Hi all, i am using freedunio uno , with this borad i want to reset my andriod chip . please give your valueble suggestions how to implement this

Please give more details of the requirement.

in my last project i used relay to on and off the Andriod board . that relay operated by atmega 8 controller by sending sms to the sim900 which is interfaced with the controller board . now i want to remove the sim900 then how can i operate that Andriod board , i mean ON and OFF

so i want to use the Freeduino board and , my andriod board has a processor it self .

You keep saying android board. Do you mean Arduino?
