The L293D motor driver is designed to handle the motor currents as specified, so the Arduino does not see the load the motors present to the L293D IC. The IC is both a buffer and driver, with outputs that can be shut off. (high-impedance) | |
| Jul 5, 2016 at 19:05 | comment | added | John Am | Thanks for the info. I'll have to study what happens in power on of the whole circuit. Now i start the Arduino and after i upload the program i connect the power supply to the motors. | |

The input pins for the L293D draw almost no current, so that is why I suggested the 10K pull-down resistors to act as a minimum load and keep the IC and motors OFF (high-impedance) until your software can control the I/O pins during boot-up. | |
