i am required to design a range sensor by using opamps, any kind of capacitors,resistors,LEDs . Timers are not allowed to be used. Also only DC voltage sorce allowed it should not be more than 3 DC sorce. th basic requirement are that:
design a circuit that measures 0-60cm diistance and by the help of 4 LEDs visualize it.
0-20cm 1 LED is on. 20-40 2 LEDs an so on.
TSOP1138(TK 19) allowed to use of course
