Guidance required for schematics from a sketch for bike lighting

Projects General Guidance

Hello Everyone,

I was searching for some ideas about lighting my bike and then I came across a video in youtube. The creator has uploaded a sketch and a video but the schematics is not available. I've gone through the sketch but unable to formulate a connection pattern as how they connected to make it work.

He is using 16 led neopixel and arduino.

I am attaching the video and the sketch for reference

Thank you in advance. It will be of much help if schematics is drawn.

All the wiring is defined in the sketch, no need for anything more, the inputs and outputs are defined. :wink:

POV spoke lighting is also cool, they will see you very well from the side and you can do pics & text.

I remember one bike light long ago that shined down and put the bike in a pool of light, easy to spot.

hi Larry. Thats exactly I am confused about . All neopixel strip has 3 pins. 5v, gnd & data. Only the data pin can be connected to the output of arduino. But in the arduino sketch the output is defined in various pins such as D2, D4, D9, D10, D11, D12 and D13. I wanted to know in which output pin of the arduino is used to connect the data pin of neopixel

As per your sketch:

int FD_OPin = 2; //Front Digital
int RD_OPin = 4; //Rear Digital
. . .
Adafruit_NeoPixel strip_rear = Adafruit_NeoPixel(REAR_NUM_LEDS, RD_OPin, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip_front = Adafruit_NeoPixel(FRONT_NUM_LEDS, FD_OPin, NEO_GRB + NEO_KHZ800);

2 strips using FD_OPin and RD_OPin

thanks a lot .
