Strain Gauge Sensor

Strain Gauge is an electronic component used to measure pressure (deformation or strain). This tool is in the form of metal foil or metal wire that is insulative (insulation) attached to the object to be measured pressure, and the pressure comes from loading. The principle is that if the pressure on the object changes, the foil or wire will be ...

Minimize and Enlarge Image Size

Images are displayed in HTML documents sometimes do not have the same image size to the actual size. To produce images with quality similar to the original, determination of size also becomes important to note. Therefore perbandinganya must match the original size of the image. To determine the size of the image, we need to fill attribute is used to ...

Photo Diode Sensor

Semiconductor photo devices utilize quantum effects on junctions, energies received by electrons that allow electrons to move from the valence tire to the conduction tire under reverse bias conditions. Semiconductor materials such as Germanium (Ge) and Silicon (Si) have 4 valence electrons, each electron in an atom is bonded so that the valence electron is even 8 for each atom, ...

Interruptions Microcontroller

Interruptions are events or events which caused the microcontroller pause to serve these interruptions. Programs that run at airport interrupt the call Interrupt Service Routine (Routine Service Interruptions). The analogy is as follows: a person is typing reports, suddenly the phone rang and interrupted the person so stop typing jobs and picked up the phone after the phone conversation is ...
