i have a problem regarding this **broken link removed** sensor circuit.. i have conducted one circuit for testing which is circuit for sensor 1..
however, it can't detect the black line..and also if i try to play with potentiometer the output (LED) will on and off..how make the IR detect the...
In this **broken link removed** site said he is use LM324 as comparator..so is that circuit gonna work? now i want to try construct that circuit.. how i'm gonna to check the circuit is correct or not?
oh..i see..so i'll cover ir sensor with black plastic..thanks for ur explanation..
ur circuit is quite similar with this one **broken link removed** what r u use for comparator? do u use LM324? actually what is purpose of using LM324 in this circuit?
is there any circuit that we can use to reduce the noise? ir is so sensitive to the environment is it enough by covering with black plastic tube?
anyway, i'll try it ..thanks for ur suggestion.
hello,
i'm new here and really need help from u guys..
currently, i'm doing a project which is line following and obstacle avoidance..
can u assist me how to do it?
equipment:
IR emitter n receiver - for line following and obstacle
PIC 18f4520 microcontroller
motor driver L293D
DC motor...
