Household leds are led bulbs that are used in houses. Basically bulbs with leds instead of tungsten.i decided to use these led bulbs because it's easy to switch them at a very fast rate.
I plan to use on off keying modulation. For every 1 the bulb shall be on, for every zero it shall be off, this will happen at a very fast rate, that the human eye won't be able to notice.
