Page 5: Introduction
Introduction The KY-033 line-tracker sensor module uses an infrared transmitter and receiver that detects how reflective the surface is. On-board the KY-033 module there are the LM393 dual analog voltage comparator chip, a potentiometer, a status LED, two resistors and TCRT5000 infrared transmitter and receiver. -
Page 6: Specifications
Specifications » Operating voltage range: from 3.3V to 5V DC » Working current: ~20mA » Detection distance: from 5mm to 150mm » Detection angle: 35° » Dimensions: 42 x 11mm [1.65 x 0.4in] The transmittting part of the TCRT5000 emits infrared light at a certain frequency, light bounce back from the surface and gets detected by an infrared light detector. -

Page 8: How To Set-Up Arduino Ide
How to set-up Arduino IDE If the Arduino IDE is not installed, follow the link and download the installation file for the operating system of choice. For Windows users, double click on the downloaded .exe file and follow the instructions in the installation window. - 6 -... - Page 9 For Linux users, download a file with the extension .tar.xz, which has to be extracted. When it is extracted, go to the extracted directory and open the terminal in that directory. Two .sh scripts have to be executed, the first called arduino-linux-setup.sh and the second called install.sh.
- Page 10 Almost all operating systems come with a text editor preinstalled (for example, Windows comes with Notepad, Linux Ubuntu comes with Gedit, Linux Raspbian comes with Leafpad, etc.). All of these text editors are perfectly fine for the purpose of the eBook. Next thing is to check if your PC can detect an Atmega328p board.
- Page 11 If the Arduino IDE is used on Windows, port names are as follows: For Linux users, for example port name is /dev/ttyUSBx, where x represents integer number between 0 and 9. - 9 -...
