Power affecting transfer speed with 434MHz RF.

Hello all,

My project is Gesture control Robot using accelerometer. I am using Arduino Leonardo, when I connect arduino to the laptop using micro USB (i.e the power to arduino is through micro USB), the output of the accelerometer is fast through 434MHz RF, but when I power the arduino through another given power socket, the output of the accelerometer is delayed by 6 to 8 seconds. What may be the problem? Please help me.

Hi,
Can you post a picture of the socket power supply?
What voltage/current is it?
Where are you connecting it to the arduino?

Tom....
