WebThe formula to calculate resistance in a circuit is: R=V/I or, more relevant to what we're doing: (Source Volts - LED Volts) / (Current / 1000) = Resistance* So if we have a 12v battery powering a 3.5V 25mA LED our formula becomes: (12 - 3.5) / (25 / 1000) = 340ohms. But wait! (you might say) When I use one of the other calculators I get 390 ohms! WebFeb 7, 2024 · So how do we get a light dimmer using a potentiometer and microcontroller?
