I have to sense a voltage range of 0-25V dc and send to the ATMEGA 32 microcontroller. I want to use a voltage divider for sensing the voltage. But the problem is isolation is required between the ...
I am allowing the current through a DC motor to flow through a small resistor and measuring the voltage across it. I need to give this analog Voltage to an ADC of micro-controller to do some signal ...
I'm trying to design a circuit to measure power of 230VAC (MAINS), with the ADC of a small MCU. I have designed the part of the circuit to measure current, but my solution to measure voltage is ...
