We discuss different properties of atoms ...
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 ...
This is the third tutorial in our Raspberry Pi programming course. In the previous chapter, we learned how to install Raspbian on our Raspberry Pi mini-computer. In this chapter, we'll learn how to use a VNC server to remotely control and see its desktop from our computer.
What is VNC?
Computing over a network is known as "virtual network computing," or "VNC." To remotely control another computer, you can use this screen-sharing technology, which works on all major operating systems. As a result, a remote user can interact with a computer's display (screen, keyboard, and mouse) as if they were sitting right in front of it.
VNC takes advantage of the client/server concept. Rather than installing a VNC s ...
Hi Friends! Hope you’re well today. I welcome you on board. In this post, I’ll walk you through How Workflow Automation Can Benefit Small Businesses?
Reduce the possibility of human error, save time and improve efficiency – The main goal of workflow automation. If your employees spend a lot of time on mundane and repetitive tasks, it’s a high time to invest in workflow automation. Especially if your business is small and you are in the early stages to leave a footprint in the competitive market. You can’t afford to hire scores of employees to do predictable tasks that you can automate with workflow automation. For instance, follow-up emails and sales calls, finance approval and invoice generation, and onboarding new employees, you can automate these tasks without having to worry about hir ...
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 ...
Hello readers, we hope you all are doing great. Welcome to the 1st lecture of Section 4 in the ESP32 Programming Series. In this section, we will interface the ESP32 module with common Embedded modules(i.e. LCD, Keypad, RTC etc.).
In today's tutorial, we will interface ESP32 with a 16x2 LCD and will display data using both Data Mode and I2C Mode. LCD is the most commonly used embedded module in IoT Projects. It is used to display different types of data i.e. sensor readings, warning messages, notifications etc.
Before going forward, let's first have a look at what is LCD and How it works:
16x2 LCD Module
LCD(Liquid Crystal Display) is a type of electronic display module that is used in a wide variety of applications and devices such as calculators, computers, mobile phones, ...
Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through Cloud Computing Services.
The requirement to process and store data varies from business to business. Some organizations can handle data in on-site data centers. They have a team of experts who handle IT infrastructure and install, maintain and upgrade hardware based on the availability of data. This approach is expensive, no doubt. Some companies, however, don’t accept this model. They prefer cloud computing which is the availability of on-demand IT infrastructure over the internet. This model sets them free from handling and managing on-site data centers, instead, everything is managed and controlled by the cloud service providers. End users only pay for the computing services they use. ...
Hello friends, I hope you all are doing great. Today, we are going to share the 2nd tutorial of Section-VIII in the Raspberry Pi Programming Course. In the previous tutorial, we interfaced a Barcode Scanner with Raspberry Pi 4. In today's tutorial, we will discuss how to set up a web server in raspberry pi. So, let's get started:
Components Required
We are going to use the following components, in today's project:
Ethernet cable
MicroSD card
Keyboard
Mouse
HDMI cable
Monitor
Expand FileSystem
When configuring a Raspberry Pi, select the expand FileSystem option to ensure that all of the Micro SD storage is allocated for the operating system and modify the default Pi passwords to protect your server from attacker ...
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. ’T ...
Hi Everyone! Glad to have you on board. Thank you for clicking this read. In this post today, I’ll cover Real Life Examples of Workflow Automation.
Workflow automation is a talk of mainstream conversation. Many employees use this process in their organizations but they are not aware of this term. Workflow automation is a process used to automate manual and repetitive time-consuming tasks. It requires a series of tasks that need to be completed in a sequential manner where the process goes from start to finish with a definite goal in mind. For instance, onboarding new clients and approving leave requests are susceptible to errors when done manually. However, with workflow automation software, these tasks are done automatically without human intervention, leaving no room for mistakes or fai ...
