Car warning lights, with AVR controller

Strobe light controller, using the AVR ATtiny2313 microcontroller. Meant for cars; with front, side and rear warning lights.
AVR car front lights controller

Lights controller for high beams and fog lights on my Subaru. Uses an AVR ATtiny2313 microcontroller.
Emergency LED strobe, AVR controlled

33 high intensity LEDs are controlled with a AVR ATtiny2313 microcontroller. Four flashing patterns that can be set manually or cycle through. Uses an AVR ATtiny2313 microcontroller.
Home power consumption measuring unit, with AVR

Measures the power consumption by counting LED pulses from the home fuse box. Measurements can be read via a serial interface, uses the AVR ATtiny2313 microcontroller.
AVR mood light, 500mA per channel

Turn any RGB LED into a mood light with this controller. Uses an AVR ATmega8 microcontroller.
Light sensor with LED display, AVR controlled

Measures light intensity and shows the value on a LED display, if value passes over/under the set point the output is enabled. Uses the AVR ATmega8 microcontroller.
AVR production line stop alarm

Simple alarm circuit to monitor up to eight inputs, from e.g. production equipment. If any inputs are triggered an alarm is sounded. Uses the AVR AT90S2313 microcontroller.
