The phone's flash light uses LED, which is fast switching because it is semi-conductor. therefore it can be used for communication by adding minimal hardware to it (current driver....etc),
Question is:
1- How fast B4A can switch the LED on and off? (the frequency)
Thanks in advance
edit:
talking about the mobile flash light (not the camera flash)
