Objection 下图不适合做本教程首图,很多器件如寻迹超声波等传感器本教程不需要,请重新拍摄


In this tutorial, we will use Osoyoo Smart DIY kit to make a simple remote controlled smart car. Once the car installation is completed, we will use a Infrared Remote to control the car movements including go forward, go back, left turn and right turn

Step 1: Install the smart car basic frame work  as per Smart Car Lesson 1 . If you have already completed installation in Lesson 1 , just keep it as is.
Step 2: Add an IR receiver module onto the car. Connect the S pin in IR to D3 pin in UNO board. Remember : DO NOT remove any existing wires installed in Lesson 1 . You can stick the IR receiver module onto chassis with a tape or screw it into any empty hole in the chassis .

Software Installation:

Step 1: Install latest Arduino IDE (If you have Arduino IDE version after 1.1.16, please skip this step)

Download Arduino IDe from https://www.arduino.cc/en/Main/Software?setlang=en , then install the software.

Step 2: Install IRremote library into Arduino IDE (If you have already installed IRremote library, please skip this step)

Down load IRremote library from  http://osoyoo.com/wp-content/uploads/samplecode/IRremote.zip, then import the library into Arduino IDE(in Arduino IDE->Sketch->Import Library->Add Library)

Step 3: Download IRremote small car sample code and run the car with a remote controller.

Sample code download url:smartcar-lesson2.zip

Download above file and load it into Arduino IDE.

Press IR controller keys to control the car movements as per following instruction table:

IR remote key Car activity
Go forward
Go backward
< Left turn
> Right turn
OK Stop
