Arduino L239D RC-Car


I want to build an Arduino car controller via Bluetooth and smartphone. My problem is that the RC-motors don't work as they should.
//Kann auch ENABLE EN1 und EN2
//L293 statt L293D, weil 1A statt 0,5A und wird weniger heiß, ist aber größer, die 0V in seiner Schematics ist Hitzeableiter
int IN1 = 12;
int IN2 = 13;
int schalter = 4;
int gas = 0;
void setup() {
pinMode(IN1, OUTPUT);
pinMode(IN2, OUTPUT);
}
void loop() {
digitalWrite(IN1, LOW);
digitalWrite(IN2, HIGH);
delay(2000);
digitalWrite(IN2, LOW);
delay(2000);
}
If I connect a battery directly to the motor, it spins. But over the L293D driver nothing works. But when I measure the outputs of the L293D that would be connected to the motor, the output is just fine.
