Tutorial: How to use Y090LAY7-11

The mushroomhead push button switch Y090LAY7-11 is ideal for projects requiring a physical switch. Useful for beginners and intermediate makers.

What you need

• Mushroomhead push button switch Y090LAY7-11
• Arduino
• Power supply cable
• 10kΩ resistor
• Breadboard

Steps

1. 1. Mount the push button on the breadboard.
2. 2. Connect the positive terminal of the push button to the digital input pin of the Arduino.
3. 3. Connect the negative terminal of the push button to GND.
4. 4. Connect a 10kΩ resistor between the digital input pin and VCC.
5. 5. Download the following code to the Arduino.
6. 6. Connect the Arduino to the power supply.
7. 7. Test the button.
8. 8. Verify the button reading on the serial monitor.

Example code

```void setup() {  pinMode(2, INPUT);  Serial.begin(9600);}void loop() {  int val = digitalRead(2);  Serial.println(val);  delay(100);}```

Mini project

Create a simple counter using the button. Connect the button to a digital pin and an LED to another. Each time you press the button, the LED should turn on and off.

Common mistakes

• Do not check if the button is properly connected.
• Omit the pull-up resistor.
• Do not use the `digitalRead` function.
• Forget to connect the power supply.

Recommended accessories

• LED
• LED resistor
• Breadboard
