In this lesson, we will add 5 channel black/white tracking sensor module to the framework built in Lesson 1. If you have not completed installation in Lesson 1, please review Lesson 1
The software in this lesson will read data from these 5 channel black/white tracking sensor module and automatically guide the smart car to move along the black track line in the white ground.

Hardware Installation:
Step 1: Motor driver(Model-X )pin installation.
Start the installation from previous status of Smart Car Lesson 1 . If you have installed Lesson 2 or 3, you must remove the wires which you connected in lesson2 and lesson3.
Step 2: Install tracking sensor modules under lower car chassis with 2pcs M3 plasctic screws, M3 plastic pillars and M3 plastic nuts.
Step 3: Connect GND-VCC pin of tracking sensor module to GND-5V of OSOYOO Uart WiFi shield V1.3; connect IR1, IR2, IR3, IR4, IR5 pins to A0, A1, A2, A3, A4 with 7pin 25cm female to female cable as the following photo shows (Remember : DO NOT remove any existing wires installed in Lesson 1 ):
Open-source Arduino Software(IDE) |
Download IDE here: https://www.arduino.cc/en/Main/Software?setlang=en |
|
7 zip is a free zip utility that un-zips zip files |
Download 7zip here for free https://www.7-zip.org/ |
Step 1: Install latest IDE (If you have IDE version after 1.1.16, please skip this step). Download IDE from https://www.arduino.cc/en/Main/Software?setlang=en , then install the software.
Step 2: Download Lesson 4 tracking smart car sample code from v2smartcar-lesson4 , unzip the download zip file smartcar-lesson4.zip, you will see a folder called smartcar-lesson4B .
Step 3: Connect OSOYOO basic board to PC with USB cable, Open IDE -> click file -> click Open -> choose code “smartcar-lesson4.ino” in smartcar-lesson4 folder, load the code into your board.
Step 4: Choose corresponding board/port for your project,upload the sketch to the board.
Step 5: Adjust the sensitivity of tracking sensor modules. Turn on and hold the car and adjust the potentiometer on the tracking sensor with Philips screwdriver until you get the best sensitivity status: the signal indicate LED light will turn on when sensor is above black track, and the signal LED will turn off when the sensor is above white ground
Prepare a black track (the width of the black track is more than 20mm and less than 30mm) in white ground. Please note, the bend angle of track can’t be larger than 90 degree. If the angle is too large, the car will move out of the track.
Turn on the car and put the middle of tracking sensor module facing over black track, and then the car will move along the black track.
