LED CUBE



Multiplexing
How to control 64 LEDs without using 64 individual wires? Multiplexing!
Running a wire to the anode of each led would obviously be impractical, and would look really bad.
One way to get around this, is to split the cube into 4 layers of 16x16 LEDs.
All the LEDs aligned in a vertical column share a common anode (+).
All the LEDs on a horizontal layer share a common cathode (-).
Now if i want to light up the LED in the upper left corner in the back (0,0, ....etc

blinking a led using 8051 ppt

This is the first project regarding 8051 and of course one of the simplest, blinking LED using 8051. The microcontroller used here is AT89S51 In the circuit, push button switch S1, capacitor C3 and resistor R3 forms the reset circuitry. When S1 is pressed, voltage at the reset pin (pin9) goes high and this resets the chip. C1, C2 and X1 are related to the on chip oscillator which produces the required clock frequency. P1.0 (pin1) is selected as the output pin. When P1.o goes high the transistor Q1 is forward biase ....etc

I feel as though there are many individuals on this site who haven't had the opportunity to see what our customers are doing with our products . I know browsing through thread after thread to see results can be daunting, so I've gone ahead and collected photos from many various grow demonstrations that are either completed, near completion, or in progress to show you that the future of lighting technology is here!

It is intended for a robot to make music. By a device on a midi port on a PC connected to actions of a robot measured and read. These actions through the program MAX on the PC used to combine music samples. The software also provides output signals that can be generated, possibly back to the robot can be sent. The climbing robot, in the lab, it will be used to generate signals. Existing systems are similar miditron and i-cube. ....etc

This Project is very simple and when completed, causes a light-emitting diode (LED) to flash or pulse alternately on and off at a very slow rate, that is, at a low frequency. It could be used as a dummy car alarm indicator. You sometimes see these tiny pulsating lights in expensive cars protected by sophisticated car security systems, warning you that the car alarm is armed and ready.
For this design, the LED flashes on for a brief period and stays off for a relatively longer period. Because additional current is consumed from the battery ever ....etc
