The PWM Pins are unnecessary if you do not want to control PWM features. Make sure you have all of your grounds tied together Arduino, Power source, and the Motor Controller. H-bridges are typically used in controlling motors speed and direction but can be used for other projects such as driving the brightness of certain lighting projects such as high powered LED arrays. EnA: Enables PWM signal for Motor A (Please see the “Arduino Sketch Considerations” section).The vehicle itself uses an Arduino UNO with an L298N motor driver. Control is via a DIY wireless controller using an Arduino and NRF24L01 modules. 5v: 5v input (unnecessary if your power source is 7v-35v, if the power source is 7v-35v then it can act as a 5v out) The vehicle is remote-controlled and the tank treads are partly from a VEX robotics tank tread kit.

The presented approaches cover the whole educative range from elementary school to university in both formal as well as informal settings.This L298 Based Motor Driver Module is a high power motor driver perfect for driving DC Motors and Stepper Motors. Evaluation results prove the impact of robotics on the students’ interests and competence development. This also involves the introduction of technologies ranging from robotics platforms to programming environments and languages. Researchers and educators will find valuable methodologies and tools for robotics in education that encourage learning in the fields of science, technology, engineering, arts and mathematics (STEAM) through the design, creation and programming of tangible artifacts for creating personally meaningful objects and addressing real-world societal needs. The wider the pulses, the faster the motor rotates. The speed of the motor will vary according to the width of the pulses. All you need is feed PWM signals to the motor enable pins. This proceedings book comprises the latest achievements in research and development in educational robotics presented at the 11th International Conference on Robotics in Education (RiE), which was carried out as a purely virtual conference from September 30 to October 2, 2020. Speed control is also possible with the L298N motor driver.
