ACKNOWLEDGEMENT

We are very pleased to Mr. J. S. Aggarwal, HOD of Electronics & Connection department, to get the help supplied in completing the Major job assigned to us. We all owe each of our thanks to Mr. J. G. Jain, to guide us and solve our problems through the project. Were also grateful to Mr. R. In. Vishnoi friend for his motivation to us to endure this significant project.

Finally, we shell out our sincere thanks and gratitude to Mr. Babulal Sharma sir for making each of our project valuable and fruitful.

We are likewise thankful, for all our co-workers for their co-operation and support. Shobhit Bahri

GOAL

The purpose of the project is usually to make an instrument which should be beneficial to any person who actively works in the lab. It is mainly used to measure voltage, the average of volts and the value of bare minimum & maximum voltage. Consistency measurement is likewise done with great accuracy by about 10Hz to 100k Hz. Every one of the readings are given out by help of audio speakers; therefore , it is a very useful device. It is possibly advantageous for a few person to use this device rather than standard lab equipment.

The programming is done using microcontrollers and different IC's had been used for different purposes that have been defined in the following web pages.

SOURCE OF THE PROJECT IDEA

We got this idea whilst surfing upon net. Additional this thought was prompted by the project guidebook Mr. L. D. Jain sir. As well Mr. R. N. Vishnoi sir likewise helped us with the idea. We thought of the practical advantage of this project, analyzed its uses and came to a realization that this might be advantageous to every person in labs. So this inspired us to work on this kind of project and we tried to produce something successful.

THEORITICAL HISTORY

1 . ATMEGA 32

5

Overview:

The ATmega32 is a low-power CMOS 8-bit microcontroller based on the AVR improved RISC buildings. By executing powerful guidelines in a single clock cycle, the ATmega32 achieves throughputs getting close to 1 MIPS per Megahertz allowing the device designed to enhance power usage versus digesting speed.

The AVR core combines a rich training set with 32 general purpose working signs up. All the 32 registers will be directly connected to the Arithmetic Common sense Unit (ALU), allowing two independent signs up to be seen in one sole instruction accomplished in one clock cycle. The resulting structure is more code efficient while achieving throughputs up to eight times more quickly than regular CISC microcontrollers.

The ATmega32 provides the subsequent features: 32K bytes of In-System Pre-reglable Flash Program memory with Read-While-Write functions, 1024 bytes EEPROM, 2 CARAT byte SRAM, 32 general purpose I/O lines, 32 general purpose working registers, a JTAG interface for Boundary search within, On-chip Debugging support and programming, 3 flexible Timer/Counters with assess modes, Internal and External Interrupts, a serial programmable USART, a byte focused Two-wire Dramon Interface, a great 8-channel, 10-bit ADC with optional differential box input stage with programmable gain (TQFP package only), a programmable Watchdog Timer with Interior Oscillator, an SPI serial port, and six software program selectable electric power saving ways. The Idle mode halts the CPU while allowing the USART, Two-wire program, A/D Ripping tools, SRAM, Timer/Counters, SPI dock, and interrupt system to stay functioning. The Power-down function saves the register material but interrupts the Oscillator, disabling other chip features until the...
