IC 8211 Used to Bright LED

This circuit can use with power supply since 5 volt until 25 Volt. When voltage of power supply or battery agree come to lower location level keeps. It make LED bright show know. Although the circuit this use how many is the equipment not, but there is the stability and accurate in good moderately work. Because of use IC Voltage Detector 8211 that bring build be Voltage Comparator Circuit. Which have Voltage Comparator at certainly stay within the integrated circuit. Using fines to decorate VR1 give Volt tall more Voltage Comparator The a little when level Battery Volt lower LED as a result bright suddenly.
