While (bit_is_set(ADCSRA,ADSC)) // measuring set the reference to Vcc and the measurement to the internal 1.1V reference Here is the Circuit Diagram of my project: Like 3.70 volt for the multimeter and 3.72 for analog pin but when I turn On the gatepin of the MOSFET then Arduino value is like 3.07V and Multimeter value is 3.48V. Meaning if I connectĪ battery with an analog pin and a multimeter at the same time and the value is pretty much same. When I read voltages of individual batteries by corresponding analog pins without turning On 'MOSFET-Gate pins' then Arduino measures the voltages correctly but when I turn on the gate pins then Arduino measures voltage incorrectly. An 8.4V battery powers the Arduino (do not consider the buck converter in the picture). I want to make a 10 channels Arduino mega-based battery capacity tester using 4.7 ohms 10w resistors controlling them with IRFZ44n MOSFETs with respected digital pins.
