Hello everyone! I hope you all will be absolutely fine and having fun. Today, we are going to work on Arduino Keypad Interfacing. First of all, I would like to tell you a bit about the keypad. After getting the basic idea about the keypad, we will start our discussion about Arduino Keypad Interfacing. You should also have a look at Interfacing of Keypad with PIC Microcontroller.
In this tutorial, I am going to use a 4×4 keypad. It has sixteen buttons having four alphabetic characters. Let's have a look at the Arduino Keypad Interfacing:
What is Keypad?
The keypad consists of multiple buttons, arranged in the form of a matrix(rows & columns) and is used in embedded projects.
They are cost-efficient and are easily available from online el ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to LM380. LM-380 is an audio amplifier, specially designed for the customer's power audio amplification purposes. Its designers fix its gain internally up to 34dB. In LM 380, ground reference signal is allowed by a unique input stage and the output automatically maintains its level to half of the supplied input voltage.
LM-380 has a copper lead frame. The three pins in the middle of the IC on both side, are basically the ground pins. These three pins on both sides makes it easy for the user to use this device for standard PC's. LM 380 has several different features e.g. wide supply voltage range, high peak current, lo ...
Hello friends, I hope you all are doing great. In today's tutorial, we are going to design a Proteus Simulation for Automatic Plant Watering System using Arduino. We have designed this project for engineering students as it's a common semester project, especially in electrical, electronics and mechatronics engineering.
The two most significant hazards to the agriculture industry are the need for extensive labor and a scarcity of water. According to the World Wildlife Fund (WWF) organization, water shortages might affect two-thirds of the world's population by 2025, putting both the ecosystem and human health at risk. The use of automatic plant watering systems eliminates both of these problems by watering plants at specified times and amounts whil ...

Hi Friends! We always feel happy when you come over to watch useful information that resonates with your needs and expectations. I am back to give you a daily dose of information so you can excel and grow in your relevant field. Today, I am going to unlock the details on the Introduction to 2n5088. It is an NPN (negative-positive-negative) bipolar junction silicon transistor which is specially designed for small signal, high speed, general purpose switching applications. I'll discuss each and everything related to this transistor so you don't need to go anywhere and find all information in one place. Let's hop on the board and explore what is it about and what are its main applications?

Hey Guys! Hope you are doing well. Today, I'll discuss the detailed Introduction to Arduino IDE, where IDE stands for Integrated Development Environment - An official software introduced by Arduino.cc, that is mainly used for writing, compiling and uploading the code in almost all Arduino modules/boards. Arduino IDE is open-source software and is easily available to download & install from Arduino's Official Site.
In this post, I'll take you through the brief Introduction of the Software, how you can install it, and make it ready for your required Arduino module. Let's dive in and get down to the nitty-gritty of this Software.

Hello Friends, i hope you all are fine and enjoying. Now i am going to share my new project tutorial which is Traffic Signal Control using 555 Timer. Up till now i have uploaded a no. of projects using 555 timer and i have got much appreciation from my friends, for some 555 timer based projects like How to use Capacitive Touch Sensor in Proteus ISIS, Sequential LED Blinking using 555 Timer and many more.
Now i am going to share another application of 555 Timer and here we will be using a shift register (4017) next to 555 timer to implement Traffic Signal Control circuit. 4017 is a SERIAL IN PARALLEL OUT shift register. Data enters in a serial manner into register and it leaves the register in parallel manner. 4017 is a 10-bit shift register and it ...
Hello friends, I hope you all are doing great and having fun in your lives. In today's tutorial, we are gonna design a Heart Beat Monitor using Arduino in Proteus ISIS. You should download this Heart Beat Sensor Library V2.0 for Proteus because we are gonna use that to detect heart beat in Proteus.
I have also used a 20x4 LCD which will display our heart rate value. You should download this New LCD Library for Proteus. I have counted the heart beat for ten seconds and then I have multiplied it with 6 to get the heartbeat per minute which is abbreviated as bpm (beats per minute). So, let's get started with Heart Beat Monitor using Arduino in Proteus ISIS.

Hello everyone! I hope you all will be absolutely fine and having fun. I am going to give you the detailed discussion about Introduction to UC3843 today. UC 843 is basically a current mode Pulse Width Modulation (PWM) controller having fixed frequency. It is basically designed for DC to DC converter purposes as well as off line applications and it requires minimum external components. UC-3843 has three different packages which will be explained later.
UC-3843 has several different features which make it ideal and useful for a lot of real life applications. These features may include trimmed oscillator for the control of accurate duty cycle, high gain amplifier and to control power MOSFET, there is a high current totem-pole output. Moreover, some ...
Hello Friends, I hope you all are fine and will be doing well in your life. In today's tutorial, I am going to give you a detailed Introduction to DHT11. It is an embedded sensor used to measure temperature & humidity in the surroundings and gives calibrated digital output. It can measure temperature in the range of 0°C to 50°C with ±2°C accuracy. Its humidity range is from 20% to 80% with ±5% accuracy. It is a small, low cost and easy-to-interface embedded sensor.
