Microcontroller Based Colour Identification System
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 1
Abstract
A microcontroller based system using P89V51RD2 microcontroller for colour identification system is designed and developed. It is based on the principle that the analog voltages of the sensor converted to RGB colours. The sensor OPT 301 is an opto-electronic integrated circuit containing a photodiode and transimpedance amplifier on a single dielectrically isolated chip. This sensor provides an analog input depending upon the colour sensed by it. This analog voltage may then convert into digital form using ADC (analog to digital converter) interfaced with the microcontroller. Digital output varies depending upon the variation in the colours sensed. The P89V51RD2 is a low-power, high-performance CMOS 8-bit microcontroller used in the present study. Further, an LCD module is interfaced with the microcontroller in 4- bit mode, which reduces the hardware complexity. Software is developed in C using Keil’s C-cross compiler. The data stored in the microcontroller along with the name of the colour. The paper deals with the hardware and software details.
