So I'm trying to create this interactive cuckoo clock where it's functioning normally through the use of servo and stepper motors and when activated by a PIR sensor the clock hands go backwards and the cuckoo bellows sound off. I've been able to get the sensor part of the code down but now I'm in a 2nd servo motor to act as the pendulum that moves underneath it.
The problem is now when I've added in the 2nd servo(myservo1, servoPin1), the stepper motor does not move. I don't believe it's a power thing because I have the stepper hooked up to its own 9v battery. The first motor which is activated by the PIR sensor works as it should, but it's only when I comment out the constant moving servo that the stepper motor works again. I've tried different placements of the servo part of the code but nothing has worked so far.
Help would be much appreciated!
// This Arduino example demonstrates bidirectional operation of a
// 28BYJ-48, using a ULN2003 interface board to drive the stepper.
// The 28BYJ-48 motor is a 4-phase, 8-beat motor, geared down by
// a factor of 68. One bipolar winding is on motor pins 1 & 3 and
// the other on motor pins 2 & 4. The step angle is 5.625/64 and the
// operating Frequency is 100pps. Current draw is 92mA.
