Please input the desired speed of motor A ProgramName = TwoPwmCounters140709cThe method "PwmCounter" as been started in cog # 2 Here's a sample screen after motor A has been set to a speed of 2.
HOW TO KNOW IF L298N MOTOR DRIVER IS WORKING SERIAL
It uses the Parallax Serial Terminal as input. The second motor is disabled with the present settings. Note the enable and direction pins for the second motor are not set. ' Set IN4_PIN to -1 if using a single direction pin. ' Set IN3_PIN to -1 if no direction pin is used (when using a transistor).

' Set ENABLE_PIN_B to -1 if no direction pin is used (when using a transistor). ' Set IN2_PIN to -1 if using a single direction pin. ' Set IN1_PIN to -1 if no direction pin is used (when using a transistor).
HOW TO KNOW IF L298N MOTOR DRIVER IS WORKING CODE
The code attached to this post uses the following I/O pin assignments. This latest version included hookup diagrams for the ebay L298N PCBs shown in the tutorial video. Program "TwoPwmCounters140905a" uploaded September 5, 2014. Program "TwoPwmCounters140904a" deleted Septem(0 views). Program "TwoPwmCounters140904a" uploaded September 4, 2014. If any of you are using this previous version, make sure and switch to the latest code. There was a bug in the program "TwoPwmCounters140709c", which prevented it from working correctly if any of the pins were set to -1. Program "TwoPwmCounters140709c" deleted Septem(20 views). Program "TwoPwmCounters140709c" uploaded July 9, 2014. Please wait to comment until I've make three additional posts to this thread.
HOW TO KNOW IF L298N MOTOR DRIVER IS WORKING SOFTWARE
I'll reserve a few posts (3 more) to use for software and other information. I plan to add some additional material to this thread. If one switched both the motor wires and the "IN" wires, you'd be back where you started. Of course only one method (or an odd number of methods) should be used to reverse the direction of the motor. These can be either physically swapped, or the I/O pins can be switched in the program. If a motor is spin in the opposite direction of the desired direction, there are several ways to reverse the direction of the motor.īy switching with wire is connected to which screw terminal, the motors will be reversed. Here's a table of how the pins should be set to achieve forward and reverse motor control.Ĭoast Low X X "X" means it can be high or lowīrake High Low Low (If both IN1 and IN2 are high, it will also brake)įorward and reverse are pretty much chosen arbitrarily. Apparently higher voltages can also cause trouble for the microcontroller attached to the board ( as erco found out for himself). The L298N can use voltages as high as 46V but the regulator can't take this high of a voltage. The battery high limit of 14V is to keep the 5V regulator from being burned out. Here's a photo to which I added some diagrams on how the board should be connected to a microcontroller. IMO, it's very helpful to get straight how the pins need to be set before attempting to use a h-bridge with a microcontroller. Setting the control pins high and low is something one could also do with more expensive h-bridges. I hope by seeing how the pins need to be set, a newcomer to hobby robotics will have a better understanding of what the software needs to do to control the h-bridge. I show how one can control the h-bridge by setting the enable and direction pins directly without using a microcontroller.

Over 14 minutes (though it's shorter than TheRaspberryPiGuy's how to fry pi video). At these prices, it's hard to resist purchasing a few of these inexpensive h-bridges. You could probably purchase ten or more L298N boards (shipped) for the price of a single MC33926 board. The main (only?) advantage the L298N boards have is they are dirt cheap on ebay. Parallax sells the MC33926 dual h-bridge board made by Pololu which would be a much better alternative to the L298N. There are lots of better h-bridges than the L298N. Several people I consider robot experts ( Gordon McComb and Russell Cameron) have mentioned their dislike of the chip on several occasions. Even 5V microcontrollers would likely be damaged if used the way the video suggests.įirst off (as I say in the video) the L298N quad half bridge is a really poor choice as an h-bridge.

The TRPG's video has likely contributed to many burned out Raspberry Pi computers. After seeing TheRaspberryPiGuy's video titled " Raspberry Pi - How to control motors." and seeing the Pi's I/O pin being connected to a 5V pin, I decided to make my own tutorial video.
