If no arguments are specified, toggle the state of all LEDs. N will result in this method never returning). Return when the blink is finished (warning: the default value of background ( bool) – If True (the default), start a background thread toĬontinue blinking and return immediately.fade_out_time ( float) – Number of seconds to spend fading out.fade_in_time ( float) – Number of seconds to spend fading in.Only work if the pwm parameter was True at construction time. Make all LEDs fade in and out repeatedly. Pulse ( fade_in_time=1, fade_out_time=1, n=None, background=True ) ¶

Parameters:Īrgs ( int) – The index(es) of the LED(s) to turn on. If blink() is currently active, it will be stopped first. on ( 1, 2 ) # turn on the middle LEDs (pins 3 and 4) leds. on ( - 1 ) # turn on the last LED (pin 5) leds. on ( 0 ) # turn on the first LED (pin 2) leds. Specified, they must be the indexes of the LEDs you wish to turn off.įrom gpiozero import LEDBoard leds = LEDBoard ( 2, 3, 4, 5 ) leds. If no arguments are specified, turn all the LEDs off. If False, only return when the blink isįinished (warning: the default value of n will result in this

background ( bool) – If True, start a background thread to continue blinking and.

n ( int or None) – Number of times to blink None (the default) means forever.

Pwm was False when the class was constructed

off_time ( float) – Number of seconds off.

on_time ( float) – Number of seconds on.

Make all the LEDs turn on and off repeatedly. You can also specify LEDBoard instances toīlink ( on_time=1, off_time=1, fade_in_time=0, fade_out_time=0, n=None, background=True ) ¶ Necessary and use any names, provided they’re not already in use by

**named_pins – Specify GPIO pins that LEDs of the board are attached to, associatingĮach LED with a property name.

pin_factory ( Factory or None) – See API - Pins for more information (this is an advanced feature.

True, the device will be switched on initially.

None, each device will be left in whatever state the pin isįound in when configured for output (warning: this can be on). initial_value ( bool or None) – If False (the default), all LEDs will be off initially.Set all pins to LOW (the off() method always does the opposite). active_high ( bool) – If True (the default), the on() method will set all theĪssociated pins to HIGH.Ifįalse (the default), construct regular LED instances. pwm ( bool) – If True, construct PWMLED instances for each pin.You can also specify LEDBoard instances to *pins – Specify the GPIO pins that the LEDs of the board are attached to.From gpiozero import LEDBoard leds = LEDBoard ( 2, 3, 4, 5, 6 ) leds.
