Today we come to see Voltage Level Indicator in model easy most. It is use easy part electronics only. The Zener Diode, Resistor , and , LED as a result can show already. By in each the circuit LED stick bright when V+ go up arrive at Breakdown voltage. And Vz of Zener diode +VLed should use RS for LED one by one. The circuit on the right will testify read the value is Bar Graph. When Zener Diode quietly enhance the value Vz . This circuit may is is simple good may advantage for friends , please sir.
