How to solder LED's to PCB with resistor?
I basically have a PCB on which I have want to solder LEDs (and provide 270k ohm resistor protection). I just learnt basic soldering stuff and soldered a LED and a resistor on the PCB, but don't have clue about the connection to be made for the circuit. Neither does the above project which I surmised as a good starting point mention about any circuit diagram, and further its connections with the Arduino.
Can somebody point out how do I connect a simple LED and resistor in a circuit? [Current image attached]
And in the context of the above project that I am following, how do I create the circuit and connect with the Arduino?
