Build your very own


As we’ve seen and read through with our interaction on the topic Secret life of Motor Drivers, is that as the inventions came up, they continued evolving and with such good reason. With each proving its exception in the field be it with precision in torque, speed control and position.

As they have evolved over the decades, all these different forms of motor drivers have been able to be applied through so many functions. All round from students doing tailored projects to hobbyist having a thrill at the world of availed possibilities in all matters motion. We are talking from the L293D a substitute to the L298N



To the L298N;

To the Servo Motor;

The Stepper Motor Controller;

All of this which when put together each by each and/or with other components become even valuable in function as in it is in action. Now that we know what they are, how they came to be, let us check out a couple of ideas that will definitely help broaden the specs of what you thought they might be limited to do, alongside the various other components they can be coupled with.


  1. The Direct Current motor driver (DC motor)

Remember what this does?? Well, it allows speed and direction control of two DC motors at the same time. See the case in point, An obstacle avoidance robot;

To be precise a 2-wheel Robot obstacle avoidance car. Clearly marked you can see the L298N Motor driver and what is it controlling? 2 TT 130 accelerator/decelerator motors. Very simple and a straight to the point kind of project minimal components which as per the image include;

  • The L298N
  • An Arduino Uno or Mega
  • Breadboard
  • Jumper wires
  • Ultrasonic sensor
  • The 2-wheel drive robot chassis

All of which are available on the site, every component that will be in discussion, check them out on

There so many other projects to be tackled with the L298N; line following robot, Automation of model trains, Smart wheelchair, IR Remote controlled robot (which we just tackled in a training) Basically if speed needs controlling, dc motor driver is your best choice.

  1. Stepper Motor Driver.

Remember holding torque and positioning? How about a couple of pictorial examples of projects that you can try;

A ULN2003 stepper driver

How about a mini showcase, a platform that rotates clockwise, anti-clockwise as per coded input? You could put on a mini show for fitting projects, on display, ‘lights, camera, action? Check out an illustrative diagram and schematic of the same and all you’ll need; a stepper motor, the stepper motor driver, wooden base, aluminum mounting hub. We’ve got so many videos illustrated projects, go on right to our social media pages which, we will mention at the end of this blog.

A 3-axis Camera slider.

A really cool one for a try. Designed it for video motion control, time-lapses and panoramic shots. In it;

  • Arduino nano as the brain
  • Bluetooth module
  • Hall effects sensors and magnets.
  • 3 stepper motors controlled by their driver boards which in combination of the stepper’s step angle, the micro stepping mode of the driver boards and gear ratios of the pan and tilt axis, you get precision.


  1. The Servo Motor

When it comes to your options on torque, then this right here might be your best one yet. Now what is it we mean when we say torque? It basically means momentary force; the measure of how a force acting on an object, causes that object to rotate. Since torque is directly proportional to current, the servo controller obtains the actual motor current from the servo drive and uses this to determine actual motor torque. And torque determines the motor’s acceleration, which affects velocity and position. See reference of a servos opened up view on page 1.

Now that you know that how about we take a look at a really cool project that is not only fun but also addresses poses as a solution especially since we are all for renewable energy integrations.

A Servo-Controlled Light-Tracking Solar Panel Platform;

We have done this as a project a while back, the video illustration is on our social media platforms both Instagram and Facebook, Novatech_kenya and Novatech Engineering Solutions respectively. And for the project above It only took;

  1. 2 servo motors             5. Push button
  2. Photoresistor                6. Temperature sensor
  3. Arduino uno                  7. Resistors, Capacitors
  4. Solar panel


Those are just three very simple projects you could do to test out the driver’s functionalities and see for yourselves. There are so many other projects you could try, all ideally posted on our social media and as for the codes, we will have a separate file that has them all compiled for easy follow up and for a complete experience.
