Signal Indicator Circuit
Working Explanation
The working operation of this Bike/car turning indicator is simple. The above circuit schematics are shown in the circuit connections. In this Bike Turning Signal Indicator circuit, we have used one 10K and 1K resistors and a capacitor for creating a delay. However, the 1N4148 diode is associated with reverse bias at the 555 timer IC yield pin to maintain a stable current. Because of the base current of the BC547/MPS42A (NPN) Transistor drive, the LEDs will turn ON and OFF. LEDs are associated with the semiconductor through a 220ohm resistor concerning Vcc. This 220ohm resistor will spare LED to may get harmed.
Applications and Uses
- Uses as a bike or car turning indicators
- It likewise utilizes knight rider LED circuits.
