Hi There,
Pretty fundamental and basic question, that I'm failing to find an answer for on google (I'm sure I'm just a dumb dumb).
I play in a band. We want to add on stage lighting to the live shows. My thinking is an Arduino LED based system is a good place to start - However, PWM in lighting systems is the bane of many a touring guitarist, as guitar pickups have a tendency to pick-up the frequencies of the pulse, and a lovely hum finds it's way to your amp (bad times all round).
My questions are:
Does anyone have experience using Arduino's for live stage lighting?
And if so, does the PWM create any issues with hum?
My hope is that with the low voltages needed to power LEDs, inductance is not a issue - but maybe sharing a common ground (earth) with an amplifier might be?
Thanks in advance for any assistance anyone is able to give me,
Hank
