Here I present you a little kit that you assemble yourself of a nice voltmeter it can measure from 0 to 30 volts when using external power and from 3.8 to 30 when using single power supply mode. Take note that if you exceed 30 volts you will damage the regulator and may damage the IC and LED display.
Thanks for watching
