Simple 4 Watt LED Driver Circuit Using IC 338

The IC LM338 as we know is a highly versatile device when it comes to controlling voltages and current levels. Circuit Configuration In the present design, the device is configured in the automatic current control mode. White LEDs specifically need a well dimensioned input, technically the current to these LEDs must be strictly controlled. By connecting its … Read moreSimple 4 Watt LED Driver Circuit Using IC 338

10 LED Simple Roulette Wheel Circuit

A very simple 10 LED roulette wheel circuit is shown here. pressing the button starts the LEDs in a rotational motion (sequencing) at full swing initially, and gradually slows down, until it stops to a particular, randomly selected LED. The randomness of the selection depends upon the time for which the push remains switched ON … Read more10 LED Simple Roulette Wheel Circuit

LED Strobe Light Circuit with Chasing, Flashing Effects

You might be quite familiar with colorful LED strobe lights, and should have seen them pretty commonly in parties and discotheques. Let’s see how we can make one such circuit at home using LEDs. Although these devices use laser light a for the generation of the required strobe effect, using high bright LEDs can also … Read moreLED Strobe Light Circuit with Chasing, Flashing Effects
