Axiometa Ohm's Law - Soldering Kit

Eight LEDs are each paired with a different resistor value and an independent toggle switch. All LEDs share the same supply voltage, so the only variable between them is the resistance. Toggling each switch shows the direct effect of resistance on current and brightness across a range from 150Ω to 22K. The relationship between Ohm's law and perceived brightness becomes immediately visible without needing a multimeter or calculation. The resistor values are printed on the silkscreen for quick reference during circuit design.
