Led Schematic Circuit Diagram. Each electronic component has a symbol. A circuit diagram or a schematic diagram is a technical drawing of how to connect electronic components to get a certain function.
The anode of first led in bicolor led is connected to the anode of second led of 10 th bicolor led and in the same fashion the remaining leds are connected only the second anode of first bicolor led is connected to the reset pin of the cd4017. The configuration is conventional. When we connect the ac supply voltage to the circuit then the starter act like short circuited and current flow through those filament located at the first and second end of the tube light and the filament generate heat and it ionized the gas mercury vapor in the fluorescent tube lamp.
In electronics an led circuit or led driver is an electrical circuit used to power a light emitting diode led.
S1 is provided for turning on and off. In the bi color led it should be connected to the counter as shown in the circuit. Circuit diagram is an open source and free software used to design electronic circuit diagrams. Here the arduino uno schematic diagram click to enlarge.
