hello!!!
my university had given me task to detect 3 colours green , red and yellow through microcontrollers in line tracking robot….. m confused either to use adc or direct comparators output to microcontrollers for colour detection???
are you using LDR and colour LED for the colour dectection….
in that case ADC will be more suitable….
plz specify what you using for colour detection so that i can help you out…
m using phototransistors and led …. i have to detect colours of three boxes placd randomly and then after sensing the colour ,there will be 3 pads placed on the floor…and i have to pass my robot through the pad of corresponding colour e.g, if i had sensed red box..then my robot should pass throug red pad…and then so on…
m using phototransistors , leds green red and yellow… and then lm 339 comparator…after that m cnfused ??? plz tell me as early as possible!!! and explain also…
