arduino Can''t get consistent readings from Sharp IR range …

+

11/01/2011· The trouble is that the voltage readings back from the Sharp IR sensor aren''t consistent. If I write an app that simple sends the value it reads from the sensor through the serial port and display it on my laptop, sitting the sensor pointing at an object, the values bounce around. Watching the values, I can see that it tends to report one value more than the rest, so I wrote a SharpReader class that takes 20 …
