Record and play back a few seconds of input stored in EEPROM.
Nice project ! How do you adjust the distance between 2 distance sensors, is it multiple of Ultrasonic Wavelength (physics question) ? Or Trial and Error to find the sweet spot ?
I was thinking the same thing ! Laser
Ok ! I am doing tests too ! no problemo
