1. Motors twitch but don't spin.

2. Arduino resets when motors start.

3. Overheating.

const int IN1 = 2;    // direction pin 1
const int IN2 = 3;    // direction pin 2
const int ENA = 5;    // PWM pin (must be PWM-capable)
void setup() 
  pinMode(IN1, OUTPUT);
  pinMode(IN2, OUTPUT);
  pinMode(ENA, OUTPUT);
void loop() 
  // Forward at 75% speed
  digitalWrite(IN1, HIGH);
  digitalWrite(IN2, LOW);
  analogWrite(ENA, 191); // 0-255 -> 191 ≈ 75%
  delay(2000);
// Stop
  analogWrite(ENA, 0);
  delay(500);
// Reverse at 50% speed
  digitalWrite(IN1, LOW);
  digitalWrite(IN2, HIGH);
  analogWrite(ENA, 128);
  delay(2000);
// Stop
  analogWrite(ENA, 0);
  delay(500);

Connect stepper coils:

Driving sequence: standard 4-step or 8-step sequence using digitalWrite to D12, D11, D8, D7 and PWM to D5, D6, D9, D10. Connect Power:
