| L298 Pin | Connected to | |----------|-----------------------------| | IN1, IN2 | Arduino D8, D9 (direction) | | ENA | Arduino D10 (PWM) | | OUT1,2 | DC motor terminals | | VS | 12V | | VSS | 5V | | GND | Common GND |
You forgot to connect the Vss (Motor Voltage) pin or GND pin. Fix: l298 motor driver library for proteus download
Because of its popularity, having a working simulation model in Proteus saves significant prototyping time. IN2 | Arduino D8
