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. Install the IR receiver module with 2pcs M2.5*10 plastic screws, M2.5 plastic pillars and M2.5 plastic nuts at the front of upper chassis.
Step 3: Connect the S pin in IR receiver to D10 pin in UNO board, GND to GND, VCC to 5V, as the following photo (Remember : DO NOT remove any existing wires installed in Lesson 1 ) :

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)
Download IRremote library from https://osoyoo.com/wp-content/uploads/samplecode/IRremote.zip, then import the library into Arduino IDE(Open Arduino IDE-> click Sketch->Include Library->Add .Zip Library)
Step 3: Download Lesson 2 IRremote smart car sample code fromhttps://osoyoo.com/driver/v2smartcar-lesson2.zip and unzip the download zip file smartcar-lesson2.zip, you will see a folder called smartcar-lesson2.
Step 4: Connect UNO R3 board to PC with USB cable, Open Arduino IDE -> click file -> click Open -> choose code “smartcar-lesson2.ino” in smartcar-lesson2 folder, load the code into arduino.(Notice: Shut off your battery or Unplug your power adapter when upload sketch code to Arduino.)
Step 5: Choose corresponding board and port for your project,upload the sketch to the board.
Some user found that this IR remote does not work. The reason might be the IR remote sends different button code which does not match our sample code. In order to solve this problem. Please take following steps:
Step A) Get the IR code of each button in your IR remote.
Copy code from following link:https://osoyoo.com/wp-content/uploads/samplecode/irdemo.zip
upload above sketch into your Arduino and open the serial monitor in your upper-right corner.
Write down the IR code of your control buttons “▲” “▼” “>” “<
