Complete Arduino project to build a Remote Controlled Car together with the bluetooth linked Remote Controller

RemoteControlled Car build with Arduino Uno/Nano and communication via Bluetooth

Software for Arduino Uno-based remote controlled car together with a Arduino Nano-based remote controlling and intercommunication via Bluetooth modules.

Hardware components used for Remote Controlled Car

• Arduino Uno or compatible
• Battery or powerbank [ 5V, +1450 mAh ] to power-up Arduino and its components (bluetooth module and speaker)
• Battery or powerbank [ 12V, +4000 mAh ] to power-up motors
• Bluetooth HC-06 slave module
• L298N Driver to control motors
• Buzzer / piezo speaker
• 4 DC motors + wheels
• Optional dip switch to turn on/off the car
• Car structure, up to your imagination :-)

Hardware components used for Remote Controller

• Arduino Nano or compatible
• Battery or powerbank [ 5V, +1450 mAh ]
• Bluetooth HC-05 master/slave module
• Joystick analog 2-Axis with button
• Three switch buttons
• Optional dip switch to turn on/off the controller
• Controller structure, also up to your imagination

Software structure

The software is splitted into Abstraction Layers so the responsability of each layer are very limited and will make easier the growth and maintenance of the project in a Architectural point of view. Using a objected-oriented language such as C++ accepted by Arduino, makes the implementation closer to this approach.

Dependencies: Needs to have access to Generic-Libraries/lib in this same repository

arduino-rc-car's Issues

Change SpeedMode when in movement

Change SpeedMode if corresponding button is pressed and car is in movement with speed , if possible due to lack of concurrency/parallel processing capabilities in ATmega328P -> Use and apply the new imported FreeRTOS library for parallel processing like change SpeedMode when in movement or allow reproduce melodies together with movement. Check issue #4 for Arduino-Generic-Libraries

Different speeds for motor axes

Move simultaneously both axes but at different speed instead of only moving one axis when changing car's direction
