While performing gesture test i am getting 0 on serial monitor .there are nothing comments like apds initialiazation complete.only zeros are printed Plz.tell.me.what is the problem.
Hello there! I have a few questions: 1) I want to use this inside a lightbox, that will be 3in deep. Do you think it may work??? Will the light inside the box interfere with the reading? 2) the LEDs I want to use are 12V, how can I adapt the voltaje to make it work with my Arduino Uno? Thank you again!!
Hi! 1) I haven't tried it but I believe id will depend on the color of light inside the lightbox. The results should be best with cool white lighting. It will also depend on how much light seeps INTO the lightbox from the outside. Ambient lighting (i.e. all the light sources except the white LED illuminating the surface to be read by sensor) will contribute to error in measurement and that's why I added a black box for my sensor. 2) You don't have to adapt the voltage if you power them from external 12V source. If you'd like to power those from Arduino then it's a different matter altogether. For USB-powered Arduino you'd have to add a boost converter, or if it's powered from 12V power source you can just connect the LEDs there as well.
Thank you for your answer! 1) The LED light color is Cool White. So in this case, I would need to create some sort of box for it to block light and maybe plug that into a some sort of straw... so it can read through it?... 2) the APDS-9960 feeds with 3.3V I think, right? that was my question. Because right now, I am trying it also with a RCWL-0516 and they don't work unless I fix the voltage. I was curious if I needed to do the same to make this one works. Thanks!! :D
As for the lighting, I'd say trial and error works best for these sensors. Try measuring colors in your lightbox with bare APDS-9960, then try shielding it from what you think may emit wavelenghts different from plain white (frontal panel of the lightbox maybe?). Then compare the results and decide which works best. If you decide to write about your efforts and end result, do send a link - I'm curious. Regarding voltages - I don't know about your setup but yes, APDS is powered with 3.3V power source. Check out my post (link in the description) - I overcame this by using modified Arduino Uno that works on 3.3V voltage levels. You can do the same (12v-> 12VLED and 3.3VArduino->APDS9960) or come up with some other arrangement.
The sketches I'm using in this video are just stock examples from apds9960 library here: github.com/sparkfun/SparkFun_APDS-9960_Sensor_Arduino_Library/tree/V_1.4.2 You can also take a look at the full description of what I did and the results if you read my blog post, the link is in the description of this vid. Cheers, Vadim.

Plz.tell.me.what is the problem.
Is it good for light intensity measurement...what is the range of light measurement in this sensor ??
Is it possible to add more functionality to gesture detection I mean like now its 6 and what if I want to detect 10 different moves ?
Does APDS-9960 has a power saving mode?
Very nice video. Thank you!
does it have to be at surface ?? can i put this backside of a thick plastic
Can't test it right now, but it should be alright provided the plastic is transparent to IR light.

congratulations! What's sketch for rgb sensor APDS?

Great!
Stop giving me the finger ! :P
