Auger for 28BYJ-48 driven Fish Feeder

The auger that comes with the excellently designed original didn't work for me in my small tank with 7 guppies as it was really hard to control the flow of food in such small amounts. I created a new auger with a much lower pitch so it has 11 rotations rather than the original 4. I'm able to finely adjust the Arduino code now to reliably put out what I want.Full credit to the original creators, this is just a minor tweak on an otherwise brilliant feeder.Code below for what I use with the Wemos D2 at the moment#include #define HALFSTEP 8// Motor pin definitions#define motorPin1 15 // IN1 on the ULN2003 driver 1#define motorPin2 13 // IN2 on the ULN2003 driver 1#define motorPin3 12 // IN3 on the ULN2003 driver 1#define motorPin4 14 // IN4 on the ULN2003 driver 1// Initialize with pin sequence IN1-IN3-IN2-IN4 for using the AccelStepper with 28BYJ-48AccelStepper stepper1(HALFSTEP, motorPin1, motorPin3, motorPin2, motorPin4);void setup() {stepper1.setMaxSpeed(500);stepper1.setAcceleration(50);stepper1.setSpeed(500);stepper1.move(500);stepper1.runToPosition();stepper1.move(-4000);stepper1.runToPosition();stepper1.move(500);stepper1.runToPosition();}//--(end setup )---void loop() {}
