Hello friends, I hope you are doing very well. Today we are going to learn and practice the master control reset (MCR)! So what is that MCR? Well! This is a tool you might use to control a group of devices with one push button for performing fast emergency responses with one click for a group of devices in one zone. In another word, you divide the program into zones and put this zone between a master control to control their operation as one unit by one contact. This technique is useful for applying emergence stops and also protecting some equipment by applying a safety restriction to not operate when that condition is in effect.

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to LM335. LM 335 is basically an Integrated Circuit (IC) for precise temperature sensor. LM-335 operates on a current range 400uA-5mA having resistance less than 1 ohm. At 10mV/K, its absolute temperature becomes directly proportional to the breakdown voltage.
LM-335 operates as two terminal zener diode. At the temperature ranging from -40 degree Celsius to 100 degree Celsius, LM 335 can be used for each type of temperature sensing purposes. This device is available in different dimensions and in different sizes. LM-335 is most commonly available in the market due to its unique features including e.g. large temperatur ...
Hey Everyone! I hope you are doing great and having fun with your lives. I am back to give you a daily dose of information so you can grow and progress in your relevant field. Today, I am going to uncover the details on the Introduction to 2n4401. It is an NPN (negative-positive-negative) bipolar junction transistor (BJT) which is used for general purpose amplification and switching purpose. It consists of P doped semiconductor that exists between the two layers of N doped material.
I'll give you a brief detail about this transistor so you don't have to go anywhere for finding the information regarding this transistor. You can also check the Introduction to 2n4402 which is a complementary PNP transistor of this NPN transistor. Let's get started.

Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to TIP32. The TIP32 is a silicon Epitaxial base PNP transistor it exists in a TO-220 malleable casing. It is proposed for use in less power consuming rectilinear and swapping submissions. Its quality is that it exists in three different collector and emitter ratings. Its corresponding NPN transistor is TIP31.
This is a communal transistor it used in diverse engineering projects. It created for minimum time consuming swapping submissions. In today’s post, we will have a look at its fortification, smashup, dissimilarity, claims, etc. I will also share some links where I have connected it with other microcontrollers. You can also get ...
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 ...
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 ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn about the ESP-NOW protocol and how to communicate data between two ESP modules through ESP-NOW protocol and that is too without Wi-Fi connectivity.
What is ESP-NOW Protocol?
Fig. 1: ESP-NOW Protocol
ESP–NOW is a connectionless communication protocol that is used for sharing small data packets between two ESP boards. This protocol is developed by Espressif.
Features of ESP-NOW Protocol:
It is a low-power wireless protocol, which makes two or more ESP devices communicate directly with each other without using Wi-Fi.
ESP-NOW protocol does not require a handshake for establishing a connection but, they require pairing and once the devices are paired they can exchang ...
Hello readers, I hope you all are doing great. Welcome to the 3rd Lecture of Section 2 in the ESP32 Programming Series. In this tutorial, we are going to discuss another important feature of ESP32 i.e. PWM(Pulse Width Modulation).
Pulse Width Modulation is a technique to reduce the voltage by pulsating it. In today's lecture, we will first understand the basic concept of PWM, and after that will design two projects to fully grasp it. In the first project, we will control the brightness of an LED, while in the second one, we will control the speed of a DC Motor.
Here's the video demonstration of PWM Control in ESP32:
Before going forward, let's first have a look at the PWM working:

PWM is used to control the power delivered to the load by pul ...
