![dc motor_LI](https://europe1.discourse-cdn.com/arduino/original/4X/9/3/7/937a3eb974ced69cf375bcf454aaba6f0a33e125.jpeg) I did not connect the dark blue, light blue and orange wire. I only connected gnd, 5V and the motor. But the motor isn't working also this time. So the driver is broken, isn't it? ---

Take the Arduino out of the circuit when testing the driver chip then use jumpers to provide the control inputs to the driver ---

how can I use jumpers to provide input? ---

When you run the Arduino sketch it changes the state of the driver inputs. An example ```cpp digitalWrite(DIRA, HIGH); //one way digitalWrite(DIRB, LOW); ``` with the Arduino disconnected from the circuit you can do the same with breadboard jumpers. For instance, to do the same as the 2 lines of code above you would connect pin 7 of the driver to 5V, which is the equivalent of pin 3 of the Arduino taking it HIGH and connect pin 2 of the driver to GND, which is the equivalent of pin 4 of the Arduino taking it LOW. You also need to enable the driver by taking its pin 1 HIGH **IMPORTANT NOTE** : I am using the values in your sketch and circuit and I have not checked whether they are correct ---

Thanks for helping me 🙂. Sadly my motor is not responding. I will buy another l293d driver and check it if it works. ---

A bit late now, but op should also connect the other 5V of the ic....(pin16) ---

Late one, but if anyone hits this topic with the same problem - you need to connect the power supply (9V battery) to the Power Supply Module - and turn that on ![PXL_20240916_085858867](https://europe1.discourse-cdn.com/arduino/original/4X/5/3/1/531ab293ef6b390360b45998ae71c0d13d9bfd6d.jpeg) [Previous page](https://forum.arduino.cc/t/dc-motor-not-working/904653.md?page=1)
