Page 5: Introduction
Introduction Relays are used to control AC circuits, switching them ON or OFF. The relay is one of the most important control elements. It is an electrical switch that responds to a signal received from the microcontroller (like in Atmega328p or Raspberry Pi). Relays are widely used in remote control, communications, mechatronics devices, power electronic devices, etc. - Page 6 On the DC side of the board there are two rows of 8 pins for connecting on the D1 Mini board. The shield uses 3.3V pin, GND pin and digital I/O pin 5 (labeled as D1, this is further explained later in the text). To change the state of the relay, change the sate of digital I/O pin 5.

Page 11: 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. - 9 -... - Page 12 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 13 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 14 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. - 12 -...
