I am very new to Arduino. I followed a tutorial for L293D + DC motor on youtube where the instructor connected the power supply module (because he said Arduino can't power the DC motor) to the Vs pin (pin 8 ) on the L293D and three digital pin on the Arduino board to the enable, input1 and input2 pins on the L293D. All the grounds are shared. However, if I try the configuration on tinkerCAD, it complains that voltage at enable1 (5v) is higher than voltage at Vcc(0v). The example on tinkerCAD has an extra connection from the 5V pin on the arduino board to Vss pin on L293D. Was the youtube instructor wrong? Would it fry the IC?
