Hall sensors are sensors which produces an electrical signal at its output when it comes in contact with a magnetic field. The analog value of the electric signal at the output of the sensor is a function of the strength of the magnetic field. Hall sensors are everywhere these days, they are being used for different reasons and in all kind of devices from mobile phones…
The main usage of the Relay was seen in the history of transmitting and receiving the information, that was called as Morse code where the input signals used to be either 1 or 0, these change in signals were mechanically noted in terms of ON and OFF of a light bulb or a beep sound, it means those pulses of 1s and 0s are converted as mechanical ON and OFF using…
Transistors are the semiconductor devices used for switching or amplifying electrical signals. They are highly durable, smaller in size and operates on a low voltage supply. A Transistor is a three terminal device:
Base: This pin used for activating the transistor (minimum 0.7V required to turn ON a Transistor) Collector: Current flow through…
The MSP-EXP430G2 is a Development Tool a.k.a LaunchPad provided by the Texas Instruments to learn and practice on how to use their Microcontrollers. This board falls under the MSP430 Value Line category where we can program all the MSP430 series Microcontrollers. Learning how to use TI Microcontrollers would definitely be a mighty tool up in our…
In this tutorial we are going to interface a DC motor to Arduino UNO and control it's speed using PWM (Pulse Width Modulation) concept. This feature is enabled in UNO to get variable voltage over constant voltage. The method of PWM is explained here; consider a simple circuit as shown in figure. This tutorial uses the L293D IC, we have also built a DC motor speed…
Have you ever feel a shock by touching the switch? It does not generally happen but sometimes physical contact with switches may be dangerous. But what if the switch gets wireless and you don’t have to press any button at all for switching on or off your home appliances. So today we are building a Simple Wireless Switch Circuit in which there is no need of physical contact…
In this project we are going to build a Digital Voltmeter without using any microcontroller. Here we are using a very popular IC for voltage measurement namely ICL7107/CS7107. Using ICL7107, we can build accurate and very low cost voltmeter. ICL7107 is a 3.5 digit analog to digital converter (ADC) which consumes very low power. The IC has internal circuit for driving…
We all are familiar with dice and often played LUDO or SANP SIDI (Snake & Ladders) game by using dice. Dice is a squire type solid box which contains 6 different numbers on all of its sides. We throw dice on a surface to get a random number while playing the games. In this project we have tried to replicate it with a digital dice using arduino uno board. In place of…
In this tutorial we will learn about Servo Motor and How to interface Servo with MSP430. The MSP-EXP430G2 is a Development Tool a.k.a LaunchPad provided by the Texas Instruments to learn and practice on how to use their Microcontrollers. This board falls under the MSP430 Value Line category where we can program all the MSP430 series Microcontrollers…
Servo motors are basically rotary actuators that enable precise control of angular position, acceleration and velocity in various embedded system applications. Commonly having a rotation limit of 90o to 180o, servo motors are DC motors equipped with servo mechanism to sense and control angular position. They are used where there is a need for accurate shaft movement or…
GSM module is used in many communication devices which are based on GSM (Global System for Mobile Communications) technology. It is used to interact with GSM network using a computer. GSM module only understands AT commands, and can respond accordingly. The most basic command is “AT”, if GSM respond OK then it is working good otherwise it respond with “ERROR”. There are…
The interfacing of a 16x2 LCD display with 8051 microcontroller is very popular and one of the most important in embedded systems programming. This tutorial will explain the complete LCD interfacing of 8051 C program, circuit connections, and coding strategies in a program with the use of the AT89S52 microcontroller.
The display units are the most important output devices in embedded…
