Introduction: DO NOT ENTER: Arduino Leonardo LED Photo-resistance Reminder Light

The light is for reminding people from enter in dangerous or place shouldn't go in. People have the need can DIY the light. Every like Family, student, teenagers who have a interest can start to make it!!!

The project is alter from: https://www.instructables.com/Arduino-Leonardo-Ch...

The original project are making a Christmas decoration light, In my project I add a photo-resistance to detect there are people coming or not. The use of it are totally different.

Supplies

carbon film resistor x 1

metallic resistance x 1

Arduino Leonardo circuit board x 1

LED light x 1

Wire x 7

USB 20 cable 1.5m x 1

transparent box x 1

marker

paper

Step 1: Step 1: Assembly Resistor on Arduino Leonardo

Follow the picture and place the materials on the right place.

Step 2: Step 2: Start Write Down the Arduino Code

copy down the code

If you don't know how to type a code, you can also use ArduBlock. here is a link of how to download ArduBlock : https://www.davidhuanglab.com/ardublock

Step 3: Step 3: Write Down Your Own Reminder

Using paper and marker, design your word, structure... everything you want.

Step 4: Step 4: Upload the Code

connect USB cable on the computer, click upload on the computer.

Step 5: Step 5: Final Result
