This is just one of the solutions for you to be successful. The RC time constant is simply the product of the series resistance and the capacitance of the capacitor – R * C. With this knowledge, I may be able to time how long it took for the capacitor to reach 63.2% charge, or, since they are proportional, 63.2% of the arduino’s voltage level. Figure 1 Simple capacitance measurement using IC-555. Each Arduino capacitance meter relies on a property of resistor capacitor (RC) circuits- the time constant. 555 Based Capacitance Meter Circuit Diagram Posted by Margaret Byrd Posted on July 14, 2018 2 simple capacitance meter circuits measurement circuit electrical4u from the q and a nuts volts magazine digital block capacitor esr diagram with 555 under meters arduino diagrams S1 is employed as a range switch, and operates in collaboration with S4 (s1/x10) and S3 (x l) or S2 (x3).
