I think it was a 2N2222, but any NPN should work. Note that I used the transistor to switch ground to the servo, not battery. Also try different values for the base resistor to make sure the transistor switches on fully when the microcontroller pin is high.
Clever! I love it.
A simple way to implement persistent state on the particle platform is to use the EEPROM (byte readable and writeable storage).
double value = 5.0;
const int address = 0;
// at next boot
