Building Various Fun Lighting Projects
Introduction To Lighting Projects
One of the fun electronics projects that one can experiment and build are lighting projects that uses lights. Among the lighting
devices that are popular in recent years are LEDs (Light Emitting Diodes). LED is fast replacing bulbs as the technology
in LED gain breakthough year by year. The luminence of powerful LEDs and the development of various colors of LEDs - in
recent years, blue colour has become a common color. LEDs have been used in household appliances, automobile, control
circuitry and a host of other applications. Other projects include the use of triac as phase control for light dimmers.
Some of the lighting projects that one can build are as listed below.
Two Way Light Switch
Have you ever wonder how a lamp that is used to light up the stairs of a building is connected to the two switches that
controls it from either end? These two way switches have a single pole double throw (SPDT) configuration...
LED Light Flasher Project
This is a simple LED flasher project that uses a CMOS 74C04 Integrated Circuit to alternately ON and OFF two LEDs that are
connected in parallel.
Car LED Light Sequencer Project
This Car LED Light Sequencer uses a standard 74C164 8 bit shift register as its heart of operation. It will turn 8 LEDs ON in sequence. It can be placed in the automobile dash board.
Dice LED Circuit
This project uses 7 LEDs to simulate the rolling of a dice which can be used to replace mechanical dice.
Up/Down Display LED Sequencer
This Up/Down Display LED Sequencer project uses a standard 4514 1 of 16 decoder to turn 16 LEDs ON and OFF in a sequential
order.
LED Flasher Circuit
This is a simple LED flasher project that uses a common 555 timer IC for its operation. It has 2 LEDs that flashes
alternately.
Solid State Penlight LED Project
This solid State Penlight LED Circuit Project is one of the simplest electronic design that one can embarked on.
Lighting Projects Using Light Dependent Resistor(LDR) Circuit
This simple project will trigger a relay ON when the environment is dark to enable a light bulb connected to it turn ON.
Light Dimmer Project
This is a standard 220-240 VAC circuit which can be used to adjust the brightness of mains lights.
Construct a simple VU Meter using LM3915 ICs
This VU (volume-unit) meter is capable of monitoring and displaying power levels present at the speaker terminals of
an stereo audio power amplifier.
Construct a LED Temperature Thermometer
This LED temperature thermometer project will display the room temperature where it is placed using 10 LEDs. LM34 temperature sensor and LM3914 LED driver ICs are used.
Compact Fluorescent Lamp (CFL) Project
The application note provides the design of a CFL (compact fluorescent lamp) that is able to drive a 13W lamp from
110 or 220 VAC input, 34kHz frequency of operation and softstart with cathode preheating.
