Step 2: Now the second LED and resistor the same way. Make sure to use a 220 ohm resistor or you might damage the LED. For one set of LED and the Push button, when button is pressed LED is set ON and when the button is released, LED will be set OFF. Depending on the style of your pushbutton, they often fit well straddling the long trench that goes through the breadboard. Button is connected to pin 12 push. Just connect one terminal of the button to pin no. for the other set, its the opposite effect. This specific series focuses on getting started with Arduino, and covers core concepts like basic code structure, interfacing with sensors, actuators and more. Finally, attach pin 4 to the lower left pin of the button and one end of the 10K resistor. And 7 and 8 are the port number or pin numbers on Arduino Uno which we will be using to connect to the IN1 and IN2 of the relay module. Function 3: Turn on/off GREEN light. The first two, red and black, connect to the two long vertical rows on the side of the breadboard to provide access to the 5 volt supply and ground. The button is not so hard either. Connect Arduino to PC via USB cable. When the button is closed (pressed), it makes a connection between its two legs, connecting the pin to 5 volts, so that we read a HIGH. See How To.
