Hi All,
I'm new to this forum. I'm doing a project and have a car reversing Ultrasonic sensor that uses a 4052. I want to tap the output of the 4052 to my Uno to selectively read each of the 4 ultrasonic sensors to know which particular sensor has detected an object. Can anyone help please?
Are you saying the 4052 is in an existing circuit?
OK, you provide the circuit and we will look at it.
Yes, the 4052 is on an existing circuit (a Chinese reverse parking unit). It is connected to what I think is a microprocessor (the reference number has been erased from it). I was able to establish that pin 9 (S1) of the 4052 is connected to pin 8 of the microproc and pin 10 (S2) of the 4052 connected to pin 9 of the microproc.
4052 Other IC (Microprocessor?)
Pin 9 (S1) Pin 8
Pin 10 (S2) Pin 9
Pins (11 & 4), (12 & 1), (14 & 5) and (15 & 2) to ultrasonic transformer circuit.
