Interfacing DHT11 with Raspberry Pi Interfacing DHT11 Temperature and Humidity Sensor with Raspberry Pi

Temperature and Humidity are the most common parameters that are being monitored in any environment. There are tons of sensors to choose from for measuring temperature and humidity, but the most used one is the DHT11 due to its decent measuring range and accuracy. It also works with one pin communication and hence is very easy to interface with Microcontrollers or…

Interface LCD with ESP12 using Shift Register SN74HC595N Interfacing LCD with NodeMCU without using I2C

In this tutorial we will see how to interface NodeMCU with 16x2 LCD without using I2C communication. Here we will interface 16x2 LCD using shift register SN74HC595. We can also interface it even without using any shift register. We will see both kinds of interfacings in this tutorial. Main difference between both interfacings is the number of pins used in NodeMCU.

Digital Alarm Clock using PIC Microcontroller PIC16F877A Microcontroller Based Digital Alarm Clock

The digital Revolution started in 1950 changes all the existing mechanical and analog electronic structures into digital computers. Since the growth of digital electronics has been exponential, today it is almost impossible for a person to resist using any electronic equipment. Starting from the alarm clock that wakes you up and the toaster that serves you breakfast,…

Interfacing RTC Module (DS3231) with PIC micro-controller: Showing Time and Date Interfacing RTC Module (DS3231) with PIC Microcontroller: Digital Clock

Almost all embedded devices are designed to interact with the real world. They act as a bridge to communicate between the digital world and the real world. To make this process easier and efficient, the digital world would sometimes need to keep track of the time of and date of the real world. This way the digital world will know what time/day it is in the real world and can…

Interfacing GPS Module with PIC Microcontroller Interfacing GPS Module with PIC Microcontroller

GPS is the short-form of Global Positioning System. It is a system which provide accurate Altitude, Latitude, Longitude, UTC time and many more information, which are taken from 2, 3, 4 or more satellite. To read data from GPS, we need some Microcontroller and we already interfaced GPS with Arduino and with Raspberry Pi.

We have selected G7020 GPS…

Arduino based Countdown Timer Arduino Countdown Timer

A timer is a type of clock used for the measurement of time intervals. There are two types of timer, one which counts upwards from zero, for the measurement of the elapsed time, called as Stopwatch. And, the second one counts down from a specified time duration provided by the user, generally called as Countdown Timer.

Here, in this tutorial we will…

MPU6050 Gyro Sensor Interfacing with Raspberry Pi MPU6050 Gyro Sensor Interfacing with Raspberry Pi

The MPU6050 sensor has many functions over the single chip. It consists a MEMS accelerometer, a MEMS gyro, and temperature sensor. This module is very accurate while converting analog values to digital because it has a 16bit analog to digital converter hardware for each channel. This module is capable to capture x, y and z channel at the same time. It has an I2C…

Automatic Pet Feeder using Arduino Automatic Pet Feeder using Arduino

We're building an Arduino automatic pet feeder today that feeds your pet automatically at scheduled times. This complete automatic pet feeder project incorporates a DS3231 RTC (Real Time Clock) Module, allowing you to keep track of your pet's eating schedule and properly schedule feeding at specific times. Our tested design is one of the best pet feeders for DIY makers that…

Digital Thermometer using LM35 and 8051 Digital Thermometer using LM35 and 8051 Microcontroller

Sometimes people find it difficult to read temperature from analog thermometer because of fluctuations. So here we are going to build a simple Digital thermometer using 8051 microcontroller in which LM35 sensor is used for measuring the temperature. We have also used LM35 to build digital thermometer using Arduino, NodeMCU, PIC, Raspberry Pi and other microcontrollers.…

Arduino Calculator using 4x4 Keypad Arduino Calculator using 4x4 Keypad

Programming is always fun and Arduino is a wonderful platform if you are just getting started with Embedded programming. In this tutorial we will build our own calculator with Arduino. The values can be sent in through a keypad (4×4 keypad) and result can be viewed on a LCD screen (16×2 Dot-matrix). This calculator could perform simple operations like Addition, Subtraction,…

Raspberry Pi 3 GPS Module Interfacing Tutorial Raspberry Pi GPS Module Interfacing Tutorial

One of the coolest embedded platforms like the Arduino has given makers and DIYers the ability to get location data easily using GPS module and thus build things that rely on location. With the amount of power packed by the Raspberry Pi, it certainly will be quite awesome to build GPS based projects with the same cheap GPS modules and that is the focus of this post. Today in…

Finger Print Based Biometric Voting Machine using Arduino Fingerprint Based Biometric Voting Machine using Arduino

We all are quite familiar with Electronic Voting Machines, where your vote gets registered electronically and you don’t need to use ballot paper to vote in election. Today security is a major concern and it also needs to be ensured that someone can’t vote twice, so this problem can be solved by introducing Finger Print Based Voting, where a person can be authorized based on…
