how to control l298n motor driver from raspberry pi

The L298N can be powered from 5V to 35V (depending on the specification).īut it is important to note that if you power it with more than 12 volts the onboard 5V voltage regulator will be damaged. But in case they are missing or not set, you should verify their placement before proceeding. This type of board is usually shipped with three jumpers already in place. These instructions are based on the silkscreen of the board that I have. Attach an M2.5 standoff with two flat ends underneath.Hold the screw in place with your finger.From the top of the board, put an M2.5 screw through a hole on the corner of the board.But it reduces the chance of shorting if you place the board on metal or spill something on to the work surface. Make sure the wheels aren't touching the supporting wheel.Make sure that the wires are closer to the middle.

Use the standoffs to hold the two motors together.If you have a 3D printer, clamp, helping hands or some spare parts you can design something a bit more stable. This is a quick way of putting together a rig that won't roll away while testing. You can buy the parts for this article by following my affiliate links to either Amazon or AliExpress: Part I'll provide a quick demo program so you can see how to run the motors through a predefined sequence. In the second part I will show you how to quickly wire up the driver to an Arduino. It should also give you ideas for very simple robot projects. This will give you a better understanding of how a motor driver works. In the first part I will show you how to control the driver without the need for a computer. Most motorized toys and many robot chassis kits use simple DC motors. In this tutorial I cover how to drive two DC (direct current) motors using an L298N motor driver.
