Abstract: Digitally Addressable Lighting Interface (D.A.L.I.) is a technical standard for network-based systems that control lighting in buildings. The aim of this project is to design and implement DALI in a real time environment. In this project, the work is carried out using a system consisting of a PSoC microcontroller and a PIC microcontroller. The PSoC controller performs the main function, receiving & processing the input and sending the data to the PIC controller. The PIC microcontroller performs the function of controlling the brightness of the bulb. A Zero Crossing Detector (ZCD), used to read the frequency of the microcontroller and trigger the circuit, is connected to the PIC microcontroller for operation of the system. The bulb i.e. the load, which is an A.C load and the controllers, which operate on a D.C supply are separated from one another using an isolation circuit. The input from the user to control the brightness levels is done using a 4-wire resistive type touch screen as the digital communication device. This entire system is incorporated twice for the control of two different loads, or incandescent lamps.
