    Arduino Quick Start Guide


    Installing the Arduino IDE

    1. Go to and download the appropriate version for your system.
    2. Run the installation file (usually called arduino-1.xx.xx-windows.exe).
    3. Follow the on-screen instructions to complete the installation process.

    Connecting the Arduino to a computer

    1. Connect the Arduino to your computer using the USB cable provided.
    2. Open the Arduino IDE and click on “Tools”. When prompted by windows firewall click allow.
    3. Move the cursor over “Board” and select your Arduino board from the list (e.g. “Arduino Uno”).
    4. Click on “Tools” again and move the cursor over “Port”. Now, select the USB port where the Arduino is plugged in. If you have multiple devices under “Ports” and you are unsure which one is the Arduino, try selecting one of the ports and then click on “Tools” and select “Get board info”. If the Arduino port is selected, a small window displaying the board information will appear, otherwise keep trying different ports until the window appears.
    5. To check if the Arduino is connected correctly, click on the “Upload” button at the top of the screen (button with arrow pointing to the right) and wait for the empty sketch to upload. If no errors come up, you’re all set up and ready to go!

    Installing Arduino Libraries

    Method 1

    1. Open the Arduino IDE and click on “Tools” at the top of the screen.
    2. Click on “Manage Libraries”.
    3. Type in the name of the library you wish to install (e.g. “CCS811”) and press enter.
    4. The Library Manager will now display a number of relevant libraries. Hover the cursor over the required library and click “Install”. When the installation has finished, close the Library Manager window.

    Method 2

    1. Download the library you wish to install.
    2. Extract the folder from the zip file and paste it in the following location:

             Windows XP and above: C:\Users\%username%\Documents\Arduino\Libraries

             Mac: /Users/<username>/Documents/Arduino/libraries/

             Linux: /usr/share/arduino/libraries/ (you must delete the dashes in the folder name, if there are any)

    1. Restart the Arduino IDE.

PIR sensor module for Arduino and other microcontroller projects

The HCSR501 is a PIR (Passive Infra-Red) sensor that can detect the presence of people by measuring the infrared radiation radiated by the body. It can be used in a vast and diverse number of projects, including but not limited to: automated lighting systems, burglar alarms, automated door systems, etc.

Principle of operation
All objects with a temperature above absolute zero (0 kelvin) emit electromagnetic radiation. The higher the temperature of the object, the smaller the wavelength of the radiation emitted. The normal human body temperature is 37°C (310.2 kelvin) and it therefore emitts infrared radiation (mostly at a wavelength of 12µm). The PIR sensor can sense when a person has walked into its field of view by measuring the difference in the infrared radiation received from the ambient environment and the human body. 
Voltage : 5-20VDC
Power Consumption: 64mA
Logic output: 3.3V
Range: 7 metres, (<120°)
Lock Time: 200 miliseconds
Operating temperature range: between -15°C and 70°C
