It is possible to do brightness from code without any parts.In from an interrupt ( possibly feedback of a PWM signal ),turn D10 from pinMode() input to output with the staticvalue of 0 as an output.This way you never drive the pin high ( the condition thatover currents ). You still get brightness control.Dwight
I am sure at some point a software fix will come back to hunt me,
hmmm.... i'm not sure but i just had my 16x2 lcd keypad. and i use:analogWrite(10,0); //to turn OFF the backlightand even dim the backlight with:analogWrite(10,50); // 0=OFF; 255=MAX power.
no.maybe they already fixed it. I just had the 16x2 lcd with keypad recently. lucky me
my 1602 lcd keypad shield have "D1 ROBOT" markings.
when you say "visually inspecting" it, does it translate to my shield and/or uno board getting fried?
i let it run for more than 30 minutes already using analogWrite and it appears okay to me.
i'm into software and noob in arduino
