Arduino Input Voltage And Current. Equal to 1023 which gives a resolution of 49mV per unit. Once the analog input is given to Arduino the measurement of powerenergy is done by Arduino sketch. For pin description of arduino nano let us assume some basic numbering. The 33V pin is also powered from the FT232R voltage regulator that supports up to 50mA.
The highest reference current consumption has the Arduino Uno with 9843 mA. Also the total current through the supply or ground rails ie. When powered by USB. Or ii Digital where the Arduino switches the heater current on and off quickly eg 100 - 10000 timessec. The Arduino has an ADC built into it attached to the analog input pins. Obviously this is a bit impractical as youll probably want to measure input voltages exceeding that.
Read the analog value double voltage Input 50 10240 10.

Dynamic Data Acquisition Charge the capacitor in the RC circuit shown in Figure 2 by placing a source voltage between nodes 1 and 3 ground. These pins are power pins vin is the input voltage of the board and it is used when an external power source is used from 7v to 12v.
