Hello, I'm planning to build a midi laser harp.. I'd not want to use a frame with receivers on the top.. So I found a couple of sensor which I could use.. but I'd like to hear your ideas before starting the build..
a GP2Y0A02YK0F SHARP which is an infrared distance sensor.. It converts the distance and sends you directly the distance expressed in mv (2.8v to 0.4V - 20 cm to 1.5m) The limit is the 1,5 m distance (it could be enough)
a laser.. but I don't know if there is a prebuilt package or I need to build something by myself and measure the phase shifting.. and I don't know how much the reflection is approximate..
sonar like maxbotix Ez0?
Anyone has some experience, with distance measurements? thanks, Paolo
