yes u r rite but if we modulate the light with high frequency them i think our problem is solved...audioguru said:Since the transmitter modulates the light from the laser then its range will be small during the daytime and its receiver's sensistivity pot will need to be turned down to avoid light causing the phototransistor to saturate.
The receiver is an AM detector so it will create loud buzzing at night from street lamps.
It will be extremely difficult to aim the tiny laser beam onto the tiny phototransistor at a distance.
n abt the rx. if we make the rx. as a photodetector...thn thr must not be any problem.....wht u
