We liked that he used three different meters to show how it works and the difference between a 2-wire and 4-wire measurement on a small resistor. There’s an even stranger method using 3 wires to ...

Using the 16-bit ADC ... The measured value is shown on the OLED display at the front, and in resistor color-code on an enormous symbolic resistor lit by WS2812 RGB LEDs behind.

Using properties of a series circuit, the sum of the voltages across the LED and resistor R must equal the supply voltage. \({V_s} = {V_{LED}} + {V_R}\) Now substitute the supply voltage (\(6V ...

Our Circuit Design Calculators for Engineers and Students are free-to-use tools that help you quickly determine key parameters ...
