The aim of this project is to help blind people, or people with Color blindness problem, who has difficulty to differ colors. The system will analyzes the color of a surface and then pronounces its result through speaker.
The project uses TRS17xx as color sensors. The voltage at sensor output will be varies depend on rays which is reflected by specific colors. The analog data will be processed to digital using internal ADC of microcontroller AVR ATmega128. By using an algorithm, MCU will calculate the data to determines the colors and produce a wave which is stored in FLASH memory and pronounce it via speaker. The Color detector project is designed by Anastasios Kanakis.
