Using Arduino and L298N to control Tamiya Twin Motor Gearbox
I've connected the L298N to one of the motors of the Tamiya Twin Gearbox as per the circuit diagram in the L298N data sheet. But when I set pin 10 and pin 12 to go forward or reverse, nothing happens. The voltage at pin 13 and pin 14 seems to be equal to each other regardless of what I set for pin 10 and pin 12 (with the enable pin on high). This is the Arduino code I have. The diodes I am using are IN4007. I've also tried it with the other H-Bridge and I get the same result. I'm powering the L298N (Vss) through the Arduino 5V output and the motor (Vs) through 4 Ni-MH 1.2V batteries in series. Does anyone know what I am doing wrong?
int pin_11 = 2;
int pin_12 = 3;
int pin_10 = 4;
