Automatic Dualoutput Display



This circuit lights up ten bulbs
sequentially, first in one direction
and then in the opposite direction,
thus presenting a nice visual effect.
In this circuit, gates N1 and N2 form
an oscillator. The output of this oscillator
is used as a clock for BCD up/down counter
CD4510 (IC2).
Depending on the logic state at its
pin 10, the counter counts up or down.
During count up operation, pin 7 of IC2
outputs an active low pulse on ....etc

I have seen a topic called Automatic Room Light Controller here.But i'm aiming to control a Fan too in addition to the light.I'm not using microcontroller in my circuit,since i'm poor in programming. I'm using 2 LDRs at the door to sense entry or leaving people.i got 2 circuits using LDR. One contains 4 quad opamps LM324,logic gates and 2 decade counter CD4017(for counter)as main parts while the other includes NE555 timer too.Igot the former circuit from E4U februa ....etc

AUTOMATIC NIGHT LAMP WITH MORNING ALARM
ABSTRACT:
Automatic Night Lamp with Morning Alarm System is a simple yet powerful concept, which uses transistor as a switch. By using this system manual works are 100% removed. It automatically switches ON lights when the sunlight goes below the visible region of our eyes. This is done by a sensor called Light Dependant Resistor (LDR) which senses the light actually like our eyes. It automatically switches OFF lights ....etc

Introduction
This circuit automatically turns on a night lamp when bedroom light is switched off. The lamp remains ‘on’ until the light sensor senses daylight in the morning. A super-bright white LED is used as the night lamp. It gives bright and cool light in the room. When the sensor detects the daylight in the morning, a melodious morning alarm sounds.
The circuit is powered from a standard 0-9V transformer. Diodes D1 through D4 rectify the AC voltage and the resulting DC voltage is smoothed ....etc
