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.
Electronic switch for LED lights, 4 channels, 9 to 24 volts in, 5 volts out. Uses an AVR ATtiny2313 microcontroller.
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.
