Circuit Diagram Need of IC 4049 for LED torch Circuit: As we know it is impossible to glow three white LEDs in series with full brightness using 5v/20mA directly, if we connect the LEDs in parallel ...

Two strips of LEDs fading in a complementary manner, 9V Battery-operated portable unit This circuit operates two LED strips in pulsing mode, i.e. one LED strip goes from off state, lights up gradually ...

If LED is powered directly form a suitable power source, without an LED Driver circuit, in most cases the LED will pump in more current than it could handle and it eventually get destroyed.

Christmas lights in the shape of a star To obtain the best effect with the combination of red and green LEDs, mount them alternately on the PCB board. Exercise care so that you do not accidentally ...

Learn how to use logic gates and circuit diagrams to create a simple calculator that can perform addition and subtraction with four-bit numbers.

This versatile LED display circuit uses an erasable programmable read-only memory (EPROM) to display various light patterns on LEDs. Since bicolour LEDs (comprising green and red LEDs) have been used, ...

One of the simplest play dough sculptures you can illuminate with multiple LEDs is a parallel circuit that looks like a target. Start by rolling out a long 'worm' or 'snake' of non conducting play ...

In a real circuit with more efficient wiring (play dough, while amazing is probably not the best way to carry electricity) you can see differences in how LEDs light up when comparing them in series ...

The circuit diagram shows a circuit with two lamps connected in parallel. If one lamp breaks, the other lamp will still light. The lights in most houses are connected in parallel.

This play dough sandwich will be the base for a parallel circuit with two LEDs. Decorate your car with wheels made from non-conducting dough (ordinary dough will cause a short circuit between the ...

The basic circuit illuminates up to ten LEDs in sequence, following the rhythm of music or speech picked-up by a small microphone. The expanded version ...
