Sensor Led
Sensors, CMOS sensor/LED from mouse and Arduino..?
Hi,
I was wondering if its possible for me to take a mouse with CMOs sensor and LED and connect it to my arduino to check for surface change…I am not exactly sure if its the CMOS sensor that I want or what it is but playing around with my mouse I figured out that in my mouse there are 2 LEDs. One thats always on, another that turns on if there is a movement in the mouse’s surface WITH the 1st LED reflectign the light….
ALL I WANT is that reaction it produces, that 2nd LED lighting up when change in the surface occurs. What can I do to accomplish this?
Older mechanical mice used an encoder wheel with an LED / phototransistor.
Newer optical mice use an LED / photosensor that has much greater sensitivity.
They are usually tightly coupled (spaced near to one another) and if you are looking
to use it with your arduino then you need the datasheet on the part.
Some are marked and most are not ! So determining the gain (sensitivity) is hit and miss with software.
LEDs as sensors!
