Quick Steps. Connect Arduino to PC via USB cable. Open Arduino IDE, select the right board and port. Copy the above code and open with Arduino IDE. Click Upload button on Arduino IDE to upload code to Arduino. Press and keep pressing the button several seconds. See the change of LED's state. First, make sure to power off your Arduino - remove any USB cable. Plug a black wire between the blue line of the breadboard and a ground (GND) pin on the Arduino board. Plug the LED. You can notice that the LED has a leg shorter than the other. Plug this shorter leg to the ground (blue line here) of the circuit.
Arduinoer Arduino/Genuino 101 example to read button and turn ON/OFF LED
Connect three wires to the board. 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 third wire goes from digital pin 2 to one leg of the pushbutton. That same leg of the button connects through a pull-down resistor (here 10K ohm) to ground. How do you turn an LED on and off with a button on Arduino? We set the pinButton variable as integer 8 and we connect the button at pin 8 on the Board. Then the LED is connected to pin 2 using the resistor in series with it. In the setup() function we set the pin 8 as INPUT and pin 2 as OUTPUT. In the loop() function we read the value of the. Before you can do all of those things, you need to learn the basics! So let's start with simple: Use a button to toggle an LED! Wiring Diagram for the Button and LED. Let's start with a wiring diagram for this project. One thing to be aware of, many Arduino tutorials on buttons leave out the pull-down resistor attached to the button. Put Resistor 10k B/w Pin1 of Push Button and Gnd of Arduino; Pin2 of Push Button to 5V of Arduino ; STEP # 2 ( Make LED Connections ) +VE Of LED To D13 of Arduino. Resistor 470 B/w -VE Of LED & then Gnd of Arduino. STEP # 3 ( Upload Code ) Application. It can be used to turn on and off any device; It can be used as an indication of power.

Finally, you must select the right port for communication with your Arduino board. Once again from the menu, go to Tools > Serial Port, and select the right Serial port. On Macs, the correct serial port is often listed as /dev/tty.usbmodem1421 or similar. On Windows, the connection should be listed as a COM port. 2. One button will increase the brightness and another will decrease the brightness of the LED. Here you need to make a small circuit like below. Connect the two buttons input to the Arduino pin 12 and 13. Connect the LED +ve pin to Arduino pin 9 and the -ve pin to the ground using a current limiting resistor (220 Ω).
Build the circuit. Here is the circuit. How to build the circuit: First make sure that the Arduino is powered off (no USB cable plugged to anything). Check the LED, you will see that one of the leg is shorter than the other one. Plug the shorter leg of the LED to a hole on the breadboard. The toggle action means inverting the digital state of the output pin (or LED). To create an Arduino button toggle action, we'll follow the steps below: 1. Define an output pin (for the LED) 2. Define an input pin (for the push button) 3. Read the button input pin. 4.
