Hi,
I need a simple circuite/ module for ultrasonic TX and RX, I should be able to tune them between 20k to 25k frequency ..
my main goal is to send some pulse(2 bit data) and receive the same , and maximum distance would be 10m . Here I have to go with the frequencies b/w 20k 25k .
At the first stage I want to send some signal at some particular frequency ( say any frequency 22k) and receive the same ..
can any one suggest me about how to start this one ..
Regards
Ravee
