WebAug 10, 2016 · R2 we don't know. Using the ADC of the Arduino we measure a value of 681. First we convert that into a voltage: Vout = 681 / 1024.0 * 5.0 = 3.325V. So we know that R2 has 3.325V dropped across it, and since all the voltages must add up to 5V we know that R1 has (5 - 3.325) 1.675V dropped across it. WebSet the selector dial to Ω. Connect the test lead and probes to the component terminals as shown (Figure 4). Observe the readout window to obtain the Ω reading. Compare the results to the manufacturer’s Ω specifications. If the readings match the component, then resistance is not a problem.
