Hi,
I am using a couple of L298 H bridges controlled with an Arduino to control led Christmas lights which are wired with leds at alternate polarity.
One I have connected to a 12vdc regulated supply and that works fine.
The other I have connected to a 24vdc regulated supply but when connected to the L298 the voltage shows up as 35v - what is going on here ???
The power indicator led does not light up and the outputs don't work using the same inputs that work ok on the 12v bridge.
I know the second bridge is ok because if I connect it to the 12v supply it works fine.
I have removed the 12v jumper on the second bridge.
Any help much appreciated.
Mike
