We are offering led panel boards. Vilambara range of led display boards are highly versatile. Having various choices in color and size. All of them are having computer connectivity, memory, scheduling feature and enormous effects to make the messages most attractive. It is ideal for indoor semi-outdoor applications. Vilambara can be used as information & advertisement display board in schools, colleges, universities, hotels, hospitals, shops, malls, theatres and offices. lakshya � means destination. To make the name apt, lakshya is a high quality led display board, that can be used as destination display boards in transport buses. Its wide viewing angle, ample viewing distance, adjustable brightness, weather-proof design and multi-lingual capabilities make it the ideal companion for buses. Multiple routs can be loaded in its memory and driver can select the necessary one easily. It can be interfaced with integrated transport system (its) for the new generation buses. There are different sizes of lakshya available, meant for front, side and rear of the buses. Also there is an indoor led board to display �next stop� to the passengers inside. This board can be controlled either automatically by a gps device or manually by the driver.

  Dancing LED Using 555 DIY Kits (Not Soldered) Astable Multivibrator circuit is a simple multivibrator which has no stable state. It has two LED, which will flashing with a time period. NE555 oscillator is used for generating the free running waveforms whose output will be adjustable by varying the external RC network. NE555 is a Timer IC, which is connected in an astable multivibrator mode. In NE555, 8th pin & 1st pin is connected to Vcc & Ground. The 4th pin is Reset pin which is active low and is connected to Vcc to avoid accidental resets. 5th pin is the Control Voltage pin which is not used, so to avoid high frequency noises it is connected to a capacitor C2 whose other end is connected to ground. Usually C2 = 0.01μF. The Trigger (pin 2) and Threshold (pin 6) inputs are connected to the capacitor C1 which determines the output of the timer. 2nd & 6th Pin are connected together allowing the circuit to re-trigger itself. During each cycle, capacitor C1 charges up through both timing resistors, R1 and R2 but discharges itself only through resistor, R2 as the other side of R2 is connected to the discharge terminal, pin 7. Finally circuit works as a free running multivibrator. It has astable outputs (Pin 3). Diode 1N4007 is used for preventing the negative voltages while discharging the Capacitor C1. In Output, If LED1 is ON then LED2 is OFF and vice versa.            t1=0.693(R1+R2)C1      (Capacitor charging time)                      t2=0.693R2C1        (Capacitor discharging time)                           T=t1+t2         (Total time period)
