The led driver im thinking of using has the use of A low frequency PWM signal can be used to dim the LEDs
So can the PWM outputs of the Ardunio be connected straight to the PWM pin on the led driver without the use of transistors and resistors?
Do all the grounds of both power supplys and the Ardunio need to be connected together?
I know i will need a 10 to 12v power supply for the Ardunio as well. Do all the grounds of both power supplys and the Ardunio need to be connected together?
