What is Rotary Encoder and How to Use It with Arduino

A Rotary encoder is an input device which helps the user to interact with a system. It looks more like a Radio potentiometer but it outputs a train of pulses which makes its application unique. When the knob of the Encoder is rotated it rotates in form of small steps which helps it to be used for stepper/Servo motor controlling, navigating through a sequence of menu and Increasing/decreasing the value of a number and much more.

Interfacing HC-05 Bluetooth module with AVR Microcontroller

In this tutorial let us learn How to interface HC-05 Bluetooth Module with AVR ATmega8 microcontroller. We will establish communication between Android mobile and Atmega8 through Bluetooth module which takes place through UART serial communication protocol. In this project we will control a LED using Bluetooth of our smartphone.

PIC16F877A Microcontroller Based Digital Alarm Clock

This alarm clock will have an 16×2 LCD display which will display the current time and set time. We will use few push buttons to set the alarm time whenever required. The current time will be kept in track using the DS3231 RTC module and we will use IIC communication to get these values from the RTC module

TCRT5000 IR Sensor

The TCRT5000 is an IR sensor unit.
It has both a Photodiode and a Phototransistor coupled in its package.
The photo diode has two pins (Anode and Cathode) which can be used to
generate an IR signal. Similarly the Photo transistor also has two pins
(Collector and Emitter) which can be used to read the IR signal that is
reflected back. This sensor can be used to detect the presence of object
or any other reflective surface in front it, also with some level of
programming it can also calculate the distance of the object in front
it. But the distance can only be calculated for short range objects and
is also subjected o environmental disturbance. So if you look for a
sensor to measure distance of an object in front of it you should try
the HC-SR04 Ultrasonic sensor.

Digital Thermometer using a PIC Microcontroller and DS18B20

Generally, the LM35 temperature sensor is used with microcontrollers to measure the temperature because it is cheap and easily available. But LM35 gives analog values and we need to convert them into digital using ADC (Analog to Digital Converter). But today we are using DS18B20 temperature sensor in which we don’t need an ADC conversion to get the temperature. Here we will use PIC Microcontroller with DS18B20 to measure the Temperature.

Interface GPS Module with PIC Microcontroller

Interface GPS Module with PIC Microcontroller

We are going to use G7020 GPS module which is made by U-blox. We will receive Longitude and latitude of a particular position from satellite and will display the same on a 16×2 Character LCD. So here we will interface GPS with PIC16F877A microcontroller by microchip.

EM-18 RFID Reader Module

EM18 RFID Reader is a module which reads the ID information stored in RFID TAGS. This ID information is unique for every TAG which cannot be copied.

EM-18 is used like any other sensor module. First we
choose the mode of communication between MODULE and CONTROLLER. Next we
will program the controller to receive data from module to display.
Next power the system. When a tag is brought near the MODULE it reads
the ID and sends the information to controller. The controller receives
the information and performs action programmed by us.
