Welcome to the next tutorial of our raspberry pi programming tutorial. The previous tutorial showed us how to set up a weather station using the Internet of Things (IoT) on a Raspberry Pi 4. First, we studied how a weather station works on a fundamental level. Then we developed a Python script to collect data from the station. In contrast, we'll construct an automatic gate using a Raspberry Pi, a load cell, and an HX711 weight sensor.
These pressure-sensitive gates are common in shopping centers and showrooms; they open when someone is in the immediate vicinity and close again when the person is out of sight. Like the Automatic Gate, we just made, this one will open in response to weight or pressure and stay that way until the force is removed. If ...

What are Flip Flops?
What are JK Flip Flops?
How can we record the Truth Table of JK Flip Flops?
What is the Procedure to Construct the circuit of JK Flip Flop through Logic Gates and IC circuit?
Moreover, we'll also have some useful bits of Information in Did you know Sections. Let' see the explanation of the concepts given above.
Flip Flops
The Flip Flops are the building blocks of many of the Electronic Circuits. ...
Hey Friends! Hope you are doing well. This is a platform where we keep you updated with a major development in engineering and technology. Today, I'll uncover the details on How to Organize and Manage Final Year Project?
You get rolled in the first semester of engineering, and within no time, you will be attending your final semester. Each semester helps you make a better version of yourself and allows you to convert your knowledge and expertise into reality.
When you reach the final year, you need to develop a final year project. This word looks quite intimidating for some students and they feel quite overwhelmed before planning and managing their project. However, if you have a proper plan in place and work with consistency, there is no need t ...
Choosing a prototyping firm to manufacture your things is a crucial decision. Identifying the right match is a difficult task for any firm. Cost, effectiveness, dependability, and operational processes must all be considered before assigning any production assets.
Dealing with a prototyping firm should be straightforward once you learn what to look for. The following are important considerations to consider while looking for a producer to help you bring your prototype idea to life.
Familiarity with the Business
You can look through the portfolios of the best prototyping businesses to see their previous work. This data is crucial in determining whether they have experience with similar initiatives and specialize in your required prototypes.
You'l ...
Hello everyone! I hope you all will be absolutely fie and having fun. Today, I will elaborate you about Introductio to NE556 timer IC. NE-556 is a lot stable monolithic device. We can use precise delays and oscillation by using this device. NE 556 is bsically an dual version of NE 555 timer IC. Timing is provided for each function using an external capacitor and resistor. There are two internal timers which operates independently. They just share common power supply and ground. For the falling or rising wave forms we can trigger or reset the entire circuit.
The trigger level and the threshold levels are usually one third and two third respectively. We can alter both of these level by using control pin of NE-556. If the input at trigger falls bel ...
Hey Guys! Hope you are doing great. Today, I am going to discuss the details on the Introduction to BJT (Bipolar Junction Transistor). It is an electronic component mainly used for amplification and switching purpose. As the name suggests, it is composed of two junctions called emitter-base junction and collector-base junction.
Don't confuse BJT with regular transistors. A transistor is a semiconductor device, comes with three terminals that are used for external connection with electronic circuits. A transistor is termed as a trans resistor which is used as switch or gate for electronic signals. Small signals applied between one pair of its terminals are used to control much larger signals at the other pair of terminals.
Actually, transistors are divided into two categories called u ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How Reliable Is Opera's Built-In Free VPN. Opera’s built-in free VPN is one of the most exciting and innovative features on any web browser. They are the first company to recognize just how important VPNs are to our security and privacy. Using it is as simple as clicking one button. However, the old cliché is true that there’s no such thing as a free lunch. We’ll look at some of the pros & cons of Opera’s service along with the other mobile VPN choices you might have.
Why Should You Use Opera’s VPN?
It’s built-in to the browser. This means you just need to download Opera, enable the VPN, and you’re good to go. Better than this, it’s free, but still provid ...
Hey pals! I wish you are doing great. Welcome to a new lesson about the Digital Logic Circuits in The Engineering Projects. In the past tutorials, we Designed the Basic JK Flip Flop. Today, we'll talk about the following Points:
What are JK Flip Flops?
What are the Master Slave Flip Flops?
How does the Circuit of Master Slave Flip Flop looks?
How types of JK Flip Flop different from each other?
How does the simulation of Master JK Flip Flip take place in Proteus ISIS?
Moreover, we'll also learn some key concepts in DID YOU KNOW portions. Yet Let's recall some points about the topic. Flip Flops are the building block of a huge number of electronic systems and devices. A Flip Flop is a Digital circuit that can take the bits as input, wor ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a new project which is Password Protection using PIC Microcontroller. In this project I am going to use keypad and LCD and will be designing a system in which I am gonna drive a motor if the correct password is supplied. If you entered the wrong password then the motor will not move and you will get another chance to enter the correct password. I hope you guys are gonna enjoy this one.
I have used Keypad, LCD and PIC Microcontroller in order to design the simulation in Proteus ISIS software. You should also have a look at Electronic Door Lock using PIC Microcontroller, which is quite similar with the only difference of keypad. In that previous project, ...
Hello everyone, I hope you all are doing well. In today’s tutorial, we are going to discuss the PCB Etching process, a fundamental step in PCB manufacturing. The PCB Etching process is used to remove the unwanted copper from the PCB surface to reveal the desired circuit pattern.
As we know, a PCB board has a complete copper layer in its raw form. We design our circuit in the software(i.e. Eagle, Altium, Proteus etc.) and place the pattern on the PCB board. This circuit pattern is normally protected by the tin plating, as shown in the below figure:
Now, there’s a need to remove the extra/unwanted copper layer from the PCB board and this process is called the PCB Etching Process. PCB Etching is carried out in various ways and the most commonly used i ...
