mBed Tutorial 8.7: I2C Reading Data from the TCS34725

[@alexperukarote6370]

Great tutorial! Regarding the output rate of the readings; I am using an Arduino Uno, and using the example sketch from Github. The readings are being output every second. Is it possible to make it output readings at a faster rate, such as every milli-second? Thanks!

how do you convert those raw values to RGB ones?

Could you please explain a bit further to me how we got to write 146 to the ID register, 129 to the timing register and 143 to the control register, i think i missed something there. thanks in advance

I guess you might have solved this by now, but if you watch the video where he runs through the data sheet, all will become clear. It's to do with the command register. He explains it far better than I could...

Hi, great tutorials I just wondered if you had any advice about attempting to calibrate the sensor to enable a more accurate colour response?

[@bmebuilds2972]

Sophie Kirkham That's a big can of worms. Part of the color response is based on the light that is being emitted by the LED, and the distance the object is from the sensor. Typical cameras can autofocus and autoadjust, which help to remedy this issue. For a simple application, you could just get some colors you want to detect at a set distance and brightness and see what values get picked up, and calibrate accordingly. This will of course, limit your ability to detect other colors outside of the ones you used to calibrate. An advanced application will be able to adjust the brightness of the LED based on the general ambiance, and take into consideration the different sensitivities the sensor has for each RGB value.

hello every body can we use this sensor as a light intensity measurement sensor? thank you!
