There is a problem with timers and the IRremoe Lib. I cant use mills() and pwm. Is there any workourand or some ides to solve the problem?
There is a problem with timers and the IRremoe Lib.
What do you think the problem is? In reality, it is probably your code, which you didn't post.

That all depends on what you think the problem is.
If you read the documentation for the IRremote library you will learn which two pins can't be used for PWM when the IRremote library is in use.
I made an NEC IR library based interrupts, pin 2 or 3 on the UNO.

Either the Remote control blocks r the pwm doesn´t work depending on the used pwm pin..
I use an nano, that means 3 timers. Timerfunctions don´t work too...
int motor_v_1 = 5; /* valucity to pwm */
int motor_v_2 = 5; /* valucity to pwm */
You don't really expect independent control of motor speeds when you are using only one pin to control both speeds, do you?

No I don´t thats why I didn´t
