The transistor Q2~Q3 control the LED1~LED5 as the rise strip display of the input voltage. If you adjust the R2, the voltage minimum change range is 0.1~0.5V, the increment of the five LEDs is 0.1V; the voltage maximum change range is 1~10V, the increment is 1V. The input resistance of the circuit is more than 100KΩ.
