LED with 5V Power
I have built a complex circuit using Arduino Uno, Breadboard, LED, 220Ω Resistor, Jumper Wires, USB Cable and it was nothing new for me but one thing which was that my Arduino was not working so i changed the connections and jumper wire 3 times then I got to know that it is not working.When the led worked without any defect continuosly without blinking therefore I got to know my project is working properly.
