This circuit yearn for act the performance of the equipment,otherwise Check the fuse here the circuit.The circuit is diminutive and the power supply voltage of all kinds. It demonstrate with LED, 2-color in individual. Which is cathode universal kind,the anode has two separate terminals. If the circuit is functioning well LED, it revealed in wet behind the ears colour.The display is red, as the fuse into the circuit is damaged.The resistor R1 limits the current to gush through the LED is roughly 2 mA.This is an adequate amount to produce the LED light.If it lowers the R1 down, the LED light up.
|Alarm LED Light Circuit Diagram|
In the conventional setup of the circuit and The fuse is not damaged. The zener diode to prevent the green and red LED illumination up in chorus.Zener diode prevents the LED is simple and red illumination all together.
The piercing efficiency LED, as soon as connected trendy like. The red LED uses high-pressure, so with the intention of single green LED illumination up only. Diodes D3 and D4 wish prevent dodgy instead of the LED. While the semi cycle downbeat voltage of the alternating current voltage.However, if the DC supply voltage.I act not retain to manage diode protection.
