level shifting - Increasing Voltage



I have a binary signal, 0V to 1.4V, which I can't change directly. What circuitry, (on a PCB) can I use to increase 1.4V to at least 2.5V.


Do I need a transistor? I guess I'm looking for a switch that will "close" when there's 1.4V? I'm a complete noob at electronics, but I'm alright at physics and understanding the equations

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...
