Project 2.5.2: LED Control with Arduino and Push Button

Description	You will learn how to create a simple circuit using an Arduino microelectronic and a push button.
Use case	Imagine you want to create an interactive lighting system for your living room using Arduino and push buttons. You want to control the ambiance by turning on specific lights with a simple press of a button

Components (Things You will need)

Building the circuit

Things Needed:

• Arduino Uno = 1
• Arduino USB cable = 1
• Resistor = 1
• Push button = 1
• Red LED = 1
• Blue jumper wire= 1
• Yellow jumper wire= 1
• Black jumper wire= 1
• Red jumper wire= 1

Mounting the component on the breadboard

Step 1: Take the breadboard and the red LED and insert the red LED into the vertical connectors on the breadboard. .

step 2: Connect the pushbutton on the breadboard but make sure the two pair of the pins are connected on each side of the bridge. .

step 3: Take one resistor and connect one terminal of the resistor to the longer pin of the LED positive terminal (+) on the breadboard and the other pin of the resistor into the vertical connected wholes on the breadboard. .

Note: NB: This completes the circuit for the LED, allowing current to flow from the digital pin, through the LED and back to ground.

WIRING THE CIRCUIT

Things Needed:

• Blue jumper wire= 1
• Yellow jumper wire= 1
• Black jumper wire= 1
• Red jumper wire= 1

step 1: Connect red male-to-male jumper wire from the free end of the resistor to digital pin (13) on the Arduino UNO. .

step 2: Connect Black male-to-male jumper wire from the free end of the LED negative pin power GND (Ground) on the Arduino UNO. .

step 3: Connect Yellow male-to-male jumper wire from one Pin of the Push Button as a negative to power GND (Ground) on the Arduino UNO. .

step 4: Finally, connect blue male-to-male jumper wire from the other Pin of the push button (not connected to GND) to any digital pin on the Arduino UNO. Let's use digital pin 2 in this tutorial. .

PROGRAMMING

Step 1: Open your Arduino IDE. See how to set up here: Getting Started.

Step 2: Type the following codes before the void setup function.

const int ledPin1 = 3;
const int buttonPin = 2;
bool isBlinking = false;

.

Step 3: After the void setup ()within the curly brackets type the following codes.

pinMode (LedPin1, OUTPUT); 

.

Step 4: : After the (void loop ()) within the curly brackets type

  if (digitalRead(buttonPin) == LOW && !isBlinking) {
    isBlinking = true;
    while (digitalRead(buttonPin) == LOW) {
      digitalWrite(ledPin1, HIGH);
      delay(500);
      digitalWrite(ledPin1, LOW);
      delay(500);
    }
    isBlinking = false;
  }

.
