Most multimeters make voltage measurements starting from one volt and some start from 200 millivolts. With such devices lower-value measurement becomes difficult, especially for DIY projects. Here is a circuit that can measure low voltages, starting one millivolt onwards, with better resolution. Circuit and working Circuit diagram of the millivolt meter is shown in Fig. […]
