Description
This project functions as a simple strobe for driving a high power type LED. The output driver provides current limiting suitable for use with either 350mA / 1 Watt LEDs or 700mA / 3 Watt LEDs.
Output from these LEDs is extremely bright and visible from a considerable distance, even in daylight.
Four jumpers provide options for changing the pulse width, strobe repeat interval and single or double strobe flash. There is also a Strobe Inhibit input that can be used to stop the strobe pulse using a switch. The programmer ready code has default timings which are easily customised by editing values in the PIC's EEPROM at programming time.
Warning. The light output from Power LEDs is very intense. Avoid looking directly at the LED when operating.
