I'm working on a interface to controll a special LED stripe via PWM.
Special cause they're 2700 K and 6400 K on the stripe, one with a reserved polarity.
You can controll the lightcolor via the frequenz that you use to switch between the polarity.
For the tested a classic motor driver circuit with an L293 H-Bridge.
It works out fine, but the working range of the L293 so to small (just up to 600 mA...)
So i'm looking for another H bridge or maybe a better way to controll the LED Stripe.
At the end I would like to use DMXControl to controll the stripe, so will need the right
DMX Driver, too.
Hope you can help me out, thx
