Flagpole pattern display circuit
Using transistors Q2~Q6 to control LED1~LED5, the strip shows the rising voltage. To adjust R2, the minimum change range of voltage is 0.1~0.5V, the increment of five LEDS are 0.1V; the maximum change range of voltage is 1~10V, the increment is 1V. The input resistance is more than 100kΩ.
