Increased Range for DVM
Voltmeter modules are readily available, both as LCD- and LED-versions. A disadvantage of these modules is the standard measuring range of 200 mV DC. So, with such a module you can only measure DC voltages up to 0.2 volts. Fortunately it is not difficult to increase the measuring range to higher voltages. In addition, it is also possible to measure current with these modules.
