  • I was a bit misled by the description “The sensor provides very accurate readings of 0 to 255 inches (0 to 6.45m) in 1 inch increments with little or no dead zone!”. In the data sheet it says “Objects from 0-inches to 6-inches range as 6-inches” and this is in fact the case. I don’t consider this to be giving an “accurate reading” when an object at 0.5 inches reads as 6 inches. If you need a sensor that will allow you to accurately stop very close to an object, this is not that sensor. I (now) understand this is a common limitation of ultrasonic sensors, and I can’t blame Sparkfun for the speed of sound, but this should really be worded better.

  • Google “Amarino” for Android Bluetooth to Arduino. It is more oriented towards using the Android phone as a sensor package and doing the control code on the Arduino, but the communications library can be used from the Android SDK too.

No public wish lists :(
