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

    Hi Clem!

     

    Is this related to the Xmas lights challenge? Could you sketch roughly what you wanted to do with the I2C control and LEDs, I wasn't sure what the I2C control was for (i.e. is it to switch different banks of LEDs into the Arduino shield)?

    Also, I2C isn't good for long distances often (but maybe your requirement is for short distance) and a serial chain of 50 would have an impact too (there are workarounds, e.g. additional repeater type chips, or use additional I2C bus,etc).
