By default the heartbeat LED flashes in blue colour once every 4s to signal that the system is alive. This can be overridden through the `pycom` module.
|
|
|
|
```python
|
|
import pycom
|
|
|
|
pycom.heartbeat(False)
|
|
pycom.rgbled(0xff00) # turn on the RGB LED in green colour
|
|
```
|
|
|
|
The heartbeat LED is also used to indicate that an error was detected.
|
|
|
|
The following piece of code uses the RGB LED to make a traffic light that runs for 10 cycles.
|
|
|
|
```python
|
|
import pycom
|
|
import time
|
|
|
|
pycom.heartbeat(False)
|
|
for cycles in range(10): # stop after 10 cycles
|
|
pycom.rgbled(0x007f00) # green
|
|
time.sleep(5)
|
|
pycom.rgbled(0x7f7f00) # yellow
|
|
time.sleep(1.5)
|
|
pycom.rgbled(0x7f0000) # red
|
|
time.sleep(4)
|
|
```
|
|
|
|
Here is the expected result:
