DC Motor Control Using Joystick

This is a compact, low-profile, and high-performance DC motor driver that provides easy control of a DC motor using a joystick. This small-size board can drive small to medium-sized brushed DC motors with up to 2.5A continuous and 6A peak currents. It is an Arduino-compatible project that helps users develop their own code and drive DC brushed motor as per application requirements. The Arduino-compatible hardware consists of an ATMEGA328 microcontroller and IFX9201 H-Bridge chip.

Selecting a DC motor

The project can drive small DC motors with peak currents of up to 6 A. The achievable continuous drive current is lower and depends on supply voltage, switching frequency, and cooling conditions. Realistic continuous drive currents for this project are in the range of 1 A to 2.5 A. Many motors for toys, RC models, or robotics fall in this range.
