Has anybody been successful at getting an LED to work using code?
I have tried several examples that people have suggested but none of them work.
This is the last one I found:
led_controller = LEDController(“LED1”)
led_controller.set_led_effect(0, 1000, 5, 0b0001, 0xFF0000)
led_controller.timing_proc()
Do I have to add anything before or after this code to trigger it?
I am using a short click on a push button to trigger the code.
This will work.
Swap the 20 to 21 to swap between left and right connections.
import machine
import neopixel
pin = machine.Pin(20, machine.Pin.OUT)
np = neopixel.NeoPixel(pin, 4)
np[0] = (255,0,0)
np[1] = (0,255,0)
np[2] = (0,0,255)
np[3] = (255,255,255)
np.write()
It is important to note, the examples are extremely lacking and clearly little to no interest has been put in to help the community.
Thank you so much. I have been tearing what’s left of my hair out.
Nature beat me to that one.
I am a baldy.
Is there an LED off option in the code?
Yes, I gave it to you already, you are going to kick yourself.
You set the colours.
You set the colours, think about it.
As 255 is 100% on, 0 is 100% off.
When you turn all three triplet values to zero, the LED has no illuminated light.
DOH . It has been a longer day than I thought 
Does this work for 2 lights? If not, how do I make it work for 2 lights?
Assuming you mean two hubs, then you have everything there you need to write it for two, prepare to go doh!
import machine
import neopixel
// hub 1
pin = machine.Pin(21, machine.Pin.OUT)
np = neopixel.NeoPixel(pin, 4)
np[0] = (255,0,0)
np[1] = (0,255,0)
np[2] = (0,0,255)
np[3] = (255,255,255)
np.write()
// hub 2
pin = machine.Pin(20, machine.Pin.OUT)
np = neopixel.NeoPixel(pin, 4)
np[0] = (0,0,255)

np[2] = (255,0,0)
np[3] = (0,0,0)
np.write()
Que codigo es el que se usa? MicroPython?
Hello! I am a complete beginner with this system and wanted to ask if there is a way to make the LEDs flash alternately in blue and red? I am looking for a code that I can enter 1:1 into the code in the Cyberbrick software. At the moment, I can only set one effect at a time, but unfortunately not a sequence.
In my case, I have the LED strip on LED2 and only 2 LEDs on positions 1+2. Is there anyone who can help me with this? Thank you very much.

Hi what i did wrong it did not work i try when i long press the button that is connect on k1 to start my 2led on 0 and 1 on the ws2812 to flash red and blue then when press again it will turn off. this is my code i try to use but didnt work. thx
import time
import machine
import neopixel
PIN_NUM = 4 # Pin connected to the LED data line (NeoPixel)
NUM_LEDS = 4 # Number of WS2812 LEDs to flash (2 LEDs)
BUTTON_PIN = 6 # GPIO pin for K1 button on the transmitter (change accordingly)
pin = machine.Pin(20, machine.Pin.OUT)
np = neopixel.NeoPixel(pin, 4)
button = machine.Pin(6, machine.Pin.IN, machine.Pin.PULL_UP) # Assuming pull-up resistor
def set_color(led, r, g, b):
np[led] = (r, g, b)
np.write()
def flash_leds():
while True:
set_color(0, 255, 0, 0) # Red on first LED
set_color(1, 0, 0, 255) # Blue on second LED
time.sleep(0.5) # Flash delay
set_color(0, 0, 0, 0) # Turn off first LED
set_color(1, 0, 0, 0) # Turn off second LED
time.sleep(0.5) # Flash delay
# You can add a condition to stop flashing or break after a time if needed.
while True:
button_pressed = not button.value() # Button is pressed when value is low (active low)
if button_pressed:
# Start timer to check if it's a long press
press_start_time = time.ticks_ms()
# Wait until button is released or time exceeds long press threshold
while not button.value(): # Still pressed
if time.ticks_ms() - press_start_time > 2000: # Long press threshold (2 seconds)
# Trigger long press action (start flashing LEDs)
flash_leds()
break
time.sleep(0.05) # Small delay to avoid constant checking
# If the button is not pressed, just continue with regular actions or colors
time.sleep(0.1)
A couple of questions:
sorry i am new too this i try to use chat gpt to program it but did not work. but i wa able to make it work with this code but its always on now i want to integrate a button too it
import machine

As a general note, LLMs don’t give very good output for cyberbrick. This is because they try to treat them like standard ESP32 devices - even with lots of coaxing and instruction.
The ESP32 ecosystem is large and CyberBrick is much smaller - as a result, LLMs will probably cause you more issues than they will help. As an alternative, I would recommend reading through the API documentation for CyberBrick.
If your project requirements differ quite a bit from what cyberbrick offers, you may be better served by using a general purpose board. I love CyberBrick but it’s not always going to be the most appropriate choice for every project.
If you are staying within the cyberbrick ecosystem, I find that it works best to start from visual configuration for inputs and outputs in the UI. If you can’t accomplish what you need with those visual tools, try using code snippets with the absolute bare minimum actions taking place in each snippet. Note that each snippet runs in isolation and without global variables.
ok thanks for the advice. I will check on this

Hello dear community!
Today a post about controlling LEDs in the CyberBrick PC App with ‘Shippets’ as event modules in the Code (Beta) section…
Explanation first:
My problem was controlling the LEDs of an RC car with turn signals and headlights/taillights. In the CyberBrick App (PC), the lights would always turn off when blinking and couldn’t be controlled independently. Hence the attempt to control them accordingly using code.
Since this is only possible in CyberBrick in an ‘event-based’ manner, the possibilities to realize this with MicroPython were difficult and limited.
Especially since I wanted to ensure that the lighting and turn signals work with both lights on and off (the challenge here was checking the preconditions / middle LEDs on/off)
I’m happy to share the ‘Shippets’ here to perhaps save others with similar challenges the work.

# Set LEDs MANUALLY

All shippets were assigned to corresponding ‘actions’ on the transmitter
(e.g. turn signals on 3-way switch / horn flash button / reverse light & brake light motor control / hazard lights button (long press))
Works quite decently so far,
except that the response time of the control is significantly slower which leads to a certain delay!
Nevertheless usable for lighting control. (Maybe someone with more experience has the possibility to optimize the code?)
That’s all from me about the CyberBrick App!

Very night to have the snippets with the logic. The snippets appear to work here. But I am a bit confused how you assigned them to the different buttons.
for example
thee way switch: 1: “Left turn signal” 0: ??? II: “Right turn signal”
L shoulder button: short hold: horn flash
How do you turn on/oof the lights?
