Hey guys I'm having some problems using the function analogWrite. I'm developing a program that get data from a remote control (infrared) to adjust the led brightness. But it seens that the PWM is not working, I tested other programs and they worked very well, so it's not a problem with the board. The just turn's on when I send 255 to the function analogWrite, values between 0-254 does nothing. I will post the code here, so if anyone sees the error, please tell me! Obs: pinoLed = ledpin
