Negative Voltage @ ADC
Posted: Thu Nov 02, 2023 10:34 am
Hello!
Recently trying to make one voltmeter which should display negative voltage i.e. -17.5V to 0V, tried to search the forum with more or less subject but nothing popped up, after googling got some idea about using op-amp and off set the voltage etc.
Was curious to know if someone has got something to add on this topic, if tried earlier, it will save some time in building the hardware and use same for coding.
Thank you.
