You will always sense some blinking, since it's PWM. The PWM technology is different from the DAC technology, and if you are like me, you probably can see the neon blinking. :wink:

Any ways. As long that you will be using noise to power up your led, this will be true. Maybe you could use one of those module

give out 1 DAC and take in 4 ADC and they are simple to program. With these you can make a almost perfect sinus signal so it will also give you a very stable signal.
