Simulate LED duty cycle of BLM_Scalar

7 posts in this topic

Is it possible to simulate the LED duty cycle of BLM_Scalar with a Core32 + DOUT module? I want to check the brightness of the LEDs I've got before ordering more.

Thanks :)

Since not only the DOUT, but also a transistor driver is involved, you have to build up a (small) part of the circuit.

Thanks TK.

I've got my BLM_Scalar PCBs now, just wondering - is it OK to use different value resistors for the LED sections? Ie. 220ohm for green, 470ohm for red.

Success!

Tested with a breadboarded LED and the colours cycle as expected.
