how to communicate 2 arduino unos (with cable connected to PWM)
i try connect directly (1st male to 11 2st to other unos 5 pin) but it didnt work so, whats the way (also i need PWM pins because i have 13 diffrent informations (i use A0 and A1 as extra))

2

What protocol are you going to use for such communication?

3

i search and i think im gonna use I2C

It sounds like you have 13 pins on one Arduino connected to 13 pins on a second Arduino. If so then it is OK to just use A0 and A1 as digital pins just like any other digital pin

NOTE : A0 and A1 are analogue in pins not PWM output pins

What does pvm have to do with this?
For i2c, pins a4 a5 are used on the Uno

6

i use 11 as communication.

7

Can you explain it in more detail? What is "11"? the pin number?
Why do you going to use i2c in this pin?

8

11 isnt gonna be the I2C pin its the pin i try directly connection between two (also i need to send an 0 - 255 8 bit integer)

9

Microcontrollers don't connects like that.
But of course you can try your way.
Good luck

To avoid further confusion can you please post a diagram showing exactly how the 2 Arduinos are connected

im using Serial connection its done
