transistors - Getting rid of floating input in a logic level converter


Is it possible to make the output of this circuit 0V, when the input is floating as shown in the picture . I tried adding a pulldown resistor to the input, but it only worked at a very low value(100 Ohms.)


circuit


Can anyone provide a better schematic, one that does not sink current to the input and reflects floating input as 0V output? I have extra components available to me

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
