Hello.
I have been playing around with stroboscopic effect and though I would make myself a big strobe light.
I ordered a few bits and thought this would work:
This turns on the led panel fine if I pull the signal wirre high to 12Vdc, and turns off if I disconnect the wire.
I then hooked up a cheap arduino nano and an adafruit clone 16ch pwm board running at 1.7khz which slowly sweeps duty cycle from 0-100%.
problem is my lamp lit up for a second, then the pwm board let out some smoke.
Nano is no longer detected by windows, and pwm board does not work.
I have spares hooked up and ready for round 2 but I'm not really sure what went wrong.
I should say I'm not great at electronics so probably something simple that I don't understand.
Any Ideas let me know.
Thanks.
12.6vdc supply powers led driver circuit above and also goes to arduino nano vin and gnd pins.
Single wire from PWM signal was connected to my mosfet driver trigger. Wire length was about 20cm I suppose if that is relevant.
