Hello everyone! I hope you all will be absolutely fine and having fun. Today, we will have a look at the DHT11 Arduino Interfacing. DHT11 is an embedded sensor, used to measure both temperature and humidity of the surroundings. It is made up of two different parts i.e. capacitive humidity sensor and a thermistor. DHT11 is a slow sensor but is quite efficient for the applications where we need to do some basic analog data exchange. There is a small chip inside this sensor which performs the function of analog to digital to analog conversion and gives the results for temperature as well as for humidity in digital form. This digital signal can be read easily through any micro-controller.
LM335 is another temperature sensor and to understand today's p ...
Hi Friends! Happy to see you here. Thank you for viewing this read. Hope you’re well today. In this post, I’m going to discuss the Analog Flex Sensor Library for Proteus. You should also have a look at Digital Flex Sensor Library for Proteus.
I’ve been adding them over the last few days intending to design and share brand new libraries that are not a part of the proteus library database already. I’m adding both simple simulation and simulation with the Arduino board to help you better understand these libraries with microcontrollers and Arduino devices.
Before I go further and walk you through on how to download and simulate Analog Flex Sensor Library for Proteus, let’s get to know what’s Flex sensor first.
Simply put, a flex sensor is used to ...
Hi Guys! Hope you’re well today. Thank you for clicking this read. In this post today, I’ll walk you through the Introduction to B772.
B772 is a medium power bipolar junction transistor mainly used for switching and amplification purpose and belongs to the PNP transistor family. It comes in the TO-126 package and carries a collector current of 3A which means it can support load under 3A. The 60V is the collector-base voltage and 30V is the collector-emitter voltage while 5V is the emitter-base voltage which means it requires 5V to bias the transistor and start transistor action.
In this post, I’ll be discussing pinout, datasheet, working principle, power ratings, physical dimensions, and applications of B772.
Let’s get started.

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 ...
Hi Friends! Hope you are doing well. In this post, I'll uncover the details on How to use pinMode Arduino Command. The pinMode defines the Arduino Pins, if they are used as an input or output. The INPUT_PULLUP is another option achieved by pinMode, that is mainly used to place a virtual pull-up resistor to the input pins.
We have started Arduino Tutorials for Beginners quite a while now for the newbies, who are really interested to get a hands-on experience with Arduino. Generally, Arduino is known as a Microcontroller, but it is a step ahead of it. The PIC microcontrollers require some basic circuit to start with but Arduino brings revolution in the automation industry by removing the need of developing any basic circuit. Although Atmega328 is th ...
Hey Guys! Hope you are doing well. I am back to feed you with valuable information relating to engineering and technology. Today, I'll uncover the details on the Introduction to ATmega128. It is an AVR, 8-bit low power microcontroller, that comes with a 64-pin interface and is based on RISC architecture. Availability of 133 Powerful Instructions with single clock cycle and 32 x 8 General Purpose Working Registers make this device an ideal choice for many applications where decent code execution is required.
The memory space incorporates on this module is more than normal AVR controllers including Program memory around 128K, enough to store the number of instructions on a single chip.
In this post, I'll try to cover each and everything related t ...
Hello Everyone! Happy to see you here. I welcome you on board. In this post today, I’ll be discussing the Introduction to BC558.
BC558 is a bipolar junction transistor used for amplification and switching purposes. It belongs to the PNP transistor family and is available in a TO-92 package. It contains collector current 100mA, indicating it can drive load under 100mA.
I've previously detailed the Introduction to BC640 & BC327.
I suggest you read this entire post as I will cover a complete introduction to BC558 explaining pinout, working, power ratings, physical dimensions, datasheet, and applications of BC558.
Let’s jump right in. Continue reading.

Hello friends! I hope you all will be absolutely fine and having fun. Today, I am going to give you an elaboration on Introduction to 2N3772. I have already shared basic knowledge about different IC's and transistors in my previous tutorials e.g. Introduction to IRF540, BC547, MMBD914, LM339, LM224 and LM386. You must have alook at these tutorials before going into the details of this tutorials. It will be quite helpful in the better understanding of this article. 2N-3772 is basically a type of central semiconductor. It is basically a Negative Positive Negative (NPN) semiconductor. This semiconductor is designed by the process named as epitiaxial process. The main purpose behind its designing is to provide the high power based amplification proce ...
Hi Guys! Hope you’re well today. I welcome you on board. Thank you for clicking this read. In this post today, I’ll detail the Introduction to UF5408.
The UF5408 is an ultra-fast recovery diode that comes with quick recovery time. It is mainly used to rectify the sine waves. Upon rectifying the signal it converts the AC signal into a DC signal. This diode provides the DC signal to the electronic device since most of the electronic devices operate on the DC signal.
Just stay with me for a little while as I’ll discuss the complete Introduction to UF5408 covering datasheet, pinout, features, and applications of this component UF5408.

Hello readers, hope you all are doing great. In this tutorial, we are going to discuss a mechanism that allows users to update the ESP32 with a new program wirelessly or over the air (without using a USB cable to upload a new program).
Over-The-Air (OTA) programming
Fig. 1 ESP32 OTA
OTA programming is the mean by which a product manufacturer or product service provider can update the features or functionality of the device wirelessly or over the air, after the device has been deployed in the field where connecting a cable or uploading the code serially is difficult.
One key advantage of OTA is that a single central node can send an update to multiple ESPs on the same network.
The device must have a provisioning client capable of receivin ...
