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 ...

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 can drive up to ten strips, formed by up to five ...

Abstract: Light emitting diodes (LEDs) are have many features that make them attractive for use in an increasing number of applications. For many of these applications it is desirable to have LEDs in ...

We all carry supercomputers in our pockets and use dozens of electric gizmos every day but rarely stop to marvel at the magical act of flicking a switch. Use your ordinary conducting and extraordinary ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

If there are no branches then it's a series circuit. If there are branches it's a parallel circuit. In a television series, you get several episodes, one after the other. A series circuit is similar.
