| Abstract: | The control system on LED lightness base on DAC0832 and MCU is designed in this composition.DAC0832 transform numeral to simulation and control the lightness of illuminant.The MCU is the core of this design,it control D/A conversion DAC0832 transforming data,it also control multiplex electron switch and the hold voltage circuit to make the lightness change gradually.The system has advantages of little elements,universal circuit.It can be extend to more complicated system for controlling neon light. |
