Okay yes I see how you did it now :)
I did something similar to this. I connected the power pin of the transmitter directly to my 5V source, instead of having this power go through the Arduino first. For the receiver I did the same. I even bought special 433 MHz rated little antennas. The path between the transmitter and receiver is through the air without any obstacles. Still, the range isn't even 4 meters. I was thinking of using a step up voltage regulator of 12V to power the transmitter. But the modules are rated for 20 to 100 meters of range depending of the voltage input (3 to 12V I believe). At 5V I'd say I'd at least get 20 meters, but since I only get at most 3 meters I don't think stepping up to 12V would make a significant difference. Any tips on this?
Cool, thank you :) I see you uploaded the video today, I hope you didn't go through all the trouble of making a video just to answer my question ;) What's the range on that actually? I'm currently considering an HC-12 setup:http://www.instructables.com/id/Long-Range-18km-Arduino-to-Arduino-Wireless-Commun/
Laser Printed PCB's, Perfect and Easy.
I've been struggling for a long time now, but I'm getting really weird results. It seems like it's scanning two items, there are two "rings" of point clouds, one too big and one too small. The real object is just a tube. I'm using a Trust Webcam Pro because the cam you mentioned wasn't available anymore. Is there something not right in my settings? Could you guide me on this?
