Strobe provides regular flashes of light. Usually Strobes are designed using Xenon Tubes, Here is LED based simple solution can be used as strobe for entertainment and events and also as warning signals, Project is based on PIC16F1825 micro-controller with two digit frequency display.CAT4016 IC provided to drive 2 display.
Project provides TTL output signal, frequency 1Hz-25Hz, Tact switches provided to set the frequency. Use solid state relay , BJT transistor or Mosfet at output to drive LED, choose right load driver as per LED required current.
The CAT4016 is a 16 channel constant current driver for LED billboard and other general display applications. LED channel currents are programmed together via an external RSET resistor. Low output voltage operation on the LED channels as low as 0.4 V (for 2 to 100 mA LED current) allows for more power efficient designs.
A high-speed 4-wire serial interface of up to 25 MHz clock frequency controls each individual channel using a shift register and latch configuration. A serial output data pin (SOUT) allows multiple devices to be cascaded and programmed via one serial interface. The device also includes a blanking control pin (BLANK) that can be used to disable all channels independently of the interface.
Thermal shutdown protection is incorporated in the device to disable the LED outputs if the die temperature exceeds a set limit.
