About PlatformIO IDE

This is a Platform IO IDE project coded in C++.

Platform IO is a plugin for Microsoft Virtual Studio Code. It is a more robust IDE compared to official Arduino IDE which makes easy to create our own private libraries and use a better object-oriented design.

About the code

The parameters can be customized in the main.cpp

#define DEFAULT_SPEED 150   // Default motor speed for driving
#define PID_PGAIN 200       // PID Proportional
#define PID_IGAIN 0         // PID Integral
#define PID_DGAIN 0         // PID Derivative
#define PID_SERVO false     // PID Servo

About Car Chassis

This project was optimized for a 2WD car chassis. But a 4WD chassis can also be used by changing the motor speed and PID parameters.

About the Power Supply

I recommend to use high quality 18650 batteries (3.7v - 4.2v, 2200mAh, at least 2C of discharge rate).
