The tv oscilloscope is undoubtedly one of the basic instrumentation in electrical engineering. Oscilloscopes are available in two basic designs – analog and digital. Amateur analog oscilloscope design is relatively complex and expensive, while the construction of the digital oscilloscope is due to the availability of microcontrollers much easier. One of the basic elements of each oscilloscope’s display unit. For analog oscilloscopes can be found with osciloskopickými screens. Modern digital oscilloscopes use different displays, which are often very expensive. Therefore, some structures conceived as modules that can be connected to a computer. Data is then displayed using the software installed on the computer monitor.

TV OSCILLOSCOPE PROJECT

Most digital oscilloscopes consists of a fast AD converter, memory FISO1 and control circuit. This concept is a proven standard, availability-based components allows these units to include single components – a microcontroller. The advantage of this solution is its simplicity and low cost, the disadvantage is the lower sampling frequency oscilloscope. Since the aim was to create a structure oscilloscope, enabling measurement of low frequency frequencies can accept this limitation. The result is an audio oscilloscope that can capture signals with a sampling frequency of 500 kHz.

8051 microcontroller distance measurement using ultrasonic transceiver done. Studies, using microcontrollers 8051 with the help of ultrasonic distance measurement includes the transceiver. A system ultrasonic transceivers, LCD et al 8051 microcontroller is used.

Before initiating operation of the system used in the system of the working principle of the ultrasonic transceiver is deemed useful to give a brief. authors :Murat FETTAHOGLU Faruk YILDIRIM

SRF04 ULTRASONIC TRANSCEIVER

To a distance of 10.7 meters maximum results. Has a low current consumption. Minimum sensitivity distance is 26cm. Is preferred because the smaller size modules.

SRF04 ‘front side of Figure 2 are given in. As shown in Figure 4 has the port. Among them, 2 percent supply (+5 V), the other two pulse outputs (pulse echo output) and

SRF04 TIMING DIAGRAM

Srf04 The working principle is briefly as follows: SRF04 ‘reputation minimum 10us to start working a trigger pulse as shown in the diagram SRF04’ reputation is applied to the trigger input. After applying these pulses SRF04 sends out ultrasonic waves and generates.

340metre/sani is known that the speed of sound in air, bounced off the surface of these sound waves are sent back period is calculated. This period is known, the sound velocity on the basis of the calculated distance from the apparatus body.

If done the calculations, pulse output from the pulse duration in the availability USN 58 ‘E division (cm = usn/58) can be calculated in centimeters away. If 18ms from If no pulse is produced on a larger object is detected, the output value of 36msn SRF04 again to drop to 0 volts level.

Adc 0831 with 8051 lm 35 temperature sensor, and a detailed project examples for the use of inverters. author :Özer Deniz

Objective: LM 35 temperature sensor dealt with 0831 ADC analog-to-digital conversion of knowledge, and expression of this information as the temperature on the LCD display.

Abstract: In our program; 8-bit temperature data from ADCs continuously scanned and converted into ASCII code is displayed on the LCD. Ambient temperature monitoring any change LM35 temperature sensor and the voltage at the output of digital information at the output of the ADC is displaced.

8051 TEMPERATURE CONTROL

Methods: ADC0831 series 8-bit output, which is an analog-digital converter to receive data sent to the ADC has produced eight clock pulses. After each clock pulse information received from the serial output of the ADC batteries and accumulators given to the low-valent a bit shifted to the left.

Thus, at the end of a loop 8 clock’luk desired digital information is stored in the accumulator. ADC must be switched off after every 8 clock’luk cycle and should be ready to receive a new 8-bit data. For this, the ADC’s CS ‘end of cycle beginning “low”, at the end of the cycle “high” was made.

ATMEGA32 ATMEL WEB SERVER

The web server is an experimental project. It is intended to show what else goes with a simple controller and an old network card. Of course, this can not be a full-fledged server due to limited resources. With us the corresponding functions will operate satisfactorily, but is no guarantee that it works flawlessly with others. For example, the TCP / IP stack is implemented only partially.

The ISA-Ctrl board has an ISA slot for receiving an NE2000 compatible network card. Are supported with RTL8019 chip or 3C5x9 currently NICs. When using a chip 3C5x9 a small Anpasung the circuit board is necessary You have to use an ISA slot not mandatory! The slot consists of a 2×31 and a 2×18 pin pin socket. When the 2x18er on the board times hard look at you will notice that only two pins are used. These are +5 V and GND. These are (for all my available network cards) already bridged to the NIC for 2×31 pin connector. This means that you can save in this case, the smaller socket. A 2×31 pin connector can be found easily at Reichelt …
