Potentiometer Sensor Function

The transducer / potentiometric sensor is an electromechanical device containing a resistance element connected by a movable slide contact. The sliding contact movement produces a linear, logarithmic, exponential change of resistance, and so on, depending on the way in which the resistance wire is rolled. Potentiometers available on the market consist of several types, namely carbon potentiometers, wire wound potentiometers ...

Microcomputer Architecture

Microprocessors can not stand alone components to process the data, perform calculations, requires other components, so-called system microprocessor or microcomputer. The microcomputer architecture can be seen in the image below: Figure 2 Architecture microcomputers Microprocessor / CPU Microprocessor or CPU is the “brain” which is the main control of all operations in the computer system. Microprocessor taking the binary instructions ...

Photo Transistor Sensor

Photo transistor is a type of transistor whose base bias is infrared light. The amount of current flowing between the collector and the emitter is proportional to the intensity of light received by the photo transistor. Photo transistors are often used as an infrared light control switch, which utilizes saturation (saturation) and off (cut off) conditions from the photo transistor. ...

Memori dan Port Mikroprosesor

Memori adalah komponen yang digunakan untuk menyimpan instruksi-instruksi biner yang akan dijalankan oleh mikroprosesor, serta data yang digunakan untuk bekerja. Memori yang dapat langsung diakses oleh mikroprosesor, yaitu RAM (random access memory) yang dapat dibaca-tulis dan ROM (read only memory) yang hanya dapat dibaca saja. RAM merupakan suatu chip di luar dari mikroprosesar yang berupa memori yang sifatnya sementara dan ...

Aplikasi Rotary Potentiometer

Contoh 1. Misalkan saat wiper berada di atas output (gambar 2.4) yang dihasilkan 10V yaitu pada sudut 350°, sedangkan saat wiper ditengah menghasilkan output 5 V yaitu pada sudut 175°. Maka berapakah tegangan yang dihasilkan pada saat wiper menunjukkan sudut 82° Jawab: Tegangan yang dihasilkan pada sudut 82°=82°x (10 V/350°) = 2,34 Vdc Gambar Potensiometer sebagai alat ukur posisi Potensiometer ...

Microcontroller Interface with LED and Rele

Connect the parallel port with LED General configuration for connecting an LED to a microcontroller is as shown in Figure 1:21 (a) LED lights up when the pin microcontroller given sinya LOW and will die when the pin microcontroller is HIGH. Prisoners are mounted on angkaian used to limit the current flowing through the LED. Resistance value is determined by ...
