Abstract (en)
Two-way to multi-way light emitting diodes (LED) control circuits and methods are provided for controlling LEDs. A two-way circuit comprises an integrated circuit having a first input-output (I/O) pin and a second I/O pin, two lines, two LEDs namely, a first LED and a second LED. A three-way circuit comprises an integrated circuit having three I/O pins (i.e. a first I/O pin, a second I/O pin, a third I/O pin), three lines and six LEDs. A three-way circuit comprises an integrated circuit having four I/O pins (i.e. a first I/O pin, a second I/O pin, a third I/O pin, a fourth I/O pin), four lines and twelve LEDs.
