With 8051 DOWN COUNTER The basic principle of this circuit based on the number entered from the keypad is left counting down or up. # On the keypad to make counting down and counting up pressing the * must be pressed to do. 8051 issues must be considered when programming the keypad is detected, the…
Atmel microcontrollers with a good example for the use of DS18B20 DS1302 circuit 2 × 16 LCD display with 4 buttons in circuit adjustments can be made The first button is a long hold in seconds (h) setting switches to the second and third button with the settings is done after the first operation are…
This project is to show the temperature information on a graphic LCD screen using the AT89S52 microcontroller, which DS1620 gives digitally. In addition, it is aimed to notify the user that the ambient temperature increases when the circuit reaches a temperature value above 250C, and a green led lights up when the ambient temperature drops…

So when it comes to 0000 a, b, c, d, e, f, g edu yanmaz.7 segment display LED lights bağlanmıştır.paralel parallel to each other using the same bus to the…
8051 keil example application circuit LCD Display Digital Clock using DS1302 RTC General Information About MicrocontrollersMicrocontroller: It is an electronic element that makes no sense without installing a software. When there is software that controls the microcontroller, it has almost unlimited applications. Microcontrollers have many advantages over microprocessors. For example, when a system with a…
Circuit Operation: Circuit diagram appears in the 0-5 the entered value from the keypad circuit, which is connected to port P1 applied to the integrated DAC 0808 DAC output is obtained from the analog voltage. P0 port is connected to the 7-segment display of the absolute value of the voltage, which is connected to port…
The operation of the thermometer circuit: If I explain the digital thermometer circuit made using the DS1621 temperature sensor. The operation of the circuit is as follows; The numerical value taken from the heat sensor is sent to the microcontroller with the help of serial communication protocol I2C and the microcontroller prints this value to…
Methods Used in Circuit Design After deciding what to do in circuit design, it is necessary to choose or seek the methods that will save the most time and cost the least. Since our age is home to a time when science and technology may be running horses, there are plenty of alternatives in this…
Speed Meter Circuit consists of four parts. These Supply solid floor Sensor sensor, microcontroller and microcontroller solid hexadecimal numbers we obtained from the 7-segment display technology with time code converter solid. Program Keil µVision3 AT89C51 microcontroller. Supply DC 12V working with solids. However, by 7805 we have achieved solid display technology and microcontroller is supplied…
ADC converter Structure: Most of the physical quantities in the outside world are analog values. For example, heat, temperature, weight, humidity, light intensity, sound intensity, etc. They always change analogously. To provide connections of digital systems with the outside world; The measured physical quantities must be converted into numerical values that the digital system can…
