Hello everyone! I hope you all will be absolutely and having fun. Today, I am going to give a detailed discussion on Introduction to LM117. Lm 117 is basically a voltage regulator. It is most commonly known as positive (+ve) voltage regulator used to regulate the voltage up to the desired positive level. Lm-117 can regulate the voltage ranging from 12.5V to 37V and provides the current around 1.5A. LM 117 has three (3) pins and is quite easy to use.
To obtain the desired output voltage we need to connect the two external resistors. There are three types of regulations in LM-117 i.e. line regulation, fixed regulation and load regulation. The line regulation & load regulation both are far better than fixed regulation. LM 117 provides overload ...
Hello readers, we hope you all are doing great. Welcome to the 4th lecture of Section 5(ESP32 Sensor) in the ESP32 Programming Series. So far, we have discussed the ESP32 built-in sensors in this section. Today, we are going to interface an external embedded sensor(i.e. PIR Sensor) with the ESP32 Microcontroller board. At the start, we will discuss the basics of a PIR Sensor(HC-SR501) i.e. its pinout and working. After that, we will design a simple project to detect the motion with a PIR sensor and ESP32. Finally, we will display the motion detection results on the ESP32 WebServer.
We will use ESP32 interrupts to detect the motion. Interrupts are used when a microcontroller needs to continuously monitor an event while executing other tasks at the same time. We have already posted a tuto ...
Hi Fellas! Hope you’re doing well today. I welcome you on board. In this post today, I’ll detail the Introduction to 2SD882.
2sd882 is an NPN bipolar junction transistor used for amplification and switching purposes. It is a semiconductor device composed of silicon material and comes in the TO-126 package. As this is a bipolar transistor, here conductivity is carried out by two charge carriers i.e. electrons and holes where electrons are major charge carriers and holes are minority carriers. During the amplification application, the small input current across one pair of terminals is used to produce a large output current across other pairs of terminals.
In this post, I’ll walk you through the working principle, pinout, power ratings, alternat ...
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 ...
Hello friends, hope you all are fine. Today, I am going to share a new Bluetooth Library for Proteus. Using this Library, now you can quite easily use Bluetooth modules in Proteus ISIS. I have designed two Bluetooth modules which are HC-05 and HC-06. We all know about these modules. We use these modules for sending data through Bluetooth. Till now, there's no such Bluetooth Library designed for Proteus and we are the first developers of this awesome Bluetooth Library for Proteus. I hope you guys are gonna like it. I have also posted a tutorial in which I have done Arduino Bluetooth Communication using HC05 in hardware. I hope that one will also be interesting to read, if you have planned to start working on Bluetooth Module.
Other bloggers are wel ...
Hello friends, hope you all are fine and having fun with your lives. In today's post, I am going to share How to do USB Communication between Android and Arduino. I have designed many projects before in which I have interfaced Android and Arduino and communicated between them but in those projects I have used either Wifi or Bluetooth as a mode for communication. But recently I got a project in which I have to do USB Communication between Android and Arduino, they have this restriction of using USB. So, I have to work on it and I got it working successfully. You should also have a look at How to Install Android Studio. and Getting Started with Android.
So, today I thought to share it with you guys. It isn't much difficult but will need a little pa ...
Hi Guys! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to Arduino Esplora.
Looking like a videogame controller, the Arduino Esplora is an electrical device that contains an Arduino Leonardo board (microcontroller) and a number of outputs and inputs. There are a colored LED and a buzzer as outputs. And there is a light sensor, four buttons, a joystick, a microphone, an accelerometer, and a temperature sensor as inputs. In other words, it is just like another Arduino Board with integrated actuators and sensors.
Just stay with me for a little while, as I’m going to document the complete Introduction to Arduino Esplora covering pinout, working, pin description, how it’s different than othe ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to do an Arduino 74HC165 Interfacing and we will have a look at How to increase Input Pins of Arduino. 74HC165 is a shift register and works on the principal of Parallel In Serial Out. In my previous tutorial Arduino 74HC595 Interfacing: Increase Output Pins, we have seen How to increase the output pins of Arduino and today we are gonna do exact the opposite and we will increase the input pins.
74HC165 will take 8 parallel inputs from different sensors or buttons etc and will send them to serial OUT Pin, which will be connected to Arduino. So, if you are working on a project where you want to get data of 15 or 20 digital sensors then you can use this shift register and ...
Hi Friends! Happy to see you here. I welcome you on board. In this post today, I’ll walk you through the Introduction to 1n5821.
The 1n5820 is a Schottky diode that carries high surge capability and low forward drop voltage. It helps in extremely fast switching and comes in the DO-201AD package. This diode is also known as a hot-carrier diode and is well-shielded against the overvoltage, keeping the device safe under desired ratings.
I suggest you read this post all the way through as I’ll discuss the complete Introduction to 1n5821 covering the datasheet, features, pinout, features, and applications.
Before further ado, let’s get started.

Hello readers, I hope you are all doing great. Welcome to the 2nd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. In the previous tutorial, we discussed the built-in ESP32 Hall Effect Sensor. In this tutorial, we will discuss another inbuilt sensor of the ESP32 i.e. Capacitive Touch Sensor.
ESP32 Board has 10 built-in capacitive touch pins, which generate an electrical signal when someone touches these pins. These ESP32 touch pins are normally used to wake up the board from deep sleep mode. These touch pins are also used to replace the normal mechanical buttons with touch pads, improving the presentation of the IoT projects.
Here's the video demonstration of the ESP32 Capacitive Touch Sensor:
Before going forward, let's first understand how this touch sens ...
