• Hi Guys,Would it be possible to be measure voltage and current with my arduino using the analog input pins? I'd like to measure a voltage between 0-53.4V, and a current between 0 and 20mA (that is battery spesification). With load BLDCmotor 48V/800watt.Need advice, please..

Current = (0.00489*Analog_read - 2.5) M 0.185Which one (Analo_read) value??

dear all,where the formula below come from?// convert to milli amps outputValue = (((long)sensorValue * 5000 / 1024) - 500 ) * 1000 / 133; amps = (float) outputValue / 1000;some one can explain to me about those formula and the meaning of value 5000, 500, 133 ???
