Denoising Sharp Infrared Sensor

Today I have tried to stabilize the output from the Sharp Infrared sensor. The following links are useful. I just put 0.1 uF and 100 uF to the Vdd. The result is significant.


Arduino and sharp infrared proximity sensor + two capacitor for data stabilization


I checked the interval of Serial-USB messages, coming from Arduino with timer object. it is surprisingly VERY unstable.

timer outputs sometimes 0. It means no interval between previous and current values. the numbers are sometime buffered but sometimes not arrived properly on time? I set the baudrate pretty high but 38400 is adequate for arduino. I guess.

And finally the LCD worked…  but I was not able to locate the problem.

Good bye world!
