Hi,

“control the voltage using remote control”?? what that means ? more details please

[Muhamad alif]

for example when i press 1st button output at arduino is 5v

and 2nd button output from the arduino is 9v 

[Ashutosh Bhatt]

micro controller can give only two outputs high (5 V) and low (0 V)

the only way to get variable output is to use DAC.

but i wonder where your RF module comes in picture?
