i just buy the ultrasonic sensor(SN-US-40) from Cytron, and i need connect the sensor with the Arduino, and i dont know the circuit for connecting the sensor, can anybody guide me???

What is the output of this ultrasonic sensor? Sorry no time to browse through Cytron page for that sensor. Normally is analog output right? Just setup the Arduino to read analog voltage. Arduino is very famous microcontroller platform that comes with plenty of sample codes and projects. You should be able to get one :geek:

SN-US-40 is purely the ultrasonic transmitter and receiver. It is not a complete ready to use ultrasonic sensor. Not really sure is there any sample circuit and code for Arduino, you can try to search it. I have seen people using the maxbotix EZ1 on Arduino, quite easy for that.

Here is a sample circuit from internet search that might inspire you if you still want to consider the transmitter and receiver.

You will still need to develop program for it, or try to search for its sample code.
