Hello, This is a pretty standard question, but I would love to know how others work out the resistance calculations for different sensors/controls/etc from data sheets. I've found data sheets vary quite a lot, providing different types of data - eg. watts + ohms or volts + current. Example below sh…

Working out correct calculations for resistance from different data sheets

Nether calculation is correct, speaker is AC device, but arduino outputs DC only. Use power amplifier, or USB speakers.
