Dear team kindly assist me on how i can get my circuit & / code to work to achieve the objective of displaying distance at which the cable is in open circuit after being cut by thieves. for my laboratory prototype i will use a twisted pair stripped from an ethernet cable to detect theft in ranges of 0,5m to 12m
i am using a capacitor to rep open circuited twisted pair cable in the simulation (using the fect that length and capacitance are directly proportional and the esd effect). On proteus the simulation is running fine , with some longer delay in outputing the freq and distance for 100pf or below.
transfering the simulation to the breadboard circuit i have attached is giving me this “inf” error for my frequency value. i am here for your assistance
