Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...
• If my system is specified to operate from –55° to 125°C, how much will my output voltage vary from the ideal? • My output voltage will be within ±0.1% of ideal if I use ±0.1% resistors, right?
