Using an arduino to test load? Nerd jokes are getting out of hand. Answer is resistors+heatsinks. Or lightbulbs if in a tight budget.

- lutusp 13y agoThe problem with light bulbs is that their resistance changes wildly based on applied voltage, so they're not very reliable indicators of power dissipation unless you can measure both voltage and current and multiply them together in real time. A big resistor in a heat sink, yep, that's more like it.
