Hi guys,
I am trying to control a 16 LED neopixel ring alongside a 5v servo on an arduino flora with 4xAAA batteries (because I know the pixel ring and servo need 5v to work). I have previously made my servo and the neoring separately from each other on the flora and I know I need to use this code (https://learn.adafruit.com/trinket-gemm ... ntrol/code) however when I turn the batteries on the servo does not work and the LED's flash momentarily then turn off.
Can anyone provide advice for what I am doing wrong?
Thanks!
Maggie

Could you post the code you are having trouble with?

Re: Neopixel ring and servo on a flora
Code: Select all
#if defined(__AVR_ATtiny85__)
#error "This code is for ATmega boards, see other example for ATtiny."
#endif
#include <Adafruit_NeoPixel.h>
#include <Adafruit_TiCoServo.h>
// NeoPixel parameters. These are configurable, but the pin number must
// be different than the servo(s).
#define N_LEDS 60
#define LED_PIN 6
#define SERVO_PIN 9
#define SERVO_MIN 1000 // 1 ms pulse
#define SERVO_MAX 2000 // 2 ms pulse
Adafruit_NeoPixel strip = Adafruit_NeoPixel(N_LEDS, LED_PIN);
Adafruit_TiCoServo servo;
void setup(void) {
servo.attach(SERVO_PIN, SERVO_MIN, SERVO_MAX);
strip.begin();
}
void loop(void) {
int a, x;
a = analogRead(0); // 0 to 1023
x = map(a, 0, 1023, SERVO_MIN, SERVO_MAX); // Scale to servo range
servo.write(x); // Move servo
x = map(a, 0, 1023, 0, strip.numPixels()); // Scale to strip length
strip.clear();
while(x--) strip.setPixelColor(x, 255, 0, 0); // Set pixels
strip.show(); // Update strip
}

Re: Neopixel ring and servo on a flora
Could you post clear, detailed pictures of both sides of your board showing any soldering you have done and the connections to it?
