Voltage Indicator Zener diode
In electronic instrumentation is needed.One friend of mine, once said that a good tool. Not need to be expensive. It is important to use enough. Today I will try to collect circuits Simple
Voltage Indicator.
This circuit is suitable for an indicator to audio signal lower than 3Vp-p. In the circuit, we use a very small parts with only two of the LED display and built-up resistor for current depression.
Circuit Indicator Zener diode
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 .
