The simulated LED Bargraph module is a new voltage indicator module from Alsrobot. The analog LED Bargraph module contains 6 LED onboard, the number of LED lights can be determined according to the size of the input voltage value at the S terminal, input voltage is between 0 and 5V. The less the voltage, the fewer lights and vice versa. The analog LED Bargraph module contains a signal matching adjustable resistor, you can adjust the input voltage limit from 2V to 5V. When the input voltage is 0V, there is no LED lights up. The number of LED lighting increases gradually with increasing signal input voltage, 6 LEDs are all lit up when reach to limited input voltage. The interface is equipped with 3P anti-plug interface, easy and safe to operate and install for the green hands. Specially afford 4 M3 fixed installation holes for direction adjustment and easy fixation. It is compatible with Arduino.
