I don't understand how your 2 resistors are going to amplify...
You don't need to, because I was explaining how to get a lower voltage from the supply.
The supply is 2V to 3V not 10V.
Then the resistors need to be adjusted accordingly.
Just use: R1 / (R1 + R2) * supply
and the result is the voltage to use.
R1 is the resistor connected to ground, and R2 is connected to VCC or +ve.
For a 3V supply, use 1K for R1 and 2K for R2
For a 2V supply, use 1K for both R1 and R2
Increase both resistances by the same number (pick the number) until the current provided doesn't blow up the rest of your circuit.
and PLEASE do NOT use ONE OHM for R1 and ONE or TWO OHMS for R2.
because then you will be delivering AT LEAST 1 1/2 AMPS from the measly 3V supply (because I=V/R). worse yet, if you are running 3V off a battery, that battery will most likely die in the next 5 to 10 minutes (or even less).
