8 Pieces 8 * 8 Non Self-locking Button, Switch

Description

What it is

This product is a series of eight 8×8 square buttons without self-locking functionality. The buttons are suitable for user interfaces in various electronic projects.

Features

• 8×8 square button
• Without self-locking functionality
• Number of pieces: 8

What it is for

The buttons are ideal for Arduino projects or other electronic systems where user action detection is required. They can be used in control interfaces, simple home alarms, or any other system that requires user input.

Tutorial: How to use 8×8 button without locking

This 8×8 button without locking is ideal for electronic control projects where user action detection is required. It is particularly useful for Arduino beginners who want to explore button-based interface programming.

What you need

• Arduino Uno or compatible
• USB Type B cable
• Connect to computer

Steps

1. Connect the 8×8 button to the Arduino circuit using the appropriate connectors for digital interfaces and power supply.
2. Check the correct polarity of the power supply voltage (5V or 3.3V) on the product datasheet.
3. Install the Arduino IDE on a computer and configure your Arduino Uno as a programming device.
4. Download or write a simple sketch that reads the state of the button and prints the result in the serial monitor.
5. Compile and run the sketch by uploading it to the Arduino.
6. Press the various buttons to see the response on the serial monitor of the Arduino IDE.
7. Check if all buttons work correctly and adjust the code based on the results obtained.

Example code

const int buttonPin = 2; // specificare il pin del pulsante
int buttonState;
void setup() {
  pinMode(buttonPin, INPUT);
}
void loop() {
  buttonState = digitalRead(buttonPin);
  Serial.println(buttonState);
}

Mini project

Create a simple home alarm system with multiple buttons that activate a flashing LED when one of the buttons is pressed.

Common mistakes

• Incorrect power supply polarity
• Incorrect Arduino pin for the button
• Can’t see the response on the serial monitor

Recommended accessories

• LED RGB 5mm
• Pull-up resistor
• Arduino Uno R3
• USB Type B connection

Frequently asked questions

Which pins should I use for the buttons?
Use any available digital pin on Arduino, but make sure they are configured as input in your code.

How can I add a sound alarm?
Add a siren or buzzer and connect it to one of the Arduino’s PWM output pins to control the alarm through the button.
