I'm a programmer, but a complete beginner in electronics. I've been following this guide where one of the first projects is to create a LED circuit using this circuit diagram. I've tried wiring up the simple LED circuit, but it doesn't work.
I'm guessing some of these parts have a significant change of failing due to poor production, so I swapped out the LED's, jumper wires, and resistors for identical parts. Note: I am using a 220Ohm resistor
I also moved the position of where the jumper wires connect from the Arduino to the board, i.e. moved them up and down, and have done the same for the LED, resistor and other jumper wire. I have made sure that the LED cathode and anode are in the correct arrangement on the breadboard. I also made sure to push down on the components to make sure they made contact with the board.
When the GND and 5V aren't both connected to the breadboard at the same time, the "ON" led on the Arduino is solid red, and the "L" led is blinking. But when I connect both the jumper wires as below, those two led's stop emitting light. Is this normal behaviour?
I am a beginner so I probably messed up the wiring somehow. I would also very much appreciate any guidance on resources or methods on how to learn about electronics. If the wiring is fine, is it possible that the breadboard isn't working?
