I enjoyed this instructive video on OPT101 working with Arduino. Thank you for sharing !

[biotechfordummies]

Clear explanation, good editing....very well done !

Hi, I've used the same method as yours and it worked fine. But after some time, it stopped as it was making a negative voltage at the output (1M+Output). The values of this output make sense, except it is negative. Have you happened to see something like this? And do you know how to make the output positive again?

Why are you soldering the 3 pads?
I´ve been trying to use it in arduino to measure wavelength but i´ve not been having a lot of progress.

Bro my moter driver shield is getting heat up when I connected motors in it I have made this circuit by seeing your video plz tell

Hi, thank you a lot, I just have a quesion and I would be grateful if you could answer it, I reviewd the datasheet for the sensor and found out that the 1M OHM is internal and you already connected it by soldering, so what is the need for the external 1M OHM resistor?

So how does the following function in the Arduino code help?
value = map(value, 0, 1024, 300, 1100);
300 - > 1100 is the spectral wavelength of this sensor. Does that mean we can detect specific wavelengths? What are we actually plotting?

I dont think you should solder those 3 pads in the bottom. You are connecting pins 2 & 4, so the M1 resistor output to ground.

Bro can you make prototype to measure optical density with this sensor?

[jeanetteobusa]

Hello is it also applicable on raspberry pi? if yes, How?
