Help on I2C question

clem57

Looking for a method/device to address as I2C to turn on/off 12+ volts. It needs to be very small and can have an address set. I will have around 50 different addresses to control 3 lights.

 

Thanks

Clem

    How about one of the ATTiny range with a mosfet or transistor to drive the LED?

     

    Alternatively one of the bigger Atmel microcontrollers with something like an darlington buffer chip such as the ULM2003. That way each microcontroller could handle 7 outputs.

     

    @Shabaz has a point about loading the bus with 50 devices, you might need to do some current calculations to ensure the driver can handle that?
