The green way of looking - FritsLDR
August 21, 2008
Hey - rock! I was having a hard time getting my project now named FritLDR fine tuned; I wanted this method to work also in harsh conditions, and it was a quesstion of ever tuning, I did not like that!
BUT THEN...!!! All the time I was turnig the LED(s) ON, and measuring, off, measuring.. THEN I just tried to make it ON/pause 10 mil sec / measure - OFF/pause 10 mil sec / measure and OMG!! NOW we are talking!
See the video of I just had the time to make before family called in.. This is not very powerful Green (the weaker) LED's. AND it is with a much smaller LDR.. AND it is STEADY!
(I am so happy :D)
This may very well also eliminate every problem with 50Hz light disturbing.. We are simply averaging it out by this slow measuring.. but it is still way fast enough for a bot to react!
Cool. I like a robot that flashes (visible) light to find it's way / check things!
More to come, walkthrough etc :)
