6 Non Self-locking Buttons, 8.5 * 8.5mm Double Gray Button Set

Description

What it is

Dark Gray Non Self-locking Push Buttons Sets are useful components for electronic projects as one learns to use Arduino. This set contains 6 pieces, each with dimensions of 8.5*8.5mm.

Features

• Set of 6 Dark Gray Non Self-locking Push Buttons
• Dimensions: 8.5*8.5 mm

What it is for

The buttons are ideal for projects that require interaction, such as creating a simple button counter using 3 of these buttons and an LCD display.

Tutorial: How to Use 8.5*8.5 Push Button

This button is ideal for projects that require interaction as one learns Arduino. Useful for beginners and intermediates.

What you need

• Arduino
• 10kΩ Resistor
• Power Cable

Steps

1. 1. Take the 6 push buttons and check the datasheet for specifications.
2. 2. Solder the push buttons onto a protoboard.
3. 3. Connect the push buttons to the Arduino input pin.
4. 4. Connect the resistor between the input pin and GND.
5. 5. Load the example code onto the Arduino.
6. 6. Try pressing the buttons and observe the onboard LEDs.
7. 7. Adapt the code to handle multiple buttons.
8. 8. Test the functionality with a custom program.

Example code

```
void setup() {
  pinMode(2, INPUT);
}

void loop() {
  if (digitalRead(2) == HIGH) {
    Serial.println("Pulsante premuto");
  }
}
```

Mini project

Create a simple button counter using 3 of these buttons and an LCD display.

Common mistakes

• Connect the button directly to GND without a resistor.
• Forget to load the code.
• Install the buttons on an unprotected circuit.
• Use an Arduino pin other than INPUT for the buttons.

Recommended accessories

• 16×2 LCD Display
• Protected Circuit
• Arduino UNO
• 5V Power Cable

Frequently asked questions
