Hi Hari,

Nice block diagram, now please tell us what kind of help you need? Have you made the hardware? Do you have a circuit diagram?

[HARI]

i have circuit diagram which is as follows. i want to design it with the help of development board . i want to know whether it is possible or not moreover i need information where to buy all the components online

thank you

the board what iam thinking to use is in above fig plz suggest whether it fits my requirement

the properties of board are

 

• The board is built on a high quality FR-4(1.6 mm) PCB with a green solder mask and a clear and legible white legend. All IO pins are labelled with their names along with any dual feature they support. This greatly simplifies prototyping.
• Onboard USB to Serial converter for serial communication and programming over USB
• Onboard 16×2 LCD support
• Onboard RS232 interface circuit for easy communication with a computer and other serial devices (GPS modules, GSM Modems, etc)
• DC plug-in jack for power input
• Onboard bridge rectifier enables the board to accept both AC and DC input voltages
• Onboard 5V regulator(LM7805) with filtering capacitors and heatsink
• Power Status LED(Green) and 4 x general purpose user LED(Red) and Switches
• Onboard quartz crystal 11.0592 Mhz oscillator circuit
• Port extensions for all ports with detailed pin labeling for easy identification of pins
• External pull-up resistors for Port 0
• Vin, 5V and Gnd bus provided for easy and simple expansion
• The package includes a CD and product manual

The project is possible. Thanks for sharing this much information. But I wonder why you haven’t post the name or part numebr of the board. That’s what we expect.

Also share us how do you calculate the enery consumed?

Hi,

Where is your code, and what kind of help do you need with it?

[sahil]

hyee i wat to do a similar project for my final year i want to write the code in c language i understand the concept of project but i am not able to get a head start.

can any one give a little guidance as in which direction should i proceed. a little example of the code would help a lot thanku.

Hi,

 

Its very easy one.

 

You need following things.

1. Current Sensor

2. Controller 

3. ADC (controller with ADC like ARM7 will be useful)

4. Transformers

5. ZERO CROSSING DETECTORS

hello can anyone help me with the code to design an rfid based prepaid electricity system source code in c . i am working on it using atmega 8. its urgent ..!!

thanks in advance

 

[SHAH DISHANT H.]

Hi,

 

I have just finished this project on ARM7.

Its really amazing one. If anyone wants it, I can provide complete detail.

[vinayak]

yeah dat wud be a great help though mine is on atmega8 so if you can provide info as per it wud b good

 

[SHAH DISHANT H.]

Hi,

 

I have done that using ARM7. First let me know how much you have done till now. I will guide you accordingly.

Mail me details on [email protected]
