I don’t understand which voltage reference the PWM signal is taking from.
I saw online that i should connect the 5V from my arduino to pins 1,16 and 9. and on pin 8, i should connect a 5V supply with atleast 3A.
But if i send a pwn signal of saw 200 from the 0-255 pwm pin, seeing that my arduino 5v is really just 4.7V will the PWM signal map on this 4.7V or will it map on the 5.2V i get from the pin 8 ?
