I am working on a project and got stuck on a point, and I hope somebody will guide me. I have a hardware device which has different color LEDs (green, red and yellow) and I have to calculate how many times each color LED glows for each mode of operation.
The LEDs that are connected to the device are pretty small and will blink only for a couple of seconds, ao I am looking for a very sensitive light sensor.
So what kind of light sensor do I have to use with Arduino UNO to achieve this?
Should I go for BH1750 or do you have any other suggestion?
Thanks in advance.
