how does the auto dialer works.PLZ HELP TO MAKE THE PROGRAM BASED ON MICROCONTROLLER.
Measuring strain using micro-controller is simple and easy. When measuring using micro-controller you use points and condensers.
How data encrypt and decrypt from PC to PC using micro controller?
how temperature is measured using 8051 micro-controler?
yes
yes
because in atmel .............it is easy to program and troubleshooting
By using buffer along with micro-controller, it is possible to reduce the effect of 'back EMF' or 'Spiking Effect'. The capacity of any micro-controller is to sink or source current up to 25mA and its ports gets damaged if it is more. So buffer protects ports of micro-controller getting damaged. And it is possible to get appropriate data trans-receiving by using buffer in micro-controller.Sachin Joshi
Yes.
Microcontroller have inbuilt memory, interrupts, etc. Which you will need to connect externally in microprocessor. Thus, Microcontroller is better than microprocessors
Any controller used in motors or electrical drives are only to get variable speed or variable torque or to get higher efficiency. The controller can be anything, it might be micro controller or it can be DSP controller or may be other. But DSP controller finds some advantages over micro controller. Both the controllers are Digital controllers only, but DSP controller has inbuilt Analog to Digital converter, inbuilt Digital to analog converter , inbuilt counter and inbuilt pulse generator. With a micro controller we need to assemble all the above converters, counters and pulse generators externally, so DSP based electrical drives are more popular though the cost is more compared to micro controllers.
One of the least important considerations at the beginning of an automation project is the micro-controller. There are a wide range of them available and they offer a vast array of functionality. The major manufacturers of micro-controllers offer tiny 8 pin devices through 100 pin ICs that have a remarkable set of functions. Before thinking about the micro-controller to use, it is vital that the functional specification of the final product is considered. Without that specification, choosing a micro-controller is nothing more than guess work.
Yes, using a power dialer is completely legal. Power dialers are mainly used by the many big companies. They use the power dialers for the sales process.
