#127125 - For fun, LED strobe |
The 'for fun' thread got me thinking that I might make an LED based stroboscope. Getting an 8052 to output a variable pulse rate would be pretty straightforward, but does anyone here have any experience of driving LEDs at low duty cycle. I'd like to use a dozen white LEDs and to have a strobe range from 5 Hz to 500Hz, with an on time of 10 microseconds or so. |
