hi guyz…my elder brother is working in an automobile company. One of the cars has to be manufactured in two different colours. the two colours are ‘black’ and ‘arizona blue’.In diminished light both of these colours appear to be one and the same and eventually leads to manual error while assembling the part on to the main body of the car….can anybody please help me know/build a circuit which detects ‘black’ colour OR help me with a circuit which can discriminate two different colours which appear to be the same in diffused light?????? this would mean a lot to me…..thanx……..
for doing this you can use a IR receiver and transmitter pair and interface it with an ADC. IR will give different output for different colours and hence ADC will generate different output. You will need to calibrate the ADC for blue and black colour. The output can be displayed on LCD or any other output device.
For higher resolution you can adjust the V0/2 voltage.
