Hi everybody,
I finally got my sparki one week ago.
I am experiencing problems with the ultrasonic sensor;
Wall avoidance example code sometimes works for a while, but sparki begins to always go backward;
So I am testing the distance measured by the ultrasonic sensor, filtering the results doing the average, as explained in one lesson: it is very often stuck on 5 cm or less!!!
I took the sensor out of its place, and for some moments it seems to work while it is in my hands, giving possible distances; but when I put it in place again it begins to give distance of 5 cm for long time or less than 5.
In the end it seems to give umpredictable results;
Do you think the sensor is broken? How can I check it?
Thanks for your help
