The module has several spare General Purpose Input-Output (GPIO) pins available for you to use with your own sensors and actuators.
|
|
|
|
## Output
|
|
Controlling the GPIO pins of the modules is rather easy. In the example below, we can let the orange LED on the expansion board blink.
|
|
|
|
```python
|
|
from machine import Pin
|
|
import time
|
|
led = Pin('P9', mode=Pin.OUT)
|
|
|
|
while True:
|
|
print("high")
|
|
led.value(1)
|
|
time.sleep(1)
|
|
print("low")
|
|
led.value(0)
|
|
time.sleep(1)
|
|
```
|
|
## Input
|
|
|
|
Sometimes, it would be useful to know the state of a pin. For example, you could use the button on the xpansion board to toggle the led
|
|
|
|
```python
|
|
from machine import Pin
|
|
import time
|
|
led = Pin('P9', mode = Pin.OUT)
|
|
button = Pin('P10', mode = Pin.IN)
|
|
|
|
while True:
|
|
if(button() == 1):
|
|
led.value(1)
|
|
else:
|
|
led.value(0)
|
|
```
