Warning strobe light controller complete with LEDs
Warning strobe light controller, connected to four warning lights with 10mm high intensive LEDs.

The warning lights controller has two PWM driven outputs, that each can handle a load of 3 amps. It has five sequences, and can be set on a single sequence or to cycle through. When selecting a sequence manually it is stored in EEPROM and continues on power-up. Much of the hardware and software is based on the Emergency strobe light project. Can be used to drive the Warning lights with 10mm LEDs project. Powered by: 9-24V.
