dictionary data structure Components Raspberry Pi Breadboard Buttons Jumper wires Speaker Set up your project For this project, you'll need some audio samples. On Raspbian, there are many audio files; however, playing them with Python can be challenging. You can, however, transform the audio files to a more simply used format for Python. Please make a n ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial looked at how to Interface DS18B20 with Raspberry Pi 4 . This tutorial will teach us how to create a time-lapse video with still images and understand how phototimer and FFmpeg work. What is time-lapse? When photographing something over a lengthy period, "time-lapse" comes to mind. A video can be created by mixing the still photos. Plant development may be tracked with time-lapse movies, as can the changing of the seasons. They can also be utilized as low-resolution security cameras. Components Raspberry pi 4B Pi camera Connect to the Raspberry Pi Cameras that can be used with the Raspberry Pi are a bit limited. A powered USB hub is required for most webcams that are compatible. For this post, we’ll ...
Hello readers, I hope you all are doing great. In our previous tutorials on raspberry pi Pico, we discussed the basic features, architecture, download and installation of development environments for raspberry Pi Pico programming. In this tutorial, we will learn how to access and control Raspberry Pi Pico and its GPIO pins to implement LED blinking using MicroPython. Introduction Raspberry Pi development boards are quite popular and frequently used among students and hobbyists. But the drawback of Raspberry Pi is their cost i.e., around $35-$45. So when cost of the development board is of prime importance the users prefer to use ESP8266, ESP32, Arduino, PIC etc. over Raspberry Pi. To overcome this drawback, Raspberry Pi foundations designed a new board i.e., Raspberry Pi Pico which is a co ...
Abstract: This paper is written to represent a web-server based real-time weather monitoring system implemented using the ESP32 module. The system is designed to measure the weather conditions like temperature, pressure, humidity etc, in its vicinity. This system continuously provides real-time data (weather conditions) over limited or controlled areas, for example, agriculture fields, homes or a particular room, industries etc. Although we have satellites for weather monitoring but to perform research over a particular area, the data observed should be highly accurate which is not possible with satellites. To implement an IoT network we need to use a webserver to continuously store and display the real-time data which can be accessed globally. ’ThingSpeak’ is a web service where one can u ...
Hello friends, I hope you all are having fun. Today, we are going to share the 7th tutorial of Section-III in our Raspberry Pi Programming Course. In the last tutorial, we interfaced a DHT11 sensor with Raspberry Pi 4 . Today, we are going to interface another temperature sensor i.e. DS18B20 with Raspberry Pi 4. DS18B20 is a popular temperature sensor especially in severe/critical environments i.e. chemical plants, mines, industrial sites etc. because of its 1-wire operational technique and accurate readings up to 4 decimal digits. Project Description Today, we will interface a DS18B20 temperature sensor with Raspberry Pi 4 and will display the values on a 16x2 LCD. Let's have a look at the components required for this project: Components Required Here's the list of components: DS18B20. Ra ...
Hello friends, I hope you all are doing great. Today, I am going to share the 6th tutorial of Section-III in the Raspberry Pi Programming Course. In our previous tutorial, we have seen how to interface an Ultrasonic Sensor with Raspberry Pi 4 and used Python to perform its calculations. In today's tutorial, we'll discuss how to interface a DHT11 temperature and humidity sensor to a Raspberry Pi. So, let's get started: Components Here's the list of components, we are going to use in today's circuit: LCD display DHT11 sensor Raspberry pi Breadboard Male-to-female jumper wires What is a DHT11 sensor? DHT11 is a low-cost digital sensor, used to measure temperature and humidity in the surroundings. DHT sensor has three main components i.e. A resistive-type sensor(used to measure humidity) NTC T ...
