This is my schematic so how can I alculated it?What simulator? What components? If its just the Uno, there are many factors.. Pins high / low... Internal modules on / off.. Power mode...
If you just turn it on its about 42mA ( ish) so with a low input voltage of say 6v then power will be 1/4 of a watt. But that isn't even blinking light sketch...
I find this schematic to shift the signal to positive part to let arduino read the signalsThe amplifier doesn't need all those resistors and the 2.5V. As they are unity gain you could use the simple circuit below.

Your circuit includes points maked 2.5V as a centre rail for the amplifiers.[QUOTE="AlbertHall,
Yes, only arduino current.
I don't understand what do you mean about 2.5v
Not unless you let us know what you are using for a power supply and how it is connected to the Arduino and the rest of the circuits, and which model of Arduino you are using.. You also need to state what value resistor you plan on putting in series with the LED that is connected to pin 13, because it would be difficult to estimate the total current with a damaged output pin and a burned out LED.Okay thank you.
Sorry can you tell me in steps how can I calculated the power consumption?
And what functions will be used/turned off, and what percentage of the time it will be sleeping.Not unless you let us know what you are using for a power supply and how it is connected to the Arduino and the rest of the circuits.

I used 5v as power supply.Not unless you let us know what you are using for a power supply and how it is connected to the Arduino and the rest of the circuits, and which model of Arduino you are using.. You also need to state what value resistor you plan on putting in series with the LED that is connected to pin 13, because it would be difficult to estimate the total current with a damaged output pin and a burned out LED.

I can't know how can I know these data?And what functions will be used/turned off, and what percentage of the time it will be sleeping.
I want general power consumption not accurate.How accurate do you want your answer?
50mA @ 5V is 250mW.
