Light Activated Switch:
This low cost circuit without relay and transformer uses diac and triac to switch on the AC lamp up to 100 watts. The lamp will be on as soon as the light intensity goes low and will switch off as soon as light intensity becomes high. Light Dependant Resistor is used here to sense the light intensity.
Digital LED Clock:
Using simple CMOS IC`s make this clock which appears like conventional mechanical clock. Sixty LEDs for minutes and twelve for hours placed in circularfashion. Single LED at center to indicate second. Precision crystal clock is used.
Flashing LEDs:
Simple two transistor a stable multi vibrator drives four LEDs each red and green alternatively to give blinking effect.
Running LEDs:
This amazing circuit gives three different running light effects , continuos in forward or reverse direction, stop and run effect, periodical change in forward and reverse direction.
IR Remote Switch:
Infra red remote switch uses IR beam to switch on or off the equipments through relay from 3-4 meter. TIL38/81 transmitter/receiver pair is used. The signal is frequency modulated to avoid effect of the day light or any other light source.
LED Flashers:
The combination of various flashing methods displays variety of flashing LEDs. Blinking, slow on fast off, rapid on slow off, revolving effect, clock wise, anti clock wise revolving are few of them demonstrated in this circuit .
Light Dimmer:
230V AC operated dimmer is useful for controlling light intensity of incandescent lamp up to 100W or speed control of the fan. Diac and triac combination with angle control circuit is used.
Peacock Feather LED Light:
Peacock feather spreading and closing effect is achieved in this circuit by placing 5 rows of 7 LEDs in half circular fashion. Circuit operates in last in first out mode.
Moving LED Display:
This sign board welcomes guests with attractive moving LED display. Letters from the word `WEL-COME` lights up one by one , remains on for a while when all the letters light up and then vanishes. In this way cycle repeats. Cycle time can set.
LED Remote Switch:
Using white LED or torch you can switch on or off relay remotely from 2-3 meter. LDR is used as a light sensing element. A sharp blink of LED switches on the relay and slightly longer duration blink will switch off the relay.
Sun Flower:
This attractive show piece gives effect of blossoming of sun flower as sun rises, proceeds and sets. LDR is used to sense day light intensity. Four circles of LEDs starts illuminating one by one in morning and start vanishing in the afternoon.
Street Light Controller:
This street light controller switches on light as the sun sets and dark and switches off the light when sun rises. Here photo transistor is used as a light sensor.
AC Flashing Lamp:
This operation theater AC lamp flashes at the rate of one pulse per second. It directly operates from 230VAC. Transistorized a stable multi vibrator with SCR power circuit is used. Low power zero watt incandescent lamp is connected.
LED Direction Indicator:
This attractive LED lighting arrays can be used as a direction indicator. Single IC CD 4093 quad NAND gates is used.
Pendulum:
In this circuit ten LEDs are arrange in half circular manner that gives very attractive effect of pendulum as they move to and fro. The speed is adjustable.
Emergency LED Lamp:
Simple but useful lamp in case of power failure. It switches on automatically when electricity failed. Operates on 9V battery.
PIR Light Controller:
Light will be on when PIR senses existence of the human being. Time delay is provided to switch off the light after exit of the man.
