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…
8051 Calculator Circuit Operation As seen at half one has to use the keypad and an LCD with 8051. The keypad consists of rows and columns. When the button is pressed certain keys combined treatment. Pressing 1, column 1 for example is 1.sat nanny and 1-5 should be combined. More than one button in a…
AT89S52 Stepper Motor Control Stepper motor, the motor angular position is changing in steps. This engine is moving into specific steps, according to the windings is controlled by sending signals. Any stimulus that would make my motor movement, the pitch angle is determined. According to the structure of the pitch angle of engine usually 1,…
AT89C51 Scrolling LED Circuit Operation: Keypad’t the values entered the program through is continually monitored, “*” key is pressed unless the display of the first letter that section required all letters appear, but the desired letter or number after it is written “*” key is pressed, the entered character sequence element is recognized as a…
Frequency in all matters relating to the definition based on frequency is required. In the same way the numeric (digital) Frequency frequency to do the same as the description of the circuit should be implemented. Frequency: 1 frequency is called the number of periods per second. Period: a wave of complete rotations made to peryotlu…
Circuit Operation: This practice of over 5 × 7 matrix LED A… Z characters are intended to be created. Provision of characters in source code LEDs (table) was created and when necessary with the help of a function is called. Matrix to be considered a major concern in LED applications, a character created seem to…
An application that performs text printing to the LCD via a microcontroller from a keyboard using the PS/2 protocol. The purpose here is to print text from the keyboard to the Text LCD via the microcontroller. Thanks to the microcontroller inside the keyboard, a code is generated for each key pressed. This code, which is…
