hey everyone,
im using a 5v buzzer in my circuit. i want to interface this buzzer to a uln2803 relay driver so that it can power my buzzer. but i do not know how to do this. im taking pin 1b of the uln2803 to the p1.2 of the 8051 and am connecting the buzzer to pin 1c of the uln2803.
how am i supposed to make this work? am i supposed to send a low to p1.2 so that the uln2803 will convert it to high or am i just supposed to send high-low pulses to p1.2?
please help, urgently...
thanks
