In the kit lighting protocol based on master slave controllers light dimming is based on adjusting the voltage which gets to the lamp. Light dimming has been possible for many decades by using adjustable power resistors and adjustable transformers. Those methods have been used in movie theatres, stages and other public places. The problem of those light controlling methods have been that they are big, expensive, have poor efficiency and they are hard to control from remote location.
In the kit lighting protocol based on master slave controllers we are working on is based on the same protocol i.e. to control the intensity of the light. The project is based on the microcontroller. This is just the demo of how one can control the intensity of light by a microcontroller. We are showing this by using two light bulbs.
In the kit lighting protocol based on master slave controllers the working of this project is quite easy. First we select the bulb and the microcontroller for which we want to control the intensity. Then select the intensity type i.e. LOW, HIGH, and MEDIUM. The signal so generated is decoded by the microcontroller which then controls the bulbs intensity.
