433 mhz tranciever - Serial Communication problem

Hello everyone;

I'm trying to read some analog value with arduino uno , send it via RF transmitter to another arduino that has RF reciever. There is no problem up to here. After that, I send these datas from arduino that has reciever to another arduino mega via Serial communication. Again there is no problem. I recieve the data on arduino mega and convert it to integer. I use this intiger value to drive servo. But here when I connect the servo ( 13kg/cm but there is no load on it) the serial communication between mega and reciever arduino becomes disconnected. Interesting information is this, when I recieve this datas from the arduino that has transmitter via serial communicaton I easly drive servo depend on my values( gamepad's pot value ).

So I want to know why this problem happens when I recieve datas from arduino that has reciever via serial communication.

Thank you all for your helps :drooling_face: :slightly_frowning_face:

It obviously involves your code. You didn't post it.
