Linkit One Automatic Night Light




About: My name is Zach Sousa and I'm a Canadian highschool student that has a passion for making.

Hey everyone! In this instructable, I will show you how to make an automatic nightlight that turns on when you step out of bed. This project uses a PIR motion sensor that detects infrared light, which in turn, can detect movement of living things.

Step 1: Parts and Tools

Here are the parts and tools needed to make this project:



Linkit ONE microcontroller

Lithium Ion battery (Included with linkit ONE)

PIR sensor

3mm acrylic sheet


Male Headers


Computer with latest version of the Arduino IDE and Linkit ONE drivers

Soldering iron and solder

Hot glue and hot glue gun

Band saw

Step 2: Wiring

Use the attached circuit diagram to wire all connections in the project.

Step 3: Cut Acrylic

Print out the attached template and glue it to a piece of acrylic. Now, cut out the acrylic according to the template.

Step 4: Build Enclosure

Assemble the enclosure by glueing all of the side pieces (the short long pieces) together to make a rectangle. Now, glue the big translucent rectangular piece to the bottom of the hollow rectangle shape that you made in the last step.

Step 5: Glue Sensor

Hot glue the PIR sensor to the box, I glued mine behind the translucent white plastic on the box.

Step 6: Code

Download the attached code and open it. Next, plug in the linkit one to your computer and select the correct serial port (should say "linkit one"). Now, click upload.

Step 7: Done!

Thank you for viewing this instructable! If you liked it, please "like", comment, or share it.

To use this project, Place the device under your bed, making sure that the motion sensor will be able to detect the infrared light given off of your feet. As long as it isn't behind anything, you should be fine.

    In step 3 you say "Print the attached template" - what template?

    Sorry, I guess the .svg file isn't readable through instructables. I'll try uploading it as a .pdf later.

    Awesome work! I like that you made an enclosure for your project.
