# Button
## read()
**Syntax:**
```arduino
uint8_t read();
```
**Description:**
This function returns reading the state of the button directly. 1: pressed, 0: released.
**Sample:**
```arduino
#include <M5Stack.h>
void setup() {
M5.begin();
}
void loop() {
M5.Lcd.setCursor(0, 0);
M5.Lcd.print("Button A Status: ");
M5.Lcd.println(M5.BtnA.read());
}
```
## isPressed()
**Syntax:**
```arduino
uint8_t isPressed();
```
**Description:**
This function returns the state of the button the last time Button.read() was called. 1: pressed, 0: released.
**Sample:**
```arduino
#include <M5Stack.h>
void setup() {
M5.begin();
}
void loop() {
M5.update(); // need to call update()
M5.Lcd.setCursor(0, 0);
if (M5.BtnA.isPressed()) {
M5.Lcd.printf("A button is pressed.");
} else {
M5.Lcd.printf("A button is released.");
}
}
```
## wasPressed()
**Syntax:**
```arduino
uint8_t wasPressed();
```
**Description:**
This function returns 1 only once each time the button is pressed. 1: pressed, 0: released.
**Sample:**
```arduino
#include <M5Stack.h>
void setup() {
M5.begin();
}
void loop() {
M5.update();
M5.Lcd.clear();
M5.Lcd.setCursor(0, 0);
if (M5.BtnA.wasPressed()) {
M5.Lcd.printf("Button A was pressed.");
delay(1000);
}
}
```
## pressedFor()
**Syntax:**
```arduino
uint8_t pressedFor(uint32_t ms);
```
**Description:**
This function returns 1 if button has been pressed for more than specified time. 1: pressed, 0: released.
| argument | description | type |
| --- | --- | -- |
| ms | pressing time (ms) | uint32_t |
