I have a toy I am modifying for my son after he accidentally broke it. the new light in the toy has 3 color cycle functions (using a NewPixle 12 ring), that part works fine. I am trying to use the buttons on the toy (testing with my own buttons on a breadboard).
I have the "Void loop" setup to step through a bunch of "if" statements and act or not act accordingly. the issue is that at the step where the code checks the state of a "timer" variable I have written it appears to set the timer back to zero.
I have some serial monitoring going on so I can see where it happens, but I cant sort out WHY, probably something simple I am missing, that or I am taking the total wrong approach, I am fairly new to Arduino and I am not a programmer by trade, so I am learning a lot as I go.
Code:
#include <Adafruit_NeoPixel.h>
#define PIN 6
// Parameter 1 = number of pixels in strip
// Parameter 2 = Arduino pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
Adafruit_NeoPixel strip = Adafruit_NeoPixel(12, 3, NEO_GRB + NEO_KHZ800);
// IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across
// pixel power leads, add 300 - 500 Ohm resistor on first pixel's data input
// and minimize distance between Arduino and first pixel. Avoid connecting
// on a live circuit...if you must, connect GND first.
int buttonApin = 8; //Setup buttonA on pin 8
int buttonBpin = 9; //Setup buttonB on pin 9
int buttonCpin = 10; //Setup buttonC on pin 10
int buttonONpin = 11; //Setup buttonON on pin 11
int pwrPin = 12; //This is the pin tht will give power to the neopixle ring
int buttonOnState = 0;
