Hello
I need some help to design a transmitter using an RF Transmitter module and my PIC12F635. Problem is I have been given a 12v battery and I need to provide 12v to the module and 5v to PIC - All upon button press as to spend no current while no button is being pressed.
My guidelines are to minimise current consumption as well - I have tried using 7805 but my current consumption (eventhough its momentary) is HUGE 70mA ( my little 12v battery drains in few days upon few clicks every day).
My project makes PIC pins high upon corresponding button press, upon which depending on which pin is made high - corresponding data is sent.
I Hope someone can help! :)
Thanks
