Brushless motors have much more satisfying results as compared to brushed motors. The basic difference between them is that in a brushless motor, the rotor itself contains the permanent magnets and the electromagnets move to the stator which is quite opposite as seen in a brushed motors. It’s more precise and can also factor the speed of the motor into the equation. This makes brushless motors more efficient. There is no sparking and much less electrical noise. There are no brushes to wear out. With the electromagnets on the stator, they are very easy to cool. You can have a lot of electromagnets on the stator for more precise control. The only disadvantage of a brushless motor is its higher initial cost, but you can often recover that cost through the greater efficiency over the life of the motor.

This project makes use of three out of the eight ADCs present in AtMega16 IC to display the corresponding digital data of X, Y and Z outputs of an accelerometer on 16X2 LCD.It’s very easy to deal with such kind of modules as they just need the VCC and GND supply to get started, rest it is its job to provide us the analog data.These modules work on simple concept like that of force acting on an object at inclined plane. It deals with the Mg(sin ?) and Mg(cos ?) part of the force and calculate the angle ? for further calculations. Now it also notices the change in force from which acceleration will be calculated.

In today’s secure world biometric safety is on the top. Unlike other techniques which make use of passwords and numbers, that are needed to be remembered, biometric techniques make use of human body parts like fingerprints or even iris of your eyes and as we know that these things are unique to all thus it makes biometric systems the most effective over others. In this project I have interfaced a very popular fingerprint scanner R305 with AtMega 16 microcontroller. This module communicates over UART protocol with microcontroller i.e. it makes use of Rx and Tx pin of microcontroller to interact with it.

您是否想知道用自己的手机操作玩具车？是的，我做了这样的事情。该项目涉及您的手机和汽车之间的通信。在这里，我使用了手机的内部加速度计来操作玩具车。该系统通过蓝牙界面无线通信，因此我们需要具有蓝牙兼容性的手机。此外，我已经为同一任务提出了Android申请，因此手机必须具有Android操作系统J

省电是国内和工业单位的主要关注点。我们总是努力通过多种方式节省电力来减少电费，但是由于某些已知且无法预料的情况，我们的努力通常不会转变为节省电力。Adding to our woes we may at times forget to switch off electrical gadgets when we are not using them, especially the AC’s, which not only results in mounting electricity bills, but also forget the fact that we are wasting a resource which is of National Importance.

The circuit presented here demonstrates how to generate Audible Frequency from an AVR Microcontroller. The output of Microcontroller is always digital so to generate audible sound at the outset first it needs to be converted into Analog. A DAC (Digital to Analog Converter) is used for this purpose. Microcontroller generates sine wave of Audible Frequency using DAC. This sine wave is further given to Audio Amplifier that drives speaker. Microcontroller generates sine wave of fix frequency continuously. So we can hear an audible tone of fix frequency

Are you an electronic hobbyist? Then an adjustable power supply is a must for your various needs. This project explains how to make a LM317 based adjustable power supply unit with a digital display

Electricity is the most required and important element of human life. We cannot imagine our day to day life without electricity. Electricity is generated using conventional (coal, diesel) and non conventional (water, wind, sunlight) energy sources. The recent and latest trend is to generate electricity from solar energy. The solar panel (made up of solar-photovoltaic cells) converts solar energy in to electrical

尽管机器人的外观和功能差异很大，但所有机器人都在某种形式的控制下共享机械，可移动的结构的特征。机器人的控制涉及三个遥远的阶段：感知，处理，动作。通常，受体是安装在机器人上的传感器，处理是由机上微控制器完成的，并且该任务是使用电动机或其他某些执行器执行的。在项目中，Pick and Place Robot由手机控制，该机器人由手机控制，该手机拨打呼叫到附上机器人的手机。在通话过程中，如果按下任何按钮，则在另一端听到与按下按钮相对应的音调，称为“双音多频率”（DTMF）音调。机器人在机器人中堆叠的电话的帮助收到了这些音调。在DTMF解码器IC MT8870的帮助下，MicroController处理接收的音调。这些IC向电动机驱动器IC L293D发送信号，该信号将电动机向前，反向，左，右，拾音，释放，向上，向左，向左旋转，向右旋转，向前驱动电动机。

Did you know that most of the thefts at home happen when it is empty? But not everyone is rich enough to hire a security for their house and at the same time they themselves cannot be at home 24 by7. Now what if there is a system which alerts you about an intruder through a text message?The following tutorial teaches how to make you own intruder alerting system

In many of the applications it is required to alter the direction of DC motor instantly. Like in washing machine, mixer, drilling machine winding – rewinding machine etc. Changing the direction of DC motor using joystick is most suitable and handy method.In industries the joystick control is most preferable way to control machinery that is operated with DC motor. The best example is 3 axis or 2 axis DC motor operated crane. In this, 3 (or 2) DC motors moves crane up or down, rotate it left or right using 3 (or 2) joysticks

现在，LED灯泡越来越受欢迎，因为它们具有多个优势。他们的某些优势在下面列出·他们的能量（电气）消费要少得多·亮度更多·如果使用LED灯来代替常规灯，则它们的强度可能会变化。导致节省常规能源（例如煤炭，汽油，柴油）等的电能。DEL的光强度也可以按照环境光进行变化。这是节省电能的又一个加点。我们可以将光强度设置为所需水平，并获得具有精确量的发光和节省能量的双重优势。

我们可以计算这类应用程序的数量re is a need to change direction and/or speed of DC motor. The direction of DC motor can be controlled by just reversing the polarity of given supply. And for varying speed, there are various ways to vary speed of DC motor but the best amongst them is PWM – pulse width modulation technique. In this technique we shall vary the width of applied pulse that will vary average voltage applied to motor and its speed will change.

以前在10到15年之前大部分的加热器trical lights were either light bulbs (with yellow light) or tube-light sticks (with white light). The major disadvantage of these lighting devices was they consume more electrical energy (in terms of Watt) and gives less luminance (brightness). Light bulb wastes their most of the energy in form of heat. Also the life time of such devices was also short. Next comes compact fluorescent light (CFL) bulbs. They consume much less electrical energy than light bulbs and tube-light sticks and give more light. But their disadvantage is their intensity cannot be varied. Also their life time is limited to few thousand hours. But because their energy consumption is very less compare to light bulbs, they almost replace them.Now a days LED light bulbs are becoming more and more popular because they have several advantages over light bulbs and CFL bulbs. Some of their advantages are listed below

In many application of controlling robotic gadget itbecomes quite hard and complicated when there comes the part of controlling it with remote or many different switches.Mostly in military application, industrial robotics, construction vehicles in civil side, medical application for surgery. In this field it is quite complicated to control the robot or particular machine with remote or switches, sometime the operator may get confused in the switches and button itself, so a new concept is introduced to control the machine with the movement of hand which will simultaneously control the movement of robot.
