Page 5: Introduction
Introduction The KY-003 Hall-effect sensor module has the 3144 Hall magnetic sensor, a resistor and a red LED on-board. The module is a very responsive switch that gets activated by a magnetic field. It can be triggered, with high response rates, by a natural magnet or an electromagnet. -
Page 6: Specifications
Dimensions: 19 x 15mm [0.73 x 0.6in] The KY-003 Hall sensor module consists of a sensitive Hall-effect switch, a 680Ω resistor and a red LED. The red LED gets turned ON when there is a magnet in the sensor proximity. -
Page 7: The Pinout
The pinout The KY-003 Hall-effect sensor module has three pins. The pinout diagram is shown on the following image: - 5 -... -
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 -...
