pls help me
i wanted to build something with 433mhz but the thing is i know nothing im pretty new and i got an error when i try to upload my code to the adruino i will show some pictures

thats the code of the receiver
You cannot have both the servo library and the RH_ASK library use the same timer interrupt
Line 1 has no effect at all
The addition of
must be done in the
RH_ASK.cpp
file of the library, not the sketch
https://github.com/dragino/RadioHead/blob/43720d1ed6fbf6719968f5f8cfad21a561b9bbe2/RH_ASK.h#L231-L235
I.e., that library should be in C:\Users\<user>\Documents\Arduino\libraries\RadioHead\RH_ASK.cpp
433Mhz is pretty fast. You’re 18% of the way there to a standard microwave oven at 2400Mhz. I’m not sure the capabilities of the audrino with small signal voltages at that level.

The clock speed of the microcontroller is 16-20Mhz I think. I am a layman for computer engineering but the signal speed you are sending is higher than the microcontrollers clock speed?
By several orders of magnitude
That is Semantics.
