Update: I have updated the code and removed the bug. Thanks for informing. Now this code will work perfectly.

Hello friends, hope you all are fine and having good health. Today, as the name suggests, I am gonna post on how to Receive SMS with AT Commands using Sim900 and Arduino. I have already posted a tutorial on How to Send SMS with Arduino UNO and Sim900, so now we are gonna check the opposite. Sending SMS is quite easy, you just need to write some AT commands and write the message you wanna send and hit the Cntrl + Z and it will be sent. But receiving a text message on your SIM900 shield is a bit difficult because now you need to place a check when user will send a message. So, ideally whenever anyone send a message to yo ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at Datatype Conversions in C#. We have discussed C# Data Types in our 3rd tutorial and today we will discuss How to convert one datatype into another.
If you are working on some complex project, then you have to convert one form of data into another i.e. let's say you are getting bill value from barcode reader, this value must be a string and if you want to apply any arithmetic operation on it then you need to convert that string into integer or float. So, let's get started with Datatype Conversions in C#:
Datatype Conversions in C#
If you are working on some data driven application, then there's always a need to convert one form of data into another an ...
Hello friends, I hope you guys are doing great. In today's tutorial, we will have a look at How to Install Solar Panels While living in Dorm. As global warming continues unchecked, the masses are becoming aware of the need for eco-friendly solutions. With numerous innovations at hand, it only takes a little effort to reduce our carbon footprint. The younger generations are much more aware of the impact of global warming and the need to become more environmentally friendly.
One way to effectively conserve energy is by using a clean, renewable source of energy, such as solar energy. Solar energy is an excellent way to reduce one’s carbon footprint, and numerous students are now turning to it to power their dorms.

Hello friends, I hope you all are doing great. In today's tutorial, I am going to explain How to Create PWM in Raspberry Pi 3. In our previous tutorial, we have seen How to Create GUI in Raspberry Pi 3, & we have also controlled an LED from the GUI Buttons. So, I am gonna take that project and will add PWM code in it.
So, I would recommend you to first have a look at LED Blinking with Raspberry Pi 3 in which we have designed this simple project and then check How to Create GUI in Raspberry Pi 3, where we have controlled that LED digitally with GUI. But today, we are gonna control the intensity of this LED by creating a PWM Pulse in Raspberry Pi 3. Along with that, we are also gonna have a look at How to use Scale in Raspberry Pi 3. I will add ...
Hi Guys! Hope you’re well today. In today's tutorial, we will have a look at the 2SC1345 NPN Transistor. We will also discuss 2SC1345 Datasheet, Pinout, Power Ratings, Equivalents & Applications. As this is an NPN transistor, the conductivity is mainly carried out by electrons as the major charge carriers. 2SC1345 is mainly used for switching and amplification purposes.Let's first recall NPN transistors: NPN transistor comes with 3 terminals, named:
Emitter
Collector
Base
If the voltage at the base terminal is above 0.7V, the NPN transistor gets forward biased & starts conducting i.e. current will flow from the Collector to Emitter terminal. If the Base voltage is less than 0.7V, it remains reverse-biased.So now let’s get started with the 2SC1345 NPN Transistor.
2SC134 ...

Hello friends, Hope you all are fine and having fun with your lives. In today's post, I am going to show How to display a Scrolling Text on LED Matrix 8x8 using Arduino in Proteus ISIS. We all know about LED Matrix but if you don't know then google it. :P LED Matrix is used to display long messages, the best thing about LED Matrix is you can combine then in serial way and can make it of any size you want. Like in this post I have combined 8 LED matrices and then displayed my message on them. I have given all the details here but as you can see we have done a great effort in designing this simulation so I haven't posted it free but have placed a very small amount of $20 on it and you can buy it quite easily from our shop by cl ...
Hello everyone, Welcome to our new project. Our new project plays a very important role in our daily life as it is directly connected to our lives. In this project, we are going to design an Accident Detection module. Accidents are the most common thing we hear about in the news, and in social media. Everyone here or there has seen accidents or has been with one. So when any such incidents happen, we inform respective stations or hospitals in that emergency situation. But what about the accidents that happen at night, or in places where there is very less crowd or you are alone. So, to address this issue and provide a potential solution for that, we are going to learn how to detect an accident automatically and inform nearby aid/help stations.

Hi readers! Welcome to another article where we are discussing the MQ family members. Today, our motto is to learn about the MQ-5 natural liquified petroleum gas (LPG) sensor. The gas sensing material used in this sensor is known as tin dioxide(SnO2). It detects the natural LPG in the surroundings as soon as the core material of this sensor comes in contact with the LPG. This will be explained in simple words in this article.
Today, we’ll start learning about the basic introduction of the MQ-5 natural LPG sensor. After that, we’ll move towards its datasheet element, where we are going to see the specifications and features of the sensor, along with the pinout configuration and internal structure. We’ll also see the working principle and applications of the MQ-5 natural LPG sensor, and a ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to MPR121. MPR121 is a touch sensor controller, its working is like the capacitor's working principle. This module has twelve electrodes points, it communicates via I2C protocol. When any objects come closer to an electrode point, we can observe the presence of an object by variation in capacitance of an electrode. It's working voltage should be between 2.5 to 3.6 VDC.
MPR121 is used in different industrial projects and electronic devices such as mobile phone and remote control systems. In today's post, we will have a look at its working, pinout, protocol, applications, etc. I will also share some links where I have interfaced it with other microcontrollers. If you have ...
