5-way Tactile Button Breakout Board

Description

5-way tactile switch board

Description: Sometimes a very small directional input device is needed (the world’s smallest game controller, anyone?) This 5-way tactile switch (up, down, left, right, and center click) allows joystick-like control in a very small package. This breadboard-compatible board interrupts all switching signals and includes pull-up resistors configured so that the outputs read low when pressed and high otherwise. (If desired, you can invert the power leads for pull-down operation.)

Tutorial: How to use 5-way Tactile Switch Breakout Board

This 5-way tactile switch is ideal for projects requiring precise directional control in a small space. Useful for beginner and intermediate makers.

What you need

• 5-way Tactile Switch Breakout Board
• Arduino or compatible microcontroller
• Power supply cable
• Pull-up resistor (if needed)

Steps

1. 1. Connect the board to your microcontroller using breadboard pins.
2. 2. Connect the VCC and GND pins to the microcontroller.
3. 3. Connect the up, down, left, right, and click pins to the microcontroller.
4. 4. Configure the pins as input with pull-up on Arduino.
5. 5. Load the example code to control the buttons.
6. 6. Check the datasheet for specific parameters.
7. 7. Try pressing the buttons and verify the signals.
8. 8. Adapt the code to your specific needs.

Example code

```cpp
int up = 2; int down = 3; int left = 4; int right = 5; int center = 6;
void setup() {
  pinMode(up, INPUT_PULLUP); pinMode(down, INPUT_PULLUP);
  pinMode(left, INPUT_PULLUP); pinMode(right, INPUT_PULLUP);
  pinMode(center, INPUT_PULLUP);
}
void loop() {
  if (digitalRead(up) == LOW) {
    Serial.println("Su");
  }
  if (digitalRead(down) == LOW) {
    Serial.println("Giù");
  }
  if (digitalRead(left) == LOW) {
    Serial.println("Sinistra");
  }
  if (digitalRead(right) == LOW) {
    Serial.println("Destra");
  }
  if (digitalRead(center) == LOW) {
    Serial.println("Clic");
  }
}
```

Mini project

Create a simple joystick using touch buttons on an LCD display.

Common mistakes

• Forget to configure the pins as input pull-up.
• Incorrectly connect the VCC and GND pins.
• Omit checking the datasheet for specific parameters.
• Do not test the buttons before loading the code.

Recommended accessories

• LCD display
• Breadboard
• Connection wires
• Pull-up resistor

Frequently asked questions

How can I invert the output signals?
Invert the power supply cables VCC and GND on the datasheet.

Which pins should be used to control the buttons?
Use pins 2, 3, 4, 5 and 6 to control the up, down, left, right and click buttons.

Is the pull-up resistor necessary?
Yes, it is necessary to read the button signals correctly.
