We test it as Video, first type code on IDE without “delay” command. PinMode(buttonPin, INPUT) // initialize the pushbutton pin as an input:īuttonState = digitalRead(buttonPin) // read the state of the pushbutton value:ĭigitalWrite(ledPin, HIGH) // turn LED on:ĭigitalWrite(ledPin, LOW) // turn LED off: PinMode(ledPin, OUTPUT) // initialize the LED pin as an output: Int buttonState = 0 // variable for reading the pushbutton status Int ledPin = 13 // the number of the LED pin Next, the Output is Digital PIN 13 connected to LED by 470 ? resistor to limit current.įigure 3 Simple Button Digital Input using Arduinoįigure 4 the Simple Button Digital Input code with delay int buttonPin = 3 // the number of the pushbutton pin This circuit use Pull-Down by connect the Button to 5V power supply and 10K resistors to ground. Step 2 connect the parts as circuit Figure 2 The circuit connection By using the Pull-Down to apply LED grow up when we press the button only. We will use the Input Pin of Arduino to receive the button status, then control LED display on Output Pin 13. This resistor Pull-Up / Down Resistor used the 5K – 20K. We will see that 2 circuits have the operation reversed.

If you have any question regarding code or circuit connection feel free to leave a comment. We hope you’ll enjoy working with Arduino as it’s very easy to use hardware. In next few tutorials, we’ll explore the use of GPIO pins to serve different purposes. This is how we can interface LED and Switch with Arduino Uno. Val = digitalRead(switchPin) // read input value PinMode(switchPin, INPUT) // declare pushbutton as input PinMode(ledPin, OUTPUT) // declare LED as output Int val = 0 // variable for reading the pin status #define switchPin 7 // choose the input pin (for a pushbutton) Here is a circuit connection we need to do before uploading the sketch.Ĭonnection Switch with Arduino Uno Program Switch to Arduino Uno #define ledPin 13 // choose the pin for the LED The reason is because it’s an active low pin. Make sure while connecting switch we will have to use pull up resistor of value 1K to 10K. The Switch will be connected to PIN 7 of Arduino. In this example project we have to connect LED to PIN 13 of Arduino. Let’s add button switch to our previous project and turn LED ON/OFF using Switch. Now It’s time to learn how to configure Arduino Pin to INPUT Mode.
the loop function runs over and over again foreverĭigitalWrite(13, HIGH) // turn the LED on (HIGH is the voltage level)ĭigitalWrite(13, LOW) // turn the LED off by making the voltage LOWĪfter connecting LED and configuring Arduino pin into OUTPUT mode.
initialize digital pin LED_BUILTIN as an output.
Connection LED with Arduino Uno Program Blink LED with Arduino // the setup function runs once when you press reset or power the board And later on, we will use PIN 7 to configure as input and learn how to interface switch to control the LED. One in which we will connect LED to PIN 13 of Arduino and blink it after every second. Now in this tutorial, we have presented two examples. Arduino Uno has 14 digital I/O Pins which will be referred as GPIO. Here we will explore how to interface LED and Switch with Arduino Uno. This tutorial is about the programming of GPIO Pins.
