![]() Part 5 of 5 - 3 Wire Direction Control, 1 PWM Speed Inverted Logic.Part 4a - 3 Wire Direction Control, 2 PWM pins for Speed Control.Part 4 of 5 - 3 Wire Direction Control, PWM on Enable pin for speed control.Part 3 of 5 - 3 Wire Direction Control (Enable Pin) No Speed Control.Part 2 of 5 - 2 Wire Direction Control and 1 PWM Pin speed using inverted logic.Part 1a - 2 wire direction and speed control using 2 PWM pins.Part 1 of 5 - 2 Wire Direction Control, not using PWM.(This will * drive one motor)Īnd at minimum 4 wires are needed for 2 DC motors. That is to say At a minimum you need 2 wires per DC motor. A 3 wire setup could be duplicated for 6 wires. ![]() SO for these demos, a 2 wire setup could be duplicated for 4 wires. ![]() The L298 can drive 2 DC Motors, these demos only use one motor, but can be duplicated on the remaining pins of the L298. ![]() IT was purposely left to not show complete code, but the code could be easy to duplicate to other pins for two motor use. It is left up to the student the method, or combination of methods they would like to use in their project (robot). This was put together, not to show a complete working two wheeled robot, but to attempt to explain the ideas behind the operation. The L298 is commonly found in hobby and educational robots. In this short series - I will attempt to show different methods for using the L298 H Bridge Motor Driver Board.
