Getting started with labview

Lab-view (Laboratory Virtual Instrument Engineering Workbench) is a graphical programming language that uses icons instead of lines of text to create applications. In contrast to text-based programming languages, where instructions determine the order of program execution, Lab-view uses data flow programming, where the flow of data through the nodes on the block diagram determines the execution order of the VI's and functions. VI's, or virtual...

Smart phone controlled smart car

I built a wireless robotics platform from a cheap R/C car, an 8051 micro-controller with Bluetooth module, and a Processing program running on a micro-controller to control the vehicle. The vehicle is completely controlled by android smart phone which allows very rapid prototyping of the code to tell the vehicle what to do and how to react to the commands from android smart phone via Bluetooth. I’m hoping this is...

LIGHT EMITTING DIODE Interfacing tutorial

        Light Emitting Diodes (LED) is the most commonly used electronic components, generally for display digital states. Typical uses of LED's include alarm devices, timers and confirmation of user input such as a mouse click or keystroke, events etc. LED's are very cheap and easily available in a variety of shape, size and colors.         89C51, which belongs to the family of 8051 series of micro-controllers...

Interfacing Switch and LED with 8051

Interfacing Switch and LED with 8051             This article is meant for beginners in the field of micro-controllers  When I started with micro-controllers as everyone I also need to learn how to interface a switch with micro-controller. A switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from...

Sinking and Sourcing

Difference Between Sinking and Sourcing Sinking and sourcing refer to the type of digital inputs and outputs used. A sinking digital I/O (input/output) provides a ground. A sourcing digital I/O provides a voltage source.  Consider a simple circuit that consists of one digital input connected to a digital output. The circuit needs a voltage source, a ground, and a load. A sourcing digital I/O provides the voltage needed for the circuit....

LED Dot-matrix display

Driver MM5450 A dot-matrix display is a display device used to display information on machines, clocks and many other devices requiring a simple display device of limited resolution. Light emitting diodes aligned in a form of matrix constitute a dot matrix display. Arrangement of the LED's in the matrix pattern is made in either of the two ways: row anode-column cathode or row cathode-column anode. In row anode-column...
